     All defined terms under Rule 4-10(a) of Regulation S-X shall have their
statutorily prescribed meanings when used in this report. Quantities of natural
gas are expressed in this report in terms of thousand cubic feet (Mcf), million
cubic feet (MMcf) or billion cubic feet (Bcf). Oil is quantified in terms of
barrels (bbls), thousands of barrels (Mbbls) and millions of barrels (MMbbls).
Natural gas is compared to oil in terms of barrels of oil equivalent (boe) or
million barrels of oil equivalent (MMboe). Oil and natural gas liquids are
compared with natural gas in terms of million cubic feet equivalent (MMcfe) and
billion cubic feet equivalent (Bcfe). One barrel of oil is the energy equivalent
of six Mcf of natural gas. Daily oil and gas production is expressed in terms of
barrels of oil per day (b/d) and thousands of cubic feet of gas per day (Mcf/d)
or millions of British thermal units per day (MMBtu/d), respectively. Gas sales
volumes may be expressed in terms of one million British thermal units (MMBtu),
which is approximately equal to one Mcf. With respect to information relating to
the Company's working interest in wells or acreage, "net" oil and gas wells or
acreage is determined by multiplying gross wells or acreage by the Company's
working interest therein. Unless otherwise specified, all references to wells
and acres are gross.

                                     PART I
 
ITEM 1. BUSINESS
 
GENERAL
 
     Apache Corporation (Apache or the Company), a Delaware corporation formed
in 1954, is an independent energy company that explores for, develops and
produces natural gas, crude oil and natural gas liquids. In North America,
Apache's exploration and production interests are focused on the Gulf of Mexico,
the Anadarko Basin, the Permian Basin, the Gulf Coast and the Western
Sedimentary Basin of Canada. Outside of North America, Apache has exploration
and production interests offshore Western Australia and in Egypt, and
exploration interests in Indonesia, offshore The People's Republic of China and
offshore the Ivory Coast. Apache common stock, par value $1.25 per share, has
been listed on the New York Stock Exchange since 1969, and on the Chicago Stock
Exchange since 1960.
 
     Apache holds interests in many of its U.S., Canadian and international
properties through operating subsidiaries, such as MW Petroleum Corporation
(MW), Apache Canada Ltd., DEK Energy Company (DEKALB, formerly known as DEKALB
Energy Company), Apache Energy Limited (AEL, formerly known as Hadson Energy
Limited), Apache International, Inc., Apache Overseas, Inc. and The Phoenix
Resource Companies, Inc. Properties referred to in this document may be held by
those subsidiaries. Apache treats all operations as one segment of business.
 
1996 RESULTS
 
     In 1996, Apache had net income of $121.4 million, or $1.42 per share, on
total revenues of $977.2 million. Net cash provided by operating activities
during 1996 was $490.5 million.
 
     The year 1996 was Apache's 19th consecutive year of production growth and
ninth consecutive year of oil and gas reserves growth. Apache's average daily
production was 53.2 Mbbls of oil and 561 MMcf of natural gas for the year.
Giving effect to 1996 acquisitions, dispositions and drilling activity, the
Company's estimated proved reserves increased by 85.6 MMboe in 1996 over the
prior year to 506.2 MMboe, of which approximately 54 percent of total reserves
was natural gas. Based on 420.6 MMboe reported at year-end 1995, Apache's
reserve growth during the year reflects replacement of 257 percent of the
Company's 1996 production, including approximately 179 percent through drilling,
revisions, recompletions, workovers and other production enhancement projects.
Apache's active drilling and production-enhancement program yielded 279 new
producing U.S. and Canadian wells out of 370 attempts and involved 344 major
North American workover and recompletion projects during the year.
 
     At December 31, 1996, Apache had interests in approximately 4,564 net oil
and gas wells and 1,523,405 net developed acres of oil and gas properties. In
addition, the Company had approximately 791,627 net undeveloped acres under U.S.
and Canadian leases and 6,881,900 net undeveloped acres under international
exploration and production rights.
 
APACHE'S GROWTH STRATEGY
 
     Apache's growth strategy is to increase oil and gas reserves, production,
and cash flow through a combination of exploratory drilling, development of its
inventory of existing projects and, principally in North America, tactical
acquisitions meeting defined financial parameters. The Company's drilling
program emphasizes reserve additions through exploratory drilling primarily on
its international interests, and moderate-risk drilling primarily on its North
American interests. The Company also emphasizes reducing operating costs per
unit produced and selling marginal and non-strategic properties in order to
increase its profit margins.
 
     Apache's international investments and exploration activities are an
important component of its long-term growth strategy. Although international
exploration is recognized as higher-risk than most of Apache's U.S. and Canadian
activities, it offers potential for greater rewards and significant reserve
additions. Apache directed its international efforts in 1996 toward development
of certain discoveries offshore Western Australia
 
                                        1
   4
 
and in Egypt, and toward further exploration efforts on its concessions in
Egypt, offshore The People's Republic of China, in Indonesia, and offshore the
Ivory Coast of western Africa. Apache believes that reserve additions in these
international areas may be made through higher-risk exploration and through
improved production practices and recovery techniques.
 
     For Apache, property acquisition is only one phase in a continuing cycle of
business growth. Apache's aim is to follow each acquisition with a cycle of
reserve enhancement, property consolidation and cash flow acceleration,
facilitating asset growth and debt reduction. This approach requires a
well-planned and carefully executed property development program and, where
appropriate, a selective program of property dispositions. It motivates Apache
to target acquisitions that have ascertainable additional reserve potential and
to apply an active drilling, workover and recompletion program to realize the
potential of the acquired undeveloped and partially developed properties. Apache
prefers to operate its properties so that it can best influence their
development; as a result, the Company operates properties accounting for over 75
percent of its production.
 
1996 ACQUISITIONS AND DISPOSITIONS
 
     The Company entered into the Agreement and Plan of Merger dated March 27,
1996 (the Merger Agreement) with The Phoenix Resource Companies, Inc. (Phoenix),
providing for a merger in which Phoenix would become a wholly owned subsidiary
of the Company (the Merger). On May 20, 1996, the transaction was approved by
the Phoenix shareholders and the Merger was consummated. Pursuant to the Merger
Agreement, each of the 16.2 million shares of Phoenix common stock then
outstanding was converted into the right to receive .75 shares of Apache common
stock, with any fractional shares paid in cash, without interest, and $4.00 in
cash, resulting in a total of 12.2 million shares of Apache common stock being
issued and approximately $65 million being paid in respect of the Phoenix common
stock.
 
     Phoenix's principal assets are its interest in the Khalda and Qarun oil and
gas concessions located in the Western Desert of Egypt, which in the aggregate
contain 18 oil fields and six gas fields. Phoenix's oil and gas operations are
currently conducted through Egyptian operating companies owned jointly by the
Egyptian General Petroleum Corporation (EGPC), Phoenix and certain other
participants, including the Company in the Qarun concession. In conjunction with
the Merger, George D. Lawrence Jr., former president and chief executive officer
of Phoenix, joined Apache's board of directors.
 
     During 1996, Apache also acquired oil and gas properties and seismic data
in North America and Egypt in transactions whose purchase prices totaled
approximately $115 million, the most significant of which was the purchase of
interests in offshore blocks in the Gulf of Mexico from Hall-Houston Oil Company
(Hall-Houston) and related entities in August for approximately $46 million. In
1996, Apache also disposed of oil and gas properties and gas plants in
transactions whose sales proceeds totaled approximately $30.1 million. In
addition, Apache monetized certain gas properties entitled to Internal Revenue
Code Section 29 Tax Credits in two transactions with the Apache Series 1996-A
Trust, whose managing trustee is Apache and whose non-managing trustee is FC
Energy Finance I, Inc. Total net proceeds from these two transactions were
approximately $23 million.
 
EXPLORATION AND PRODUCTION
 
     The Company's North American exploration and production activities are
divided into five operating regions Offshore, Midcontinent, Western, Gulf Coast
and Canadian regions. Approximately 82 percent of the Company's proved reserves
are located in the five North American regions. Following the Phoenix Merger,
Egypt became an important region for Apache. The Company's Egyptian operations
are headquartered in Cairo. Apache conducts its Australian exploration and
production and its Indonesian exploration through its Australian region.
Information concerning the amount of revenue, operating income and identifiable
assets attributable to U.S., Canadian and international operations,
respectively, is set forth in the Supplemental Oil and Gas Disclosures under
Item 8 below.
 
     Offshore. The Offshore region (referred to as the Gulf of Mexico region in
1995) includes all of Apache's interests in properties offshore Texas, Louisiana
and Alabama. In 1996, Offshore produced approximately 11.8 MMboe and $181
million in production revenue for the year. At December 31, 1996, the
 
                                        2
   5
 
Offshore region held 346,806 net acres, located in both state and federal
waters, and accounted for 45.8 MMboe, or nine percent, of the Company's year-end
1996 total estimated proved reserves. Apache's operations in the Offshore region
focused on workovers and recompletions, which totaled 33 in the region for 1996.
Apache participated in 19 wells which were drilled in the region during the
year, 10 of which were completed as producers. For 1996, Apache's gas production
from the Offshore region was approximately 61,554 MMcf.
 
     Midcontinent. Apache's Midcontinent region operates in Oklahoma, eastern
Texas and northern Louisiana. The region has focused operations on its sizable
position in the Anadarko Basin of western Oklahoma. Apache has drilled and
operated in the Anadarko Basin for nearly four decades, developing an extensive
database of geologic information and a substantial acreage position. The
Midcontinent region produced approximately 12 MMboe for the year, creating $167
million in production revenue for the Company.
 
     At December 31, 1996 Apache held an interest in 409,033 net acres in the
region, which accounted for approximately 106.5 MMboe, or 21 percent, of
Apache's total estimated proved reserves. Apache participated in drilling 103
wells in the Midcontinent region during the year, 85 of which were completed as
producing wells. The Company performed 26 major workover and recompletion
operations in the region during 1996.
 
     Western. The Western region includes assets in the Permian Basin of western
Texas and New Mexico, the Green River Basin of Colorado and Wyoming and the San
Juan Basin of New Mexico. The Western region was Apache's leading region for oil
and gas sales for 1996, producing approximately 10.4 MMboe and $185 million in
oil and gas revenue, 22 percent of the Company's production revenues during
1996. At December 31, 1996, the Company held 649,820 net acres in the region,
which accounted for 137.4 MMboe, or 27 percent, of the Company's total estimated
proved reserves. Apache participated in drilling 128 wells in the Western
region, 103 of which were productive wells. Apache performed 30 major workovers
and recompletions in the Western region during the year.
 
     Gulf Coast. The Gulf Coast region encompasses the Texas and Louisiana
coasts, central Texas and Mississippi. In 1996, the Gulf Coast region
contributed approximately $182 million in revenues from production of 9.9 MMboe
for the year. The region was one of the most active in the Company in the number
of workover and recompletion projects completed and the number of wells drilled.
The Company performed 226 major workover and recompletion operations during 1996
in the Gulf Coast region and participated in drilling 43 wells, 31 of which were
completed as producers. As of December 31, 1996, the region encompassed 273,568
net acres, and accounted for 69.5 MMboe, or 14 percent, of the Company's
year-end 1996 total estimated proved reserves.
 
     Canada. Exploration and development activity in the Canadian region is
concentrated in the Provinces of Alberta and British Columbia. The region
produced approximately 5.5 MMboe, 83 percent of which was natural gas, and
generated $48 million in oil, gas and natural gas liquids sales, six percent of
the Company's production revenues in 1996. Apache participated in drilling 77
wells in this region during the year, 50 of which were completed as producers.
The Company performed 29 workovers and recompletions on operated wells during
1996. At December 31, 1996, the region encompassed approximately 409,120 net
acres, and accounted for 57.1 MMboe, or 11 percent, of the Company's year-end
1996 total estimated proved reserves.
 
     Egypt. At year end, Apache held 6,051,867 net acres in Egypt, accounting
for 58.6 MMboe of estimated proved reserves or 12 percent of Apache's total
estimated proved reserves. As a result of the acquisition of Phoenix in May 1996
(see "1996 Acquisitions and Dispositions"), Apache owns a 75 percent interest in
the Qarun Block and a 40 percent interest in the Khalda Block, both in the
Western Desert of Egypt. At year end, the Qarun Block, which Apache operates,
consisted of approximately 1,927,000 acres, of which approximately 46,500 were
classified as developed. Currently, the Qarun Block is producing approximately
27,000 b/d from 13 wells, which is being sold to EGPC. The Khalda Block consists
of approximately 2,416,000 acres, of which approximately 318,500 were classified
as developed as of year end. The Khalda Block is currently producing
approximately 33,000 b/d from 78 wells, which is transported to market by
pipeline to a point west of Alexandria, Egypt. Future production of gas from
Khalda is expected to be delivered for sale to EGPC at a point west of
Alexandria, Egypt, via a 34-inch gas pipeline, construction of which is
scheduled to commence in
 
                                        3
   6
 
1997 and to be completed by 1999. The costs of building the pipeline will be
borne by Apache, the other Khalda participants and the owners of a neighboring
block. Construction costs paid by Apache and the other Khalda participants will
be recoverable from oil and gas production from the Khalda Block.
 
     Both the Khalda and Qarun Concession Agreements provide that Apache and its
partners in the concessions will pay all of the operating and capital costs for
developing the concessions, while the production will be split between EGPC and
the partners. Up to 40 percent of the oil and gas produced from each of the
concessions is available to the Company and its partners to recover operating
and capital costs for the applicable concession. To the extent eligible costs
exceed 40 percent of the oil and gas produced and sold from a concession in any
given quarter, such excess costs may be carried into future quarters without
limit. The remaining 60 percent of all oil and gas produced from the concessions
is divided between EGPC and Apache and its partners, with the percentage
received by Apache and its partners reducing as the gross daily average of oil
and gas produced on a quarterly basis increases. Under the Khalda Agreement,
capital costs are amortized over four years, while the Qarun agreement provides
for a five year amortization.
 
     In addition to the Qarun and Khalda Blocks, Apache holds a 50 percent
interest in 459,600 acres in the Darag Block in the northern Gulf of Suez, and a
50 percent interest in the 6,820,000 acre East Beni Suef Block immediately to
the south of the Qarun Block. Both the Darag and East Beni Suef Blocks are in
the early stages of evaluation, and exploratory drilling is expected to begin in
the latter part of 1997. In January 1997, Apache completed the purchase from
Mobil Exploration Egypt, Inc. of interests in three blocks in the Western Desert
of Egypt; a 24 percent interest in the 3,212,000-acre North East Abu Gharadig
Block, a 50 percent interest in the 1,384,000-acre East Bahariya Block, and a
one-third interest in the 3,100,000-acre West Mediterranean Block No. 1 (partly
onshore and partly offshore).
 
     Australia. Western Australia became an important region for Apache after
the 1993 acquisition of Hadson Energy Resources Corporation (subsequently known
as Apache Energy Resources Corporation or AERC). In 1996, the region generated
three percent of the Company's revenues for the year. Natural gas production in
the region increased by 45 percent from the prior year to approximately 13.9
MMcf/d in 1996. Average daily oil production decreased by 26 percent to
approximately 2,318 b/d in 1996, primarily as a result of natural depletion. As
of December 31, 1996, Apache held 64,410 net developed acres and 607,878 net
undeveloped acres in Western Australia. Apache acts as operator for most of its
properties in Western Australia through a wholly owned subsidiary, AEL.
 
     During 1996, Apache's estimated proved reserves in Australia increased by
60 percent to 31.3 MMboe, six percent of the Company's total estimated proved
reserves at year end. The increase in Australia reserves was primarily
attributable to natural gas reserves booked at the East Spar discovery which
were recorded only after the Company had entered into agreements for the sale
and delivery of such gas. Through AEL and its subsidiaries, Apache operates the
Harriet Gas Gathering Project, a gas processing and compression facility with a
throughput capacity of 100 MMcf/d, and a 60-mile, 12-inch offshore pipeline with
a throughput capacity of 175 MMcf/d. See "Oil and Natural Gas Marketing."
 
     Other International Operations. Outside of Canada, Egypt and Australia,
Apache currently has exploration interests in Indonesia, offshore The People's
Republic of China and offshore the Ivory Coast.
 
     In Indonesia, Apache holds a 39 percent interest in and operates the Bentu
Segat Block on Central Sumatra, on which an undeveloped gas field is located.
Negotiations with potential buyers for the gas are continuing.
 
     Apache is also the operator, with a 50 percent interest, of the Zhao Dong
Block in the Bohai Bay, offshore The People's Republic of China. In 1994 and
1995, discovery wells tested at rates between 1,300 and 4,000 b/d of oil. The
Company elected to proceed with the second exploration phase, commencing in May
1996, which involves a commitment to drill two additional exploratory wells. In
early 1997, a new well tested at rates up to 11,571 b/d of oil, and the Company
is currently evaluating the discovery areas for commercial potential. In March
1997, Apache gave XCL-China Ltd., which is the owner of the remaining 50 percent
interest in the Zhao Dong Block, default notices of nonpayment totaling
approximately $7.8 million (not including interest) owed on its share of joint
account expenses.
 
                                        4
   7
 
     In the Ivory Coast, Apache drilled an exploratory well in 1996 on the CI-27
offshore Block, confirming the existence of substantial reserves of gas in the
Foxtrot field and the produceability of some oil from the field's lower
horizons. Apache is the operator of the block, holding a 40 percent interest.
Discussions with potential gas buyers are taking place.
 
OIL AND NATURAL GAS MARKETING
 
     On October 27, 1995, wholly owned affiliates of each of Apache, Oryx Energy
Company and Parker & Parsley Petroleum Company formed Producers Energy
Marketing, LLC, a Delaware limited liability company (ProEnergy). ProEnergy
became fully operational on April 1, 1996, and markets substantially all of its
members' domestic natural gas pursuant to member gas purchase agreements having
an initial term of 10 years, subject to early termination following specified
events. The price of gas purchased by ProEnergy from its members is based upon
agreed to published indexes. ProEnergy also provides its members with certain
contract administration and other services.
 
     ProEnergy's limited liability company agreement provides that capital
funding obligations, allocations of profit and loss and voting rights are
calculated based upon the members' respective throughputs of natural gas sold to
ProEnergy. Each member's liability with respect to future capital funding
obligations is subject to certain limitations. Natural gas throughputs are
calculated, profit distributed, and/or capital called on a quarterly basis. As
of December 31, 1996, the Company held an approximate 44 percent interest in
ProEnergy.
 
     Apache is delivering natural gas under several long-term supply agreements
with terms greater than one-year. In connection with the acquisition of
substantially all of the oil and natural gas assets (the Aquila Assets) of
Aquila Energy Resources Corporation (Aquila) in September 1995, the Company
entered into a five-year, four-month premium-price gas contract under which
Aquila Energy Marketing Corporation agreed to purchase 20 to 25 MMcf of gas per
day from Apache at a price of $2.80 per Mcf in 1997, escalating to $3.20 per Mcf
in the year 2000. In December 1994, the Company signed a long-term gas contract
under which Apache received an advance payment of $67.4 million. Apache will
supply the purchaser with approximately 43 Bcf of gas over a six-year period
which began in January 1995, with volumes averaging 20 MMcf/d.
 
     Apache is also delivering natural gas under several such contracts with
various cogeneration facilities. One such agreement provides that Apache will
supply a minimum of 51.1 Bcf over 10 years for use in electric power generation
from a cogeneration facility located in northeast Texas. Under the agreement,
deliveries of approximately 20 MMcf/d began in early 1997. Another such
agreement, which expires at the end of September 2005, requires Apache to
deliver 20 MMcf/d to a cogeneration facility at a price escalating yearly. In
1996, the price under this agreement was $3.08 per MMcf. Apache is also a party
to an agreement that provides for delivery of up to 9.6 MMcf/d to a cogeneration
facility at a price that escalates yearly. As of the end of 1996, the price
under this agreement was $3.10 per MMcf. The final agreement, which will
terminate at the end of 2001, calls for Apache to supply up to 12 MMcf/d.
 
     Apache assumed its own U.S. crude oil marketing operations in 1992. Most of
Apache's crude oil production is sold through lease-level marketing to refiners,
traders and transporters, generally under 30-day contracts that renew
automatically until canceled.
 
     Oil produced from Canadian properties is sold to crude oil purchasers or
refiners at market prices which depend on world-wide crude prices adjusted for
transportation and crude quality. Natural gas produced from Canadian properties
is sold to major aggregators of natural gas, gas marketers and direct users
under long and short-term contracts. The oil and gas contracts provide for sales
at specified prices, or at prices which are subject to change due to market
conditions.
 
     The Company diversifies the markets for its Canadian gas production by
selling directly or indirectly to customers through aggregators and brokers in
the United States and Canada. Apache transports natural gas via the Company's
firm transportation contracts to California (12 MMcf/d) and to the Province of
Ontario, Canada (four MMcf/d) through end-users' firm transportation contracts.
Pursuant to an agreement entered into in 1994, the Company is also selling five
MMcf/d of natural gas to the Hermiston Cogeneration Project,
 
                                        5
   8
 
located in the Pacific Northwest of the United States. In 1996, the Company
entered into an agreement with Westcoast Gas Services, Inc. for the sale of
5,000 MMBtu/d for delivery in the United States for a 10 year term. Sales under
the contract are contingent on regulatory approval of the required pipeline
expansion, and are expected to begin in 1998.
 
     In Australia, the Company has two contracts to deliver 32 Bcf of gas from
the East Spar field for industrial uses, including mining operations, a power
station and a nickel refinery. The contracts provide for an average daily rate
of 15 MMcf/d net to the Company. To provide deliveries under the contracts while
the East Spar development is under construction, the Harriet and East Spar joint
ventures, in both of which a subsidiary of the Company is a participant, entered
into a gas sales agreement under which the Harriet Joint Venture is supplying 42
MMcf of gas per day to East Spar's industrial customers. Apache operates the
Harriet Joint Venture and acts as contractor for the East Spar Joint Venture,
holding a 22.5 percent interest in Harriet and a 20 percent interest in East
Spar.
 
     In 1995, the Harriet Joint Venture entered into a take-or-pay contract to
supply natural gas under which AEL has committed 14 Bcf of reserves for delivery
over a 10-year period. Approximately 20 Bcf of AEL's proved gas reserves are
dedicated to the Gas Corporation of Western Australia, a corporation owned by
the government of Western Australia doing business as AlintaGas, under a
long-term contract which will expire in 2001. The agreement contains take-or-pay
provisions that require AlintaGas to purchase a minimum of 35 MMcf/d
(approximately eight MMcf/d net to AEL) through the remainder of the contract
term. Payments received under this contract are in Australian dollars.
 
     AEL marketed all oil and natural gas liquids produced from its interests in
the Harriet field during 1996 through a contract with Marubeni International
Petroleum (Singapore) Pte Limited (Marubeni). Pricing under the contract in 1996
represented a fixed premium to the quoted market prices of Tapis crude oil, with
payment made in U.S. dollars. In 1996, production sold under this contract
realized an average price of $22.33 per barrel (exclusive of the impact of
hedging activities). At the beginning of January 1997, the Marubeni contract was
terminated and replaced by a similar contract with Glencore International AG,
which includes East Spar liquids production.
 
     In Egypt, oil from the Qarun Block is delivered by pipeline to tanks owned
by the Company and its partners in the Qarun Concession at the Dashour pumping
station northeast of the Qarun Block or by truck to the Tebbin refinery south of
Alexandria, Egypt. At the discretion of the operator of the pipelines, oil from
the Qarun Block is put into the two 42-inch diameter SUMED pipelines, which
transport significant quantities of Egyptian and other crude oil from the Gulf
of Suez to Sidi Kherir, west of Alexandria, Egypt, on the Mediterranean Coast.
All Qarun and Khalda crude oil is currently sold to EGPC. In 1996, the Company
and its partners in the Khalda Block entered into a take or pay contract with
EGPC, which obligates EGPC to pay for 75 percent of 200 MMcf/d of future
production of gas from the Khalda Block. Sales of gas under the contract are
expected to begin in 1999 upon completion of the gas pipeline from the Khalda
Block.
 
OIL AND NATURAL GAS PRICES
 
     Natural gas prices remained volatile during 1996 with New York Mercantile
Exchange (NYMEX) spot-market prices at the Henry Hub ranging from $1.89 per
MMbtu in October to $3.61 per MMbtu in December. Fluctuations are largely due to
natural gas supply and demand perceptions. Apache's average realized gas price
of $2.02 per Mcf for 1996 increased 29 percent from the prior-year average of
$1.57 per Mcf. Apache's 1995 average realized natural gas price was 12 percent
lower than the 1994 average price of $1.78 per Mcf.
 
     Due to minimum price contracts which escalate at an average of 80 percent
of the Australian consumer price index, AEL's natural gas production in Western
Australia is not subject to the same degree of price volatility as Apache's U.S.
and Canadian gas production; however, natural gas sales under such Australian
minimum price contracts represent less than two percent of the Company's total
natural gas sales at the end of 1996. Total Australian gas sales in 1996,
including long-term contracts and spot sales averaged $1.96 per Mcf, a five
percent increase over the 1995 average of $1.86 per Mcf.
 
                                        6
   9
 
     In Egypt, all oil production from the Khalda and Qarun Blocks is currently
sold to EGPC on a spot basis at a "Western Desert" price which is applied to
virtually all production from the Western Desert and is announced from time to
time by EGPC. On December 31, 1996, that price was $23.74 per barrel.
Discussions with EGPC regarding the possibility of exporting Qarun oil
production are continuing. Once gas sales from the Khalda Block commence, the
gas is expected to be sold for a price which on a Btu basis is equivalent to 85
percent of the price of Suez Blend crude oil, FOB Mediterranean. Based on this
pricing formula, the price of Khalda gas per Mcf (at 1000 Btu per Mcf) would
have been roughly $3.80 at the end of 1996.
 
     Oil prices remained vulnerable to unpredictable political and economic
forces during 1996, but did not experience the wide fluctuations seen in natural
gas prices during the year. Apache believes that oil prices will continue to
fluctuate in response to changes in the policies of the Organization of
Petroleum Exporting Countries (OPEC), events in the Middle East and other
factors associated with the world political environment. As a result of the many
uncertainties associated with levels of production maintained by OPEC and other
oil producing countries, the availabilities of world-wide energy supplies and
the competitive relationships and consumer perceptions of various energy
sources, the Company is unable to predict what changes will occur in crude oil
and natural gas prices.
 
     Apache's worldwide crude oil price averaged $20.84 per barrel in 1996, up
22 percent from the average price of $17.09 per barrel in 1995, and 33 percent
higher than the average price of $15.65 per barrel in 1994. The Company's
average crude oil price for its Australian production, including production sold
under the Marubeni contract, was $22.33 per barrel in 1996, 20 percent higher
than the average price in 1995.
 
     Terms of the acquisition of MW from Amoco Production Company (Amoco)
included an oil and gas price sharing provision under which certain price
sharing payments may be payable to Amoco. Under this provision, to the extent
that oil prices exceed specified reference prices that rise to $33.12 per barrel
over the eight-year period ending June 30, 1999, and to the extent that gas
prices exceeded specified reference prices that rose to $2.68 per Mcf over the
five-year period ended June 30, 1996, Apache will share the excess price
realization with Amoco on a portion of the MW production. Apache was not
required to make any price sharing payments to Amoco in 1996.
 
     From time to time, Apache buys or sells contracts to hedge a limited
portion of its future oil and gas production against exposure to spot market
price changes. See Note 9 to the Company's consolidated financial statements
under Item 8 below.
 
     The Company's business has been and will continue to be affected by future
worldwide changes in oil and gas prices and the relationship between the prices
of oil and gas. No assurance can be given as to the trend in, or level of,
future oil and gas prices.
 
RESERVE VALUE CEILING TEST
 
     Under the full cost accounting rules of the Securities and Exchange
Commission (SEC), the Company reviews the carrying value of its oil and gas
properties each quarter on a country-by-country basis. Under full cost
accounting rules, capitalized costs of oil and gas properties may not exceed the
present value of estimated future net revenues from proved reserves, discounted
at 10 percent, plus the lower of cost or fair market value of unproved
properties, as adjusted for related tax effects and deferred income taxes.
Application of these rules generally requires pricing future production at the
unescalated oil and gas prices in effect at the end of each fiscal quarter and
requires a write-down if the "ceiling" is exceeded, even if prices declined for
only a short period of time. If a write-down is required, the one-time charge to
earnings would not impact cash flow from operating activities. The Company had
no write-downs due to ceiling test limitations during 1996.
 
GOVERNMENT REGULATION OF THE OIL AND GAS INDUSTRY
 
     The Company's exploration, production and marketing operations are
regulated extensively at the federal, state and local levels, as well as by
other countries in which the Company does business. Oil and gas exploration,
development and production activities are subject to various laws and
regulations governing a wide variety of matters. For example,
hydrocarbon-producing states have statutes or regulations addressing
 
                                        7
   10
 
conservation practices and the protection of correlative rights, and such
regulations may affect Apache's operations and limit the quantity of
hydrocarbons Apache may produce and sell. Other regulated matters include
marketing, pricing, transportation, and valuation of royalty payments.
 
     At the U.S. federal level, the Federal Energy Regulatory Commission (FERC)
regulates interstate transportation of natural gas under the Natural Gas Act.
Effective January 1, 1993, the Natural Gas Wellhead Decontrol Act deregulated
natural gas prices for all "first sales" of natural gas, which includes all
sales by Apache of its own production. As a result, all sales of the Company's
natural gas produced in the U.S. may be sold at market prices, unless otherwise
committed by contract.
 
     Apache's gas sales are affected by regulation of intrastate and interstate
gas transportation. In an attempt to promote competition, the FERC has issued a
series of orders which have altered significantly the marketing and
transportation of natural gas. The effect of these orders has been to enable the
Company to market its natural gas production to purchasers other than the
interstate pipelines located in the vicinity of its producing properties. The
Company believes that these changes have generally improved the Company's access
to transportation. To date, Apache has not experienced any material adverse
effect on its gas marketing activities as a result of these FERC orders;
however, the Company cannot predict what new regulations may be adopted by the
FERC and other regulatory authorities, or what effect subsequent regulations may
have on its future gas marketing activities.
 
ENVIRONMENTAL MATTERS
 
     Apache, as an owner or lessee and operator of oil and gas properties, is
subject to various federal, provincial, state, local and foreign country laws
and regulations relating to discharge of materials into, and protection of, the
environment. These laws and regulations may, among other things, impose
liability on the lessee under an oil and gas lease for the cost of pollution
clean-up resulting from operations, subject the lessee to liability for
pollution damages, and require suspension or cessation of operations in affected
areas.
 
     Apache maintains insurance coverage which it believes is customary in the
industry, although it is not fully insured against all environmental risks. The
Company is not aware of any environmental claims existing as of December 31,
1996, which would have a material impact upon the Company's financial position
or results of operations.
 
     Apache has made and will continue to make expenditures in its efforts to
comply with these requirements, which it believes are necessary business costs
in the oil and gas industry. The Company has established policies for continuing
compliance with environmental laws and regulations, including regulations
applicable to its operations in Canada, Australia and other countries. Apache
also has established operational procedures and training programs designed to
minimize the environmental impact of its field facilities. The costs incurred by
these policies and procedures are inextricably connected to normal operating
expenses such that the Company is unable to separate the expenses related to
environmental matters; however, the Company does not believe any such additional
expenses are material to its financial position or results of operations.
 
     Although environmental requirements have a substantial impact upon the
energy industry, generally these requirements do not appear to affect Apache any
differently, or to any greater or lesser extent, than other companies in the
industry. Apache does not believe that compliance with federal, state, local or
foreign country provisions regulating the discharge of materials into the
environment, or otherwise relating to the protection of the environment, will
have a material adverse effect upon the capital expenditures, earnings or
competitive position of the Company or its subsidiaries; however, there is no
assurance that changes in or additions to laws or regulations regarding the
protection of the environment will not have such an impact.
 
COMPETITION
 
     The oil and gas industry is highly competitive. Because oil and gas are
fungible commodities, the principal form of competition with respect to product
sales is price competition. Apache strives to maintain the lowest finding and
production costs possible to maximize profits.
 
                                        8
   11
 
     As an independent oil and gas company, Apache frequently competes for
reserve acquisitions, exploration leases, licenses, concessions and marketing
agreements against companies with substantially larger financial and other
resources than Apache possesses. Moreover, many competitors have established
strategic long-term positions and maintain strong governmental relationships in
countries in which the Company may seek new entry. Apache expects this high
degree of competition to continue.
 
INSURANCE
 
     Exploration for and production of oil and natural gas can be hazardous,
involving unforeseen occurrences such as blowouts, cratering, fires and loss of
well control, which can result in damage to or destruction of wells or
production facilities, injury to persons, loss of life or damage to property or
the environment. The Company maintains insurance against certain losses or
liabilities arising from its operations in accordance with customary industry
practices and in amounts that management believes to be prudent; however,
insurance is not available to the Company against all operational risks.
 
EMPLOYEES
 
     On December 31, 1996, Apache had 1,256 employees.
 
OFFICES
 
     Apache's principal executive offices are located at One Post Oak Central,
2000 Post Oak Boulevard, Suite 100, Houston, Texas 77056-4400. At year-end 1996,
the Company maintained regional exploration and production offices in Tulsa,
Oklahoma; Houston, Texas; Calgary, Alberta; Cairo, Egypt; and Perth, Western
Australia.

ESTIMATED RESERVES AND RESERVE VALUE INFORMATION
 
     The following information relating to estimated reserve quantities, reserve
values and discounted future net revenues is derived from, and qualified in its
entirety by reference to, the more complete reserve and revenue information and
assumptions included in the Company's supplemental oil and gas disclosures under
Item 8 below. The Company's estimates of proved reserve quantities of its U.S.,
Canadian and certain international properties have been subject to review by
Ryder Scott Company Petroleum Engineers, while the proved reserve quantities of
the Company's Egyptian properties are reviewed by Netherland, Sewell &
Associates, Inc. There are numerous uncertainties inherent in estimating
quantities of proved reserves and projecting future rates of production and
timing of development expenditures. The following reserve

     The following table sets forth the estimated future value of all the
Company's proved reserves, and proved developed reserves, as of December 31,
1996, 1995 and 1994. Future reserve values are based on year-end prices except
in those instances where the sale of gas and oil is covered by contract terms
providing for determinable escalations. Operating costs, production and ad
valorem taxes, and future development costs are based on current costs with no
escalations.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
OVERVIEW
 
     Apache's results of operations and financial position during 1996 were
significantly impacted by the following factors:
 
     Commodity Prices -- Higher oil and natural gas prices contributed to record
earnings and cash flow in 1996. Apache's average realized natural gas price for
1996 was up 29 percent over 1995, favorably impacting revenues by $93.4 million.
The Company's average realized oil price for 1996 increased 22 percent from
1995, contributing $73.0 million to the increase in revenues.
 
     Phoenix Acquisition -- On May 20, 1996, Apache acquired Phoenix, through a
merger which resulted in Phoenix becoming a wholly owned subsidiary of Apache.
The assets acquired in the Phoenix acquisition contributed 6,260 b/d of oil
production during 1996.
 
     Debt Refinancing -- During 1996, Apache offered three issues of senior
unsecured notes and debentures with principal amounts of $100 million in
February, $180 million in April and $150 million in November. In October 1996,
Apache replaced its existing $1 billion revolving bank credit facility with a
global credit arrangement (global credit facility) that provides Apache with
greater borrowing availability, increased tax efficiency and a lower cost of
bank debt. Additionally, in September and October 1996, Apache received rating
upgrades on its long-term debt from Moody's Investors Service and Duff and
Phelps.
 
RESULTS OF OPERATIONS
 
NET INCOME AND REVENUE
 
     Apache reported 1996 net income of $121.4 million, up from $20.2 million in
1995. Net income per common share rose to $1.42, a five-fold increase from $.28
a year earlier, despite additional shares outstanding. Higher oil and gas prices
and increased oil production drove the increase in earnings but were partially
offset by lower natural gas production and higher lease operating expenses.
Additionally, 1995 results were negatively impacted by a one-time after-tax
charge of $8.7 million, or $.12 per share, associated with merger costs.
 
     Revenues increased 30 percent in 1996 to $977.2 million as compared to
$750.7 million for the same period in 1995. Crude oil and natural gas production
revenue increased 28 percent compared to 1995 with crude oil contributing 49
percent and natural gas contributing 50 percent of total oil and gas production
revenue.

     Natural gas sales for 1996 of $415.7 million increased $85.0 million, or 26
percent, when compared to 1995, as the impact of favorable natural gas prices
more than offset production declines. A $.53 per Mcf increase in realized price
attributable to United States natural gas production, which comprised 84 percent
of the Company's worldwide gas production, contributed $92.0 million to the
increase in sales. Offsetting this increase was a $16.2 million reduction in
sales due to a decline in United States production compared to the same period
in 1995, due primarily to the natural decline of older properties in the
Company's Offshore and Gulf Coast regions and the sale of producing properties
in late 1995. Canadian and Australian gas sales contributed $5.3 million and
$3.5 million, respectively, to the increase in revenue as a result of higher
realized prices and increased production in both countries. The Company's net
hedging activity, including fixed-price physical contracts and financial
contracts, reduced realized prices by $.09 per Mcf during the year ended
December 31, 1996, compared to a $.07 per Mcf gain during 1995. The 1995 gain
was driven substantially by higher margins on the Company's premium-price gas
contracts, given low spot market prices during 1995.

   20
 
     For the year ended December 31, 1996, oil sales increased 30 percent to
$405.7 million due primarily to the assets acquired in the Phoenix Merger.
Egyptian oil sales contributed $64.6 million, or 70 percent, of the increase in
oil sales compared to 1995, and comprised 16 percent of total oil production.
United States oil sales were favorably impacted by a 22 percent increase in
realized prices, which contributed $54.5 million to the increase in revenue
compared to 1995. Partially offsetting the impact due to higher realized
domestic prices was a 10 percent decline in domestic oil production resulting
from property sales in late 1995, which reduced revenues by $27.1 million.
Canadian oil sales contributed $2.7 million of the increase in oil sales
compared to 1995 due primarily to higher realized prices. Australian oil sales
were impacted by a 26 percent decline in production compared to 1995, partially
offset by higher realized prices, resulting in a net decrease in revenue of $2.2
million.
 
     For 1996, natural gas liquid revenues increased 27 percent to $11.7
million. Compared to the prior year, realized prices increased 36 percent,
contributing $3.1 million to the increase in revenues, while production declined
seven percent, decreasing revenues $.6 million.
 
OTHER REVENUES AND OPERATING EXPENSES
 
     During 1996, Apache's gas gathering, processing and marketing revenues
increased 47 percent to $142.9 million driven primarily by increased product
prices. Although revenues have increased with respect to these activities, lower
margins were realized for the year ended December 31, 1996 compared to the same
period in 1995.
 
     For 1996, other revenue of $1.4 million included a gain on the sale of
stock held for investment of $.8 million and Canadian royalty credits of $1.2
million. Offsetting these revenues was the impact of $.9 million of currency
transaction loss related to Canadian exchange rate fluctuations. Prior year
other revenue was $1 million lower than 1996 and included $4.3 million in
proceeds received from settlements, $2.2 million in gains from the sales of
non-oil and gas assets, $1.1 million of Canadian royalty credits and $2.1
million of other income, offset by $9.3 million in losses from the decoupling of
NYMEX and wellhead prices.
 
     The Company's depreciation, depletion and amortization (DD&A) expense for
1996 totaled $315.1 million up from $297.5 million in 1995. On an equivalent
barrel basis, full cost DD&A expense increased $.12 per boe, from $5.32 per boe
in 1995 to $5.44 per boe in 1996.
 
     Operating costs totaled $225.5 million in 1996, an increase of $13.8
million, or seven percent, from 1995. Lease operating expense (LOE), excluding
severance taxes, totaled $186.4 million, a 2.9 percent increase from 1995. On an
equivalent barrel basis, LOE for the year ended December 31, 1996, averaged
$3.43 per boe, a three percent increase from $3.34 per boe in 1995. The increase
was driven by a flat cost structure with declining production in the Gulf Coast
region and the impact of the Phoenix acquisition, partially offset by decreasing
LOE per boe in the Midcontinent region resulting from incremental production
added through the drillbit.
 
     Administrative, selling and other costs in 1996 decreased $.6 million, or
two percent. The decline is a result of the Company's continuing efforts to
control costs and its ability to integrate the assets and operations acquired in
1995 and 1996 with a minimal increase in administrative staff. On an equivalent
barrel basis, general and administrative expense declined two percent from 1995
to $.66 per boe in 1996.
 
     Net financing costs for 1996 decreased $9.0 million, or 13 percent, from
the prior year due to higher amounts of capitalized interest, partially offset
by higher gross interest costs. Capitalized interest, which is based on the
carrying value of unproved properties, increased $11.7 million for 1996 due to
the acquisitions made in 1995 and 1996 and the resulting increase in the
unproved property base. Gross interest incurred increased $1.8 million for 1996
as compared to 1995. Average corporate debt increased $78.8 million compared to
1995, increasing interest expense by $6.1 million. Offsetting this increase was
a decline of .36 percent in Apache's weighted average interest rate, resulting
in a decrease in interest expense of $4.3 million.

HEDGING ACTIVITY
 
     The Company periodically enters into hedging activities with respect to a
portion of its projected oil and natural gas production through a variety of
financial and physical arrangements intended to support oil and natural gas
prices at targeted levels and to manage its exposure to oil and gas price
fluctuations. Apache uses futures contracts, swaps, options and fixed-price
physical contracts to hedge its commodity prices. Realized gains or losses from
the Company's price risk management activities are recognized in oil and gas
production revenues when the associated production occurs.
 
     In 1996, Apache recognized net losses from hedging activities, including
both financial and fixed price physical gas contracts, which decreased oil and
gas production revenues by approximately $5.1 million and $18.7 million,
respectively. These losses decreased the Company's average realized oil and
natural gas prices in 1996 by $.26 per barrel and $.09 per Mcf, respectively.
 
PRIOR-YEAR COMPARATIVE INFORMATION
 
     Apache reported net income for 1995 of $20.2 million, or $.28 per share,
compared with $45.6 million, or $.65 per share in 1994. The decline was due to
lower natural gas realizations and non-recurring charges. Absent one-time
after-tax charges for merger costs of $8.7 million and losses recognized in
connection with the decoupling of NYMEX and wellhead prices of $5.9 million
($9.3 million before tax), 1995 earnings would have totaled $.48 per share.
 
     Revenues increased 27 percent in 1995 to $750.7 million as compared to
$592.6 million in 1994. Crude oil and natural gas production revenue increased
21 percent compared to 1994, with crude oil contributing 48 percent and natural
gas contributing 51 percent of total oil and gas production revenues.
 
     Natural gas sales for 1995 of $330.7 million increased five percent from
1994 as production gains from acquisitions and drilling more than offset the
impact of a $.21 per Mcf decline in the Company's average realized gas price.
Acquisitions boosted Apache's 1995 gas production by 92 MMcf/d, while drilling
additions outpaced the impact of property divestitures and natural depletion.
Apache realized production gains in each of its three operating areas: the
United States, Canada and Australia. In addition to production gains from
drilling, the Australian sales benefited from new markets for its natural gas.
The Company's average realized natural gas price declined 12 percent from 1994,
decreasing sales by approximately $44 million.
 
     Reflecting an increase in both production and prices, oil sales increased
45 percent in 1995 to $313.2 million. Apache's oil production rose 12.4 Mb/d, or
33 percent, from 1994 as property divestitures and natural depletion partially
offset the 17 Mb/d of production added through acquisitions. The Company's
average realized oil price increased nine percent in 1995 to $17.09 per barrel.
 
     Revenues from the sale of natural gas liquids totaled $9.2 million in 1995,
up 13 percent from 1994 due to higher prices and a slight increase in volumes.
 
     During 1995, Apache's gas gathering, processing and marketing revenues more
than doubled from 1994 to $97.2 million. Revenues increased in 1995 with respect
to these activities due to increased volumes; however, margins were lower due to
the sale of the Company's interest in the Little Knife gas plant as part of
Apache's divestiture of Rocky Mountain properties in September 1995.
 
     Other revenues in 1995 of $.4 million reflects $4.3 million of settlement
income, $2.2 million in gains from the sale of non-oil and gas assets, $1.1
million of Canadian royalty credits and $2.1 million of other income, offset by
a $9.3 million loss from the decoupling of NYMEX futures and wellhead prices.
 
     The Company's DD&A expense for 1995 totaled $297.5 million compared to
$257.8 million in 1994. On an equivalent barrel basis, full cost DD&A declined
six percent to $5.32 per boe, due to the favorable impact of reserve additions
and revisions.
 
     Operating costs totaled $211.7 million in 1995, an increase of $62.3
million or 42 percent from 1994. LOE, excluding severance taxes, totaled $181.1
million, an increase of $55.8 million from 1994. On an equivalent unit of
production basis, LOE for the year ended December 31, 1995, averaged $3.34 per
boe, a
 
                                       19
   22
 
17 percent increase from $2.85 per boe in 1994. The increase in unit cost
reflects the high percentage of oil properties comprising the Texaco
acquisition, as oil properties typically have a higher per-unit cost than gas
properties.
 
     Administrative, selling and other costs in 1995 decreased $2.2 million, or
six percent, due primarily to the elimination of duplicate administrative
functions following the merger of DEKALB into Apache. On an equivalent unit of
production basis, general and administrative expenses declined 24 percent from
1994 to $.67 per boe.
 
     Net financing costs of $70.6 million were more than double the 1994 amount
due to increased debt levels from acquisitions and higher interest rates.
Apache's average interest rate increased from 6.3 percent in 1994 to 7.4 percent
in 1995 due to higher market rates and Apache's higher debt to total
capitalization rate following the acquisition of properties from Texaco.
 
CASH FLOW, LIQUIDITY AND CAPITAL RESOURCES
 
CAPITAL COMMITMENTS
 
     Apache's primary needs for cash are for exploration, development and
acquisition of oil and gas properties, repayment of principal and interest on
outstanding debt, payment of dividends, and capital obligations for affiliated
ventures. The Company generally funds its exploration and development activities
through internally generated cash flows. Apache budgets its capital expenditures
based upon projected cash flows and routinely adjusts its capital expenditures
in response to changes in oil and natural gas prices and corresponding changes
in cash flow. The Company is not in a position to predict future product prices.
 
     Capital Expenditures -- A summary of oil and gas capital expenditures over
the last three years is presented below:
 


                                             1996         1995         1994

Acquisitions of Oil and Gas Properties...  $446,205     $820,918     $180,742
                                           ========     ========     ========

 
     Expenditures for exploration and development totaled $493.7 million in 1996
compared to $312.2 million in 1995. Apache's drilling program in 1996 added 98
MMboe of reserves (including revisions), replacing 179 percent of production. In
the United States, Apache completed 229 gross wells as producers out of 293
gross wells drilled during the year, compared with 138 gross producers out of
174 gross wells drilled in 1995. In Canada, Apache completed 50 gross wells as
producers out of 77 gross wells drilled during the year, compared with 30 gross
producers out of 48 gross wells drilled in 1995.
 
     Internationally, the Company completed 24 gross producers of 36 gross wells
drilled in 1996, compared to 12 gross producers out of 26 gross wells in 1995.
The international wells drilled in 1996 included 19 successful wells in Egypt
and five successful wells in Australia.
 
     United States and Canadian expenditures for exploration and development in
1997 operations, are expected to exceed the 1996 expenditures by approximately
$60 million. The Company expects its other international exploration and
development expenditures in 1997, exclusive of facilities, to total
approximately $220 million.
 
     Acquisition costs of oil and gas properties, including the value assigned
to shares issued and issuable and liabilities assumed in the Phoenix merger,
totaled $446.2 million in 1996 compared to $820.9 million in 1995.
 
                                       20
   23
 
Property acquired in the Phoenix merger totaled $386.2 million of which $331.2
million related to oil and gas properties and $55.0 million to facilities.
Apache also acquired $115.0 million of other oil and gas properties during 1996,
primarily representing tactical acquisitions of properties in the Company's
existing focus areas, including the purchase of certain oil and gas properties
from Hall-Houston for $46 million in cash. Funds for the acquisitions were
obtained principally from borrowings under the Company's revolving bank credit
facilities.
 
     Cash expenditures for acquisitions of oil and gas properties during 1995
totaled $820.9 million as the Company added 156 MMboe of oil and gas reserves
through purchases. The most significant of the 59 transactions Apache completed
during 1995 were the Company's acquisitions of properties from Texaco and
Aquila.
 
     On March 1, 1995, Apache purchased certain United States oil and gas
properties from Texaco for approximately $567 million in cash, subject to
adjustment. Funds for the Texaco transaction were obtained from several sources,
including increased borrowing capacity under the Company's revolving bank credit
facility and proceeds of Apache's $172.5 million 6 percent Convertible
Subordinated Debentures due 2002 (6 percent debentures), which were issued on
January 4, 1995.
 
     In September 1995, Apache acquired the Aquila Assets for approximately $210
million. The oil and gas properties included approximately 107,000 developed and
49,000 undeveloped net acres located primarily in Apache's Anadarko Basin and
Gulf of Mexico core areas. Also included in the transaction was the purchase of
a five-year, four-month premium-price gas contract and interests in four gas
processing plants.
 
     Cash expenditures for 1994 acquisitions, excluding AERC, totaled $180.7
million. The most significant acquisition that Apache closed during 1994 was the
purchase of substantially all of the United States oil and gas properties of
Crystal Oil Company for $95.8 million. Apache also acquired approximately $84.9
million of other oil and gas properties through a number of separate
transactions during 1994. Funds for the 1994 acquisitions were obtained
principally from borrowings under the Company's revolving bank credit facility.
 
     Debt and Interest Commitments -- At December 31, 1996, Apache had
outstanding debt of $376.5 million under its global credit facility and an
aggregate of $861.2 million of other debt, comprised principally of notes and
debentures maturing in the years 1997 through 2096. Debt outstanding at December
31, 1996 of $1.2 billion was up 15 percent over the $1.1 billion outstanding at
December 31, 1995. The increase reflects the Phoenix Merger and other 1996
property acquisitions. Although debt increased, the Company's debt-to-
capitalization ratio decreased from 49.6 percent at December 31, 1995 to 44.9
percent at December 31, 1996.
 
     During 1996, the Company significantly extended maturity dates of its
long-term debt with long-term offerings and reduced outstanding balances of its
shorter-term, variable-rate debt. In February, Apache issued $100 million
principal amount of 7.7 percent notes due 2026. In April, $180 million principal
amount of 7.95 percent notes due 2026 was issued and, in November, Apache
completed the issuance of 7.625 percent debentures due 2096 for a principal
amount of $150 million. Interest payments on the Company's outstanding debt
obligations during 1997 are projected (using weighted average balances for
floating rate obligations) to be approximately $99.5 million, while scheduled
principal payments for 1997 total $77 million. However, the $75 million
principal amount of 3.93 percent convertible notes due in November 1997 is not
reflected as current maturities in the Company's consolidated balance sheet, as
such notes are expected to be refinanced with long-term debt if not converted
into Apache common stock.
 
     Dividend Payments -- Dividends paid during 1996 totaled $23.4 million, up
24 percent from 1995, primarily due to the issuance of 12.2 million shares of
Apache common stock in connection with the May 1996 acquisition of Phoenix. The
Company has paid cash dividends on its common stock for 120 consecutive quarters
through December 31, 1996, and expects to continue payment of dividends at
current levels, although future dividend payments will depend on the Company's
level of earnings, financial requirements and other relevant factors.

CAPITAL RESOURCES AND LIQUIDITY
 
     The Company's primary capital resources are net cash provided by operating
activities, proceeds from financing activities and proceeds from sales of
non-strategic assets.
 
     Net Cash Provided by Operating Activities -- Apache's net cash provided by
operating activities during 1996 totaled $490.5 million, an increase of 48
percent from the $332.1 million provided in 1995. This increase was due
primarily to higher product prices during 1996. Net cash provided by operating
activities in 1995 was down $25.6 million from 1994 primarily due to the
prior-year amounts including a $67.4 million advance of future gas deliveries.
 
     Long-Term Borrowings -- During February 1996, Apache completed the issuance
of $100 million principal amount, $99.6 million after discount, of senior
unsecured 7.7 percent notes due March 15, 2026. In April 1996, the Company
issued $180 million principal amount, $178.5 million net of discount, of senior
unsecured 7.95 percent notes due on April 15, 2026. In November 1996, Apache
completed the issuance of $150 million, $149.2 million after discount, of senior
unsecured 7.625 percent debentures due November 1, 2096. The proceeds from these
issuances were used to repay a portion of the Company's revolving bank credit
facility and for general corporate purposes.
 
     The offerings of the two 30-year notes and the 100-year debentures were
placed during periods when 30-year interest rates on Treasury bonds were near
historic 20-year lows. Further, the 100-year debentures were issued following
recent upgrades of the Company's long-term debt ratings which resulted in a
significant narrowing in the spread over the Treasury bond yields. In addition
to the benefits of securing longer-term financing at favorable interest rates
and reducing Apache's exposure to future adverse interest rate fluctuations, the
issuance of the 30-year notes improved the Company's liquidity as the borrowing
base under the Company's global credit facility was reduced by an amount less
than the net proceeds received from issuing the notes.
 
     On October 31, 1996, Apache replaced its existing $1 billion revolving bank
credit facility with a global credit facility that provides Apache with greater
borrowing availability, increased tax efficiency and a lower cost of bank debt.
Consisting of three separate bank facilities tied together by an intercreditor
agreement, the new global credit facility adds Apache's oil and gas reserve
values in Australia and Canada to those in the United States in determining the
Company's borrowing capacity. The facilities consist of $125 million of credit
commitments each in Australia and Canada, and a $750 million credit commitment
in the United States. In connection with securing the global credit facility,
the Company repaid certain of its subsidiary debt, including DEKALB's 10 percent
notes, the Apache Canada Ltd. facility (the Bank of Montreal facility) and the
AEL acceptance facility, all of which had higher interest rates than those under
the global credit facility. As of December 31, 1996, Apache's borrowing base
under the global credit facility was $947 million, of which defined borrowing
base debt was $733 million, leaving $214 million available for additional
borrowings.
 
     During September 1996, Moody's Investor's Service upgraded the Company's
senior long-term debt rating from Baa3 to Baa1. Historically, such a two-notch
rating improvement for an existing investment grade company is uncommon. In
addition, Apache's subordinated debt rating was raised three levels, to Baa2
from Ba2. According to Moody's, the upgrade was the result of several recent
developments, including the Company's lower debt-to-equity ratio, higher
earnings and cash flow, lower interest expense, successful expansion in Egypt
and Western Australia, and a shift in the Company's strategy toward growing
reserves and production primarily through drilling. Also in September 1996,
Standard & Poor's revised its outlook to "positive" from "stable" on Apache's
long-term debt. Standard & Poor's subsequently upgraded the Company's senior
long-term debt from BBB to BBB+ and subordinated debt from BBB- to BBB in
January 1997.
 
     In October 1996, Duff & Phelps Credit Rating Co. upgraded the Company's
senior long-term debt from BBB+ to A-, its 6 percent subordinated debentures
from BBB to BBB+, and its commercial paper from D-2 to D-1-(D-One-Minus).
 
                                       22
   25
 
     In January 1997, the Company established a $300 million commercial paper
program. The program allows Apache to borrow funds for up to 270 days at
attractive interest rates. The commercial paper program is supported by
availability under the $750 million United States portion of the global credit
facility.
 
     Stock Transactions -- On May 20, 1996, Apache acquired Phoenix. Pursuant to
the Merger Agreement, each share of Phoenix common stock then outstanding, and
outstanding Phoenix stock options (which were assumed by Apache) were converted
into the right to receive (a) .75 shares of Apache common stock with any
fractional shares paid in cash, without interest, and (b) $4.00 in cash. As a
result, 12.2 million shares of Apache common stock, valued at $26.00 per share,
were issued in exchange for outstanding Phoenix stock with an additional .8
million shares issuable under options assumed.
 
     On September 27, 1995, Apache closed an equity offering of 7.45 million
shares of Apache common stock. Net proceeds of approximately $195.5 million were
used to repay existing indebtedness under the Company's revolving bank credit
facility, to finance the Aquila transaction and for general corporate purposes.
 
     Asset Sales -- During 1996, Apache received $30.1 million from the sale of
non-strategic oil and gas properties in a number of separate transactions. In
early 1995, Apache announced plans to accelerate the disposition of lower-margin
and non-strategic properties, including the sale of a substantial portion of its
Rocky Mountain properties. During 1995, Apache received $271.9 million from the
sale of such properties, utilizing the proceeds to reduce bank debt. Apache
received $19.5 million from the sale of non-strategic oil and gas properties
during 1994.
 
     Liquidity -- The Company had $13.2 million in cash and cash equivalents on
hand at December 31, 1996, down slightly from the $13.6 million at December 31,
1995. Apache's ratio of current assets to current liabilities decreased slightly
from .90:1 at December 31, 1995, to .87:1 at December 31, 1996.
 
     Management believes that cash on hand, net cash generated from operations
and unused committed borrowing capacity under its global credit facility will be
adequate to satisfy the Company's financial obligations to meet future liquidity
needs for at least the next two fiscal years.
 
FUTURE TRENDS
 
     Apache's growth strategy is to increase oil and gas reserves, production,
and cash flow through a combination of exploratory drilling, development of its
inventory of existing projects and, principally in North America, tactical
acquisitions meeting defined financial parameters. The Company's drilling
program emphasizes reserve additions through exploratory drilling primarily on
its international interests, and moderate-risk drilling primarily on its North
American interests. The Company also emphasizes reducing operating costs per
unit produced and selling marginal and non-strategic properties in order to
increase its profit margins.
 
     Apache's international investments and exploration activities are an
important component of its long-term growth strategy. Although international
exploration is recognized as higher-risk than most of Apache's U.S. and Canadian
activities, it offers potential for greater rewards and significant reserve
additions. Apache directed its international efforts in 1996 toward development
of certain discoveries offshore Western Australia and in Egypt, and toward
further exploration efforts on its concessions in Egypt, offshore The People's
Republic of China, in Indonesia and offshore the Ivory Coast of western Africa.
Apache believes that reserve additions in these international areas may be made
through higher-risk exploration and through improved production practices and
recovery techniques.
 
     For Apache, property acquisition is only one phase in a continuing cycle of
business growth. Apache's aim is to follow each acquisition with a cycle of
reserve enhancement, property consolidation and cash flow acceleration,
facilitating asset growth and debt reduction. This approach requires a
well-planned and carefully executed property development program and, where
appropriate, a selective program of property dispositions. It motivates Apache
to target acquisitions that have ascertainable additional reserve potential and
to apply an active drilling, workover and recompletion program to realize the
potential of the acquired undeveloped and partially developed properties. Apache
prefers to operate its properties so that it can best influence their
development; as a result, the Company operates properties accounting for over 75
percent of its production.
 
                                       23
   26
 
     In 1997, Apache expects North American exploration and development outlays
to increase from 1996 levels as the Company focuses on increasing reserves,
production and cash flow through exploratory drilling and development of its
existing inventory. Internationally, the Company projects capital expenditures
to nearly double from 1996 as Apache continues to exploit its concessions in
Egypt, Western Australia, China and Indonesia. Proposed exploration and
development expenditures in 1997 will be reviewed at least every quarter in
light of fluctuating product prices and Apache's objective to fund operations
through internally generated cash flow.
 
     On October 31, 1996, subject to shareholder approval, Apache's Board of
Directors adopted the 1996 Share Price Appreciation Plan for officers and
certain key employees. The plan provides for awards denominated in shares of
Apache common stock to become payable upon attainment of share price goals of
$50 and $60 per share, respectively, before January 1, 2000. Between 30 and 50
percent of the number of shares awarded will be paid in cash at the market value
of the stock on the date of payments, and the balance (up to a total of
2,000,000 shares in the aggregate) will be issued in Apache common stock.
Generally, any payments will be made in three installments over 36 months. When
and if payments are made, the Company will recognize compensation expense over
the 36 month vesting period equal to the value of the stock issued on the date
the share price goal is attained (i.e., $50 or $60, as appropriate) and the
actual amount of cash paid.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO THE SHAREHOLDERS OF APACHE CORPORATION:
 
     We have audited the accompanying consolidated balance sheet of Apache
Corporation (a Delaware corporation) and Subsidiaries as of December 31, 1996
and 1995, and the related statements of consolidated income, shareholders'
equity, and cash flows for each of the three years in the period ended December
31, 1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits. We did not audit the financial statements of
DEKALB Energy Company, a company acquired during 1995 in a transaction accounted
for as a pooling of interests, for the year ended December 31, 1994, as
discussed in Note 2. Such financial statements are included in the consolidated
financial statements of Apache Corporation and Subsidiaries and reflect total
revenues of eight percent of the related consolidated total for the year ended
December 31, 1994, after restatement to reflect certain adjustments as set forth
in Note 2. The financial statements of DEKALB Energy Company, prior to those
adjustments, were audited by other auditors whose report has been furnished to
us and our opinion, insofar as it relates to 1994 amounts included for DEKALB
Energy Company, is based solely upon the report of the other auditors.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits, and the report of other auditors, provide a
reasonable basis for our opinion.
 
     In our opinion, based on our audits and the report of other auditors, the
consolidated financial statements referred to above present fairly, in all
material respects, the financial position of Apache Corporation and Subsidiaries
as of December 31, 1996 and 1995, and the results of their operations and their
cash flows for each of the three years in the period ended December 31, 1996, in
conformity with generally accepted accounting principles.

                                AUDITORS' REPORT
 
TO THE SHAREHOLDERS AND BOARD OF DIRECTORS OF DEKALB ENERGY COMPANY:
 
     We have audited the consolidated balance sheet of DEKALB Energy Company as
at December 31, 1994 and the consolidated statements of operations,
shareholders' equity and cash flows for the year ended December 31, 1994. These
consolidated financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.
 
     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform an audit to obtain
reasonable assurance whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
 
     In our opinion, these consolidated financial statements present fairly, in
all material respects, the consolidated financial position of DEKALB Energy
Company as at December 31, 1994 and the consolidated results of its operations
and its cash flows for the year ended December 31, 1994, in accordance with
United States generally accepted accounting principles.

                              REPORT OF MANAGEMENT
 
     The financial statements and related financial information of Apache
Corporation and Subsidiaries were prepared by and are the responsibility of
management. The statements have been prepared in conformity with generally
accepted accounting principles and include amounts that are based on
management's best estimates and judgments.
 
     Management maintains and places reliance on systems of internal control
designed to provide reasonable assurance, weighing the costs with the benefits
sought, that all transactions are properly recorded in the Company's books and
records, that policies and procedures are adhered to, and that assets are
safeguarded. The systems of internal controls are supported by written policies
and guidelines, internal audits and the selection and training of qualified
personnel.
 
     The financial statements of Apache Corporation and Subsidiaries, except for
DEKALB Energy Company prior to 1995, have been audited by Arthur Andersen LLP,
independent public accountants. The financial statements of DEKALB Energy
Company and its subsidiaries for 1994 were audited by Coopers & Lybrand. Their
audits included developing an overall understanding of each Company's accounting
systems, procedures and internal controls and conducting tests and other
auditing procedures sufficient to support their opinions on the fairness of the
respective consolidated financial statements.
 
     The Apache Corporation Board of Directors exercises its oversight
responsibility for the financial statements through its Audit Committee,
composed solely of directors who are not current or former employees of Apache.
The Audit Committee meets periodically with management, internal auditors and
the independent public accountants to ensure that they are successfully
completing designated responsibilities. The internal auditors and independent
public accountants have open access to the Audit Committee to discuss auditing
and financial reporting issues.

Internationally, Apache has exploration and production interests offshore
Western Australia and in Egypt, and exploration interests offshore The People's
Republic of China, in Indonesia and offshore the Ivory Coast. Apache treats all
operations as one segment of business.
 
     The Company's future financial condition and results of operations will
depend upon prices received for its oil and natural gas production and the costs
of finding, acquiring, developing and producing reserves. A substantial portion
of the Company's production is sold under market-sensitive contracts. Prices for
oil and natural gas are subject to fluctuations in response to changes in
supply, market uncertainty and a variety of other factors beyond the Company's
control. These factors include worldwide political instability (especially in
the Middle East), the foreign supply of oil and natural gas, the price of
foreign imports, the level of consumer demand, and the price and availability of
alternative fuels. With natural gas accounting for 63 percent of Apache's 1996
production on an energy equivalent basis, the Company was affected more by
fluctuations in natural gas prices than in oil prices.
 
     Principles of Consolidation -- The accompanying consolidated financial
statements include the accounts of Apache and its subsidiaries after elimination
of intercompany balances and transactions. The Company's interests in oil and
gas ventures and partnerships are proportionately consolidated. Certain
reclassifications have been made to the Consolidated Financial Statements for
prior years to conform with the current presentation. Apache's investment in
Producers Energy Marketing LLC (ProEnergy), a jointly-owned marketing company,
is accounted for using the equity method.
 
     Cash Equivalents -- The Company considers all highly liquid debt
instruments purchased with an original maturity of three months or less to be
cash equivalents. These investments are carried at cost, which approximates
market.
 
     Inventories -- Inventories consist principally of tubular goods and
production equipment, stated at the lower of weighted average cost or market,
and oil produced but not sold, stated at current market value net of costs to
sell.
 
     Property and Equipment -- The Company uses the full cost method of
accounting for its investment in oil and gas properties. Under this method, the
Company capitalizes all acquisition, exploration and development costs incurred
for the purpose of finding oil and gas reserves, including salaries, benefits
and other internal costs directly attributable to these activities. Exclusive of
field-level costs, Apache capitalized $12.8 million, $12.5 million and $14.6
million of internal costs in 1996, 1995 and 1994, respectively. Costs associated
with production and general corporate activities are expensed in the period
incurred. Internal costs attributable to the management of the Company's
producing properties, before recoveries from industry partners, totaled $17.0
million, $16.3 million and $13.2 million in 1996, 1995, and 1994, respectively,
and are included in operating costs in the Company's Statement of Consolidated
Income. Interest costs related to unproved properties and properties under
development are also capitalized to oil and gas properties. Unless a significant
portion of the Company's reserve volumes are sold (greater than 25 percent),
proceeds from the sale of oil and gas properties are accounted for as reductions
to capitalized costs, and gains or losses are not recognized.
 
     Apache computes the provision for depreciation, depletion and amortization
(DD&A) of oil and gas properties on a quarterly basis using the
unit-of-production method based upon production and estimates of proved reserve
quantities. Unevaluated costs and related capitalized interest costs are
excluded from the
 
                                       F-8

                      APACHE CORPORATION AND SUBSIDIARIES
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
amortization base until the properties associated with these costs are
evaluated. The amortizable base includes estimated future development costs and
dismantlement, restoration and abandonment costs, net of estimated salvage
values. These future costs are generally estimated by engineers employed by
Apache.
 
     Apache limits, on a country-by-country basis, the capitalized costs of
proved oil and gas properties, net of accumulated DD&A, to the estimated future
net cash flows from proved oil and gas reserves, net of related tax effects,
discounted at 10 percent. If capitalized costs exceed this limit, the excess is
charged to DD&A expense. Included in the estimated future net cash flows are
Canadian provincial tax credits expected to be realized beyond the date at which
the legislation, under its provisions, could be repealed. To date, the Canadian
provincial government has not indicated an intention to repeal this legislation.
 
     The costs of certain unevaluated leasehold acreage, wells being drilled and
international concession rights are not being amortized. Costs not being
amortized are periodically assessed for possible impairments or reductions in
value. If a reduction in value has occurred, costs being amortized are increased
or a charge is made against earnings for those international operations where a
reserve base is not yet established.
 
     Buildings, equipment and gas gathering, transmission and processing
facilities are depreciated on a straight-line basis over the estimated useful
lives of the assets, which range from two to 20 years. Accumulated depreciation
for these assets totaled $36.6 million and $26.3 million at December 31, 1996
and 1995, respectively.
 
     Accounts Payable -- Included in accounts payable at December 31, 1996 and
1995, are liabilities of approximately $36.5 million and $48 million,
respectively, representing the amount by which checks issued, but not presented
to the Company's banks for collection, exceeded balances in applicable bank
accounts.
 
     Revenue Recognition -- Apache uses the sales method of accounting for
natural gas revenues. Under this method, revenues are recognized based on actual
volumes of gas sold to purchasers. The volumes of gas sold may differ from the
volumes to which Apache is entitled based on its interests in the properties.
Differences between volumes sold and volumes based on entitlements create gas
imbalances which are generally reflected as adjustments to reported gas reserves
and future cash flows in the Company's supplemental oil and gas disclosures.
Adjustments for gas imbalances totaled less than one percent of Apache's proved
gas reserves at December 31, 1996. Revenue is deferred and a liability is
recorded for those properties where the estimated remaining reserves will not be
sufficient to enable the underproduced owner to recoup its entitled share
through production.
 
     Hedging Activities -- Apache periodically enters into commodity derivatives
contracts and fixed-price physical contracts to manage its exposure to oil and
gas price volatility. Commodity derivatives contracts, which are usually placed
with major financial institutions that the Company believes are minimal credit
risks, may take the form of futures contracts, swaps or options. Realized gains
and losses from the Company's price risk management activities are recognized in
oil and gas production revenues when the associated production occurs. Estimates
of future cash flows related to derivatives contracts, based upon year-end
prices, and fixed-price physical contracts are reflected in future cash inflows
from proved reserves in the Company's supplemental oil and gas disclosures.
 
     The Company enters into various interest rate cap and swap agreements from
time to time with major financial institutions to manage its exposure to
fluctuations in market interest rates. Gains and losses on these activities are
recognized in interest expense in the period hedged by the agreements.
 
     Income Taxes -- The Company follows the liability method of accounting for
income taxes under which deferred tax assets and liabilities are recognized for
the future tax consequences of (i) temporary differences between the tax bases
of assets and liabilities and their reported amounts in the financial statements
and (ii) operating loss and tax credit carryforwards for tax purposes. Deferred
tax assets are reduced by a valuation

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
allowance when, based upon management's estimates, it is more likely than not
that a portion of the deferred tax assets will not be realized in a future
period.
 
     Foreign Currency Translation -- The U.S. dollar is considered the
functional currency for each of the Company's international operations, except
for the Canadian subsidiary whose functional currency is the Canadian dollar.
Translation adjustments resulting from translating the Canadian subsidiary's
foreign currency financial statements into U.S. dollar equivalents are reported
separately and accumulated in a separate component of shareholders' equity. For
other international operations, transaction gains or losses are recognized in
current net income and were not material in any of the periods presented.
 
     Net Income Per Common Share -- Amounts are based on the weighted average
number of shares of common stock outstanding. The effects of common stock
equivalents, which would include shares from the assumed conversion of the 3.93
percent notes, were either immaterial or not dilutive for each of the periods
presented. Furthermore, fully diluted net income per share, assuming conversion
of certain of the convertible debentures, was not significantly different than
primary net income per share for all periods presented.
 
     Stock-Based Compensation -- The Company accounts for employee stock-based
compensation using the intrinsic value method prescribed by Accounting
Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued to
Employees" and related Interpretations. Accordingly, the issuance by the
Financial Accounting Standards Board of Statement of Financial Accounting
Standards (SFAS) No. 123, "Accounting for Stock-Based Compensation" in 1996 had
no effect on the Company's results of operations.
 
     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
Significant estimates with regard to these financial statements include the
estimate of proved oil and gas reserve volumes and the related present value of
estimated future net revenues therefrom (see supplemental oil and gas
disclosures).
 
2. ACQUISITIONS AND DIVESTITURES
 
ACQUISITIONS
 
     On May 20, 1996, Apache acquired, for approximately $396.3 million, The
Phoenix Resource Companies, Inc. (Phoenix), an oil and gas company operating
primarily in the Arab Republic of Egypt, through a merger (Merger) which
resulted in Phoenix becoming a wholly-owned subsidiary of Apache. Pursuant to
the Merger Agreement, shares of Phoenix common stock then outstanding and
outstanding Phoenix stock options (which were assumed by Apache) were converted
into the right to receive (a) .75 shares of Apache common stock with any
fractional shares paid in cash, without interest, and (b) $4.00 in cash. As a
result, 12.2 million shares of Apache common stock, valued at $26 per share,
were issued and approximately $65 million was paid to former Phoenix
shareholders.
 
     In 1996, the Company also completed 62 tactical regional acquisitions for
cash consideration totaling $115.0 million. These acquisitions added
approximately 18.9 MMboe to the Company's reserves.
 
     In September 1995, Apache acquired substantially all of the oil and gas
assets of Aquila Energy Resources Corporation (Aquila) for approximately $210
million. The acquired assets included proved reserves totaling an estimated 157
Bcf of gas equivalent, approximately 107,000 developed and 49,000 undeveloped
net acres located primarily in Apache's Anadarko Basin and Gulf of Mexico core
areas, a five-year, four-month premium-price gas contract effective September 1,
1995, and non-operated interests in four gas processing plants. The gas contract
calls for Aquila Energy Marketing Corporation, a wholly owned subsidiary of

UtiliCorp United Inc., to purchase 20 to 25 MMcf of gas per day from Apache at a
price of $2.70 per Mcf in 1996, escalating to $3.20 per Mcf in the year 2000.
 
     On May 17, 1995, Apache acquired DEKALB Energy Company (DEKALB, now known
as DEK Energy Company), an oil and gas company engaged in the exploration for,
and the development of, crude oil and natural gas in Canada, through a merger
which resulted in DEKALB becoming a wholly owned subsidiary of Apache. Pursuant
to the merger agreement, 8.4 million shares of Apache common stock were
exchanged for the outstanding DEKALB stock and DEKALB employee stock options.
Merger costs of approximately $10 million were charged to expense in the second
quarter of 1995. The merger was accounted for as a "pooling of interests" and,
as a result, the Company's consolidated financial statements for periods prior
to the merger have been restated to include combined results with DEKALB.
 
     In connection with the DEKALB merger, the methods used by Apache and DEKALB
in computing DD&A expense of proved oil and gas properties were conformed to the
units-of-production method using physical units. This method was previously used
by DEKALB and in conforming the methods used, Apache adopted the
units-of-production method in lieu of the future gross revenue method. The
conforming adjustments for DD&A expense have been reflected retroactively in the
accompanying consolidated financial statements along with an adjustment to
DEKALB's previously recorded deferred tax valuation allowance for U.S. operating
loss carryforwards expected to be utilized by Apache in future periods. All
other adjustments are reclassifications to conform financial statement
presentation. Apache and DEKALB had no significant intercompany transactions
prior to the merger.
 
     A reconciliation of the previously separate results of Apache and DEKALB to
the restated combined results for 1994 is as follows:

     On March 1, 1995, Apache completed the acquisition of 315 oil and gas
fields from Texaco Exploration and Production Inc. (Texaco) for an adjusted
purchase price of $567 million. The Texaco properties included estimated proved
reserves at the effective date, after adjustment for the exercise of
preferential rights and properties excluded following due diligence, of
approximately 105 MMboe.
 
     In December 1994, Apache purchased substantially all of the U.S. oil and
gas properties of Crystal Oil Company (Crystal) for approximately $95.8 million.
The producing oil and gas properties acquired from Crystal are located primarily
along the Arkansas-Louisiana border and southern Louisiana. The acquisition also
included approximately 32,000 net undeveloped mineral acres in southern
Louisiana.
 
     Except for the DEKALB transaction, each transaction described above has
been accounted for using the purchase method of accounting and has been included
in the financial statements of Apache since the dates of acquisition.

DIVESTITURES
 
     In 1996, Apache received $30.1 million from the sale of non-strategic oil
and gas properties in a number of separate transactions.
 
     In September 1995, Apache closed the sale of non-strategic oil and gas
properties in its Rocky Mountain region for approximately $140 million net to
Apache. The assets included Apache's interests in 138 fields with approximately
1,600 active wells in Colorado, Montana, North and South Dakota, Utah and
Wyoming. The Company retained its interests in the Green River Basin of Colorado
and Wyoming and in the San Juan Basin of Colorado and New Mexico. Proceeds from
the sale of all oil and gas properties sold during 1995 totaled $271.9 million.
 
3. INVESTMENTS IN EQUITY SECURITIES
 
     At December 31, 1996, Apache had no investments in equity securities.
 
     The Company realized gross gains totaling $.8 million, $.9 million and $2.2
million from the sale of equity securities during 1996, 1995 and 1994,
respectively. Apache utilizes the average cost method in computing realized
gains or losses, which are included in other revenues in the accompanying

     On October 31, 1996, Apache replaced its existing $1 billion revolving bank
credit facility with a global credit arrangement (global credit facility) that
provides Apache with greater borrowing availability, increased tax efficiency
and a lower cost of bank debt. Consisting of three separate bank facilities tied
together by an intercreditor agreement, the new global credit facility adds
Apache's oil and gas reserve values in Australia and Canada to those in the U.S.
in determining the Company's borrowing capacity. The facilities consist of a
$125 million facility in each of Australia and Canada, and a $750 million
facility in the United States. In connection with securing the global credit
facility, the Company terminated the AEL acceptance facility and the Bank of
Montreal facility using funds available under the new facility. The maximum
amount available is subject to periodic redetermination of a borrowing base,
determined solely at the discretion of the banks, predicated upon the Company's
oil and gas reserve values and forecast rate of production. As of December 31,
1996, the borrowing base was $947 million and, adjusted for certain specified
debt balances totaling $733 million, the available borrowing capacity under its
global credit facility totaled $214 million. Under the terms of the global
credit facility as of December 31, 1996, the Company must (i) maintain a minimum
tangible net worth of $880 million, which is adjusted quarterly for subsequent
earnings and securities transactions, and (ii) maintain a ratio of (a) earnings
before interest, taxes, depreciation, depletion and

Company was in compliance with all financial covenants at December 31, 1996.
 
     The global credit facility is scheduled to mature on October 31, 2001, and
the agreement provides for perpetual one-year extensions as requested by the
Company, subject to the approval of the lenders. At the Company's option, the
interest rate is based on (i) the First National Bank of Chicago's base rate,
(ii) the London Interbank Offered Rate (LIBOR) plus a margin determined by the
Company's senior debt rating and its ratio of debt to total capitalization, or
(iii) the LIBOR rate plus a margin that is determined by competitive bids from
the participating banks. At December 31, 1996, the margin for committed loans
was .25 percent. The Company also pays an annual facility fee of .10 percent on
the total amount of each of the three facilities, which varies based upon the
Company's public senior debt rating.
 
     In November 1996, Apache issued $150 million principal amount, $149.2
million net of discount, of senior unsecured 7.625 percent debentures maturing
on November 1, 2096. The debentures are not redeemable prior to maturity.
However, Apache has the right to advance maturity, under certain conditions.
These debentures are governed by the same indenture that governs the Company's
two issues of 30 year notes.
 
     During February 1996, Apache issued $100 million principal amount, $99.6
million net of discount, of senior unsecured 7.7 percent notes due March 15,
2026. During April 1996, Apache issued an additional $180 million principal
amount, $178.5 million net of discount, of senior unsecured 7.95 percent notes
maturing on April 15, 2026. Neither issue of notes is redeemable prior to
maturity. The indenture governing the notes imposes certain restrictions on the
Company, including limits on Apache's ability to incur debt secured by certain
liens and its ability to enter into certain sale and leaseback transactions.
 
     The 6 percent convertible subordinated debentures due 2002 totaling $172.5
million were issued by Apache in January 1995 and are convertible at the option
of the holder into Apache common stock at a price of $30.68 per share, subject
to adjustment under certain circumstances.
 
     The 9.25 percent notes totaling $100 million were issued by Apache in May
1992 and are not redeemable prior to their maturity in June 2002. In December
1992, Apache issued the 3.93 percent convertible notes. The 3.93 percent notes
mature in November 1997, and are not redeemable prior to maturity; however, they
are convertible into Apache common stock at $27 per share, subject to adjustment
under certain circumstances. The 3.93 percent notes are classified as long-term
debt in the accompanying consolidated balance sheet, as the Company has the
ability and intent to replace them with additional long-term debt if they are
not converted into Apache common stock.
 
     The indentures for the 9.25 percent and 3.93 percent notes impose
substantially similar restrictions on the Company, including limits on the
Company's ability to incur debt secured by certain liens and on its ability to
enter into certain sale and leaseback transactions. Upon certain changes in
control of the Company, both issues are subject to mandatory repurchase (or
conversion at the option of the noteholders in the case of the 3.93 percent
notes).
 
     At December 31, 1996, the Company also had certain uncommitted money market
lines of credit which are used from time to time for working capital purposes.
As of December 31, 1996, an aggregate of $2 million was outstanding under such
credit lines.
 
     The DEKALB 9.875 percent notes mature on July 15, 2000. On October 25,
1996, Apache redeemed, at par, $22.1 million principal amount of DEKALB 10
percent notes. Such notes were due in 1998 and were redeemed using borrowings
under the Company's revolving bank credit facility.
 
     In 1996, the Company, acting through two of its Egyptian subsidiaries,
established $75 million of secured credit facilities with the International
Finance Corporation to finance development of its Qarun Concession in Egypt.
During the pre-completion phase of development operations, the Company
guarantees the credit facilities; following completion, the facilities are
secured only by assets associated with the Qarun Concession.

Interest is assessed at LIBOR plus a margin determined by several factors,
including the Company's public senior debt ratings, the Company's
debt-to-capitalization ratio, and whether or not development operations are in
the pre-completion phase. At December 31, 1996, outstanding borrowings under
these facilities totaled $54.75 million and the applicable margin over LIBOR was
..875 percent. A commitment fee equal to one-half of one percent per annum is
payable on the unused portion of the facilities. Repayment of amounts
outstanding under the facilities is contractually scheduled to commence on June
15, 1998, with semi-annual installments thereafter ending on December 15, 2002.
 
     In 1992, Apache established a $35 million banking facility on behalf of
Apache Offshore Investment Partnership. At December 31, 1996, the amount
outstanding under such facility was $2.35 million, of which Apache's share was
$.6 million. On January 31, 1997, the loan was repaid by the Partnership and the
facility terminated.
 
     As of December 31, 1996 and 1995, the Company had approximately $20.3
million and $19.3 million, respectively, of unamortized costs associated with
its various debt obligations. These costs are reflected as deferred charges in
the accompanying consolidated balance sheet and are being amortized over the
life of the related debt.
 
     In January 1997, the Company established a $300 million commercial paper
program. The program allows Apache to borrow funds for up to 270 days at
attractive interest rates. The commercial paper program is supported by
availability under the $750 million U.S. portion of the global credit facility.

     U.S. deferred taxes have not been provided on foreign earnings totaling
$104 million, which are permanently reinvested abroad. Presently, limited
foreign tax credits are available to reduce the U.S. taxes on such amounts if
repatriated.
 
     At December 31, 1996, the Company had U.S. Federal net operating loss
carryforwards of $179.1 million that will expire beginning in 1997, foreign net
operating loss carryforwards of $6.5 million that can be carried forward
indefinitely, and U.S. and foreign statutory depletion carryforwards totaling
$13.4 million that can be carried forward indefinitely. The Company has
alternative minimum tax (AMT) credit carryforwards of $9.1 million that can be
carried forward indefinitely but which can be used only to reduce regular tax
liabilities in excess of AMT liabilities. The Company has investment and other
tax credit carryforwards of $.9 million that will expire beginning in 1997,
which have been fully reserved through the valuation allowance.
 
6. ADVANCE FROM GAS PURCHASER
 
     In December 1994, Apache received $67.4 million from a purchaser as an
advance payment for future natural gas deliveries of 20,000 MMBtu per day over a
six-year period commencing January 1995. As a condition of the arrangement with
the purchaser, Apache entered into a gas price swap contract with a third party
under which Apache became a fixed price payor at identical volumes and at prices
starting at $1.81 per MMBtu in 1995 and escalating at $.10 per MMBtu per year
through the year 2000. The net result of these related transactions is that gas
delivered to the purchaser will be reported as revenue at prevailing spot prices
in the future with Apache realizing a $.05 per MMBtu premium associated with a
monthly fee to be paid by the purchaser. The Company, through its marketing
subsidiaries, may purchase gas from third parties to satisfy gas delivery
requirements of this arrangement. Contracted volumes relating to this
arrangement are included in the Company's supplemental oil and gas disclosures.
 
     This payment has been classified as an advance on the balance sheet and is
being reduced as gas is delivered to the purchaser under the terms of the
contract. At December 31, 1996 and 1995, $51.8 million and $60.3 million,
respectively, were still outstanding. Gas volumes delivered to the purchaser are
reported as revenue at prices used to calculate the amount advanced, before
imputed interest, minus or plus amounts paid or received by Apache applicable to
the price swap agreement. Interest expense is recorded based on a rate of 9 1/2
percent.

     Public Equity Offering -- In September 1995, Apache completed a public
offering of approximately 7.5 million shares of Apache common stock for net
proceeds of $195.5 million.
 
     Stock Option Plans -- At December 31, 1996, officers and certain key
employees have been granted options to purchase the Company's common stock under
employee stock option plans adopted in 1990 and 1995 and under certain
predecessor plans (collectively, the Stock Option Plans). Under the Stock Option
Plans, the exercise price of each option equals the market price of Apache's
common stock on the date of grant. Options generally become exercisable ratably
over a four-year period and expire after ten years. The Company may issue up to
4,119,163 shares of common stock under the Stock Option Plans, of which options
to acquire 1,231,050 shares of common stock remained available for grant at
December 31, 1996.
 
     On October 31, 1996, the Company established the 1996 Performance Stock
Option Plan (the Performance Plan) for substantially all full-time employees,
excluding officers and certain key employees. Under the Performance Plan, the
exercise price of each option equals the market price of Apache common stock on
the date of grant. All options become exercisable after nine and one-half years
and expire ten years from the date of grant; however, exercisability will be
accelerated if share price goals of $50 and $60 per share, respectively, are
attained before January 1, 2000. The Company may issue up to 1,300,000 shares of
common stock under the Performance Plan, of which options to acquire 272,190
shares of common stock remained available for grant at December 31, 1996.
 
     A summary of the status of the plans described above as of December 31,
1996, 1995, and 1994 and changes during the years then ended is presented in the

     The Company accounts for its stock-based compensation plans under APB
Opinion No. 25 and related Interpretations, under which no compensation cost has
been recognized for the Stock Option Plans or the Performance Plan. If
compensation costs for these plans had been determined in accordance with SFAS
No. 123, the Company's net income and net income per common share would
approximate the following pro forma amounts:

Net Income:

Net Income per Common Share:
  As Reported..........................................  $   1.42    $   .28
  Pro Forma............................................      1.39        .28

 
     The pro forma amounts shown above may not be representative of future
results because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995.
 
     On October 31, 1996, subject to shareholder approval, the Company adopted
the 1996 Share Price Appreciation Plan (the Appreciation Plan) for officers and
certain key employees. The Appreciation Plan provides for awards denominated in
shares of Apache common stock to become payable upon attainment of share price
goals of $50 and $60 per share, respectively, before January 1, 2000. Between 30
and 50 percent of the award will be paid in cash at the market value of the
stock on the date of payment, and the balance (up to a total of 2,000,000 shares
in the aggregate) will be issued in Apache common stock. Generally, any payments
will be made in three installments over 36 months. When and if payments are
made, the Company will recognize compensation expense over the 36 month vesting
period equal to the value of the stock issued on the date the share price goal
is attained (i.e., $50 or $60 per share, as appropriate) and the actual amount
of cash paid. No compensation expense related to the Appreciation Plan has been
included in the pro forma amounts shown above. Additionally, the shares of
Apache common stock contingently issuable under the Appreciation Plan will be
excluded from the computation of net income per common share until the stated
share price goals of $50 and $60 per share, respectively, are attained.
 
     Preferred Stock -- The Company has five million shares of no par preferred
stock authorized, of which 25,000 shares have been "designated" Series A Junior
Participating Preferred Stock and authorized for issuance pursuant to certain
rights that trade with Apache common stock. There are no shares of preferred
stock issued and outstanding; however, shares of preferred stock are reserved
for issuance upon the exercise of the preferred stock purchase rights discussed
below.

     Rights to Purchase Preferred Stock -- In December 1995, the Company
declared a dividend of one right (a Right) for each outstanding share of Apache
common stock effective on January 31, 1996. Each Right entitles the registered
holder to purchase from the Company one ten-thousandth (1/10,000) of a share of
Series A Junior Participating Preferred Stock at a price of $100 per one
ten-thousandth of a share, subject to adjustment. The Rights are exercisable 10
calendar days following a public announcement that certain persons or groups
acquired 20 percent or more of the outstanding shares of Apache common stock or
10 business days following commencement of an offer for 30 percent or more of
the outstanding shares of Apache common stock. Unless and until the Rights
become exercisable, they will be transferred with and only with the shares of
Apache common stock. If the Company engages in certain business combinations or
a 20 percent shareholder engages in certain transactions with the Company, the
Rights become exercisable for Apache common stock or common stock of the
corporation acquiring the Company (as the case may be) at 50 of the then-market
price. Any Rights that are or were beneficially owned by a person who has
acquired 20 percent or more of the outstanding shares of Apache common stock and
who engages in certain transactions or realizes the benefits of certain
transactions with the Company will become void. The Company may redeem the
Rights at $.01 per Right at any time until 10 business days after public
announcement that a person has acquired 20 percent or more of the outstanding
shares of Apache common stock. The Rights will expire on January 31, 2006,
unless earlier redeemed by the Company. Unless the Rights have been previously
redeemed, all shares of Apache common stock issued by the Company will include
Rights.

(1) Includes $10.7 million and $(7.9) million at December 31, 1996 and 1995,
    respectively, for fixed-to-floating price swaps where there is an offsetting
    position with a physical contract. See Commodity Price Hedges below.
 
     The following methods and assumptions were used to estimate the fair value
of the financial instruments summarized in the table above. The carrying values
of trade receivables and trade payables included in the accompanying
Consolidated Balance Sheet approximated market value at December 31, 1996 and
1995.
 
     Cash and Cash Equivalents -- The carrying amounts approximated fair value
due to the short maturity of these instruments.
 
     Investment Securities -- The fair value of investments is based on quoted
market prices at year end.
 
     Long-Term Debt -- The fair values of the 9.25 percent, 9.875 percent and
7.95 percent notes and the 7.625 percent debentures are based on the quoted
market prices for those issues. The fair values of the 3.93 percent convertible
notes and the 7.7 percent notes are estimated based on quotes obtained from
private investment firms. The fair value of the six percent convertible
subordinated debentures is based upon estimates provided to the Company by
independent sources. The carrying amount of the bank debt approximates fair
value because the interest rates are variable and reflective of market rates.
 
     Interest Rate Instruments -- The Company periodically enters into various
financial instruments to manage its interest rate exposure. At December 31,
1996, the Company did not have any outstanding interest rate swap agreements.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Foreign Currency Rate Contracts -- The Company periodically enters into
forward foreign currency exchange contracts to reduce the impact of foreign
currency fluctuations on operating results. At December 31, 1996, Apache did not
have any open forward foreign currency exchange contracts.
 
     Commodity Price Hedges -- Apache periodically enters into commodity
derivative contracts and fixed-price physical contracts to manage its exposure
to oil and gas price volatility. Commodity derivatives contracts, which are
usually placed with major financial institutions that the Company believes are
minimal credit risks, may take the form of futures contracts, swaps or options.
The derivative contracts call for Apache to receive, or make, payments based
upon the differential between a fixed and a variable commodity price as
specified in the contract. As a result of these activities, Apache recognized
hedging losses in 1996 and 1995 of $23.0 and $4.3 million, respectively, while
recognizing a gain of $5.7 million in 1994. The 1995 loss reflected a $9.3
million pre-tax charge to earnings resulting from the loss of correlation of New
York Mercantile Exchange (NYMEX) prices from actual wellhead prices for certain
positions in January through March 1996 production, reported as a reduction of
other revenues, offset by $5 million of commodity pricing gains which increased
1995 oil and gas production revenues. The 1996 hedging loss and the 1994 hedging
gain were recognized in oil and gas production revenues during each of the
respective years.
 
     Apache's consolidated balance sheet includes deferred credits totaling $3.2
million and $4.8 million at December 31, 1996 and 1995, respectively, for gains
realized on the early termination of commodity derivative contracts in 1996 and
prior years. These gains will be recognized as oil and gas production revenues
over periods ranging from one to 48 months as the hedged production occurs.
 
     The following table and notes thereto cover the Company's pricing and
notional volumes on open natural gas commodity derivative contracts as of
December 31, 1996:

(1) The Company has various contracts to supply gas at fixed prices. In order to
    lock in a margin on a portion of the volumes, the Company is a fixed price
    payor on swap transactions. The average physical contract price ranges from
    $2.34 in 1997 to $2.78 in 2000. The fair value of these hedges was $10.7
    million at December 31, 1996, with $1.7 million of this value relating to
    the arrangement discussed in Note 6.
 
     The Company had, as of December 31, 1996, entered into price swaps on oil
production under which the Company will receive a NYMEX fixed price, averaging
$21.09 per barrel, on 800 barrels of daily crude oil production over a
twelve-month period ending December 31, 1997. The fair value of oil hedges was a
$.4 million loss at December 31, 1996.
 
     In connection with the purchase of MW Petroleum Corporation in mid-1991,
the Company and Amoco Production Company (Amoco) entered into a hedging
agreement. Under the terms of this agreement, Amoco receives payments in the
event oil prices rise above specified reference prices for any year during the
eight-year period ending June 30, 1999, or in the event gas prices exceeded
specified reference prices for any year during the five-year period ending June
30, 1996. In the event price sharing payments are due to Amoco, the volumes
listed below would be doubled until Amoco recovers its net payments previously
made to Apache ($5.8 million through the contract year ended June 30, 1996) plus
interest.

     Apache was not required to make any price sharing payments in 1996, and
does not expect to be liable to Amoco for future price sharing payments.
 
10. COMMITMENTS AND CONTINGENCIES
 
     Litigation -- The Company is involved in litigation and is subject to
governmental and regulatory controls arising in the ordinary course of business.
It is the opinion of the Company's management that all claims and litigation
involving the Company are not likely to have a material adverse effect on its
financial position or results of operations.
 
     Environmental -- Apache, as an owner and operator of oil and gas
properties, is subject to various federal, state, local and foreign country laws
and regulations relating to discharge of materials into, and protection of, the
environment. These laws and regulations may, among other things, impose
liability on the lessee under an oil and gas lease for the cost of pollution
clean-up resulting from operations, subject the lessee to liability for
pollution damages and impose restrictions on the injection of liquids into
subsurface strata. Apache maintains insurance coverage which it believes is
customary in the industry, although it is not fully insured against all
environmental risks.
 
     As part of the Company's due diligence review for acquisitions, Apache
conducts an extensive environmental evaluation of purchased properties.
Depending on the extent of an identified environmental problem, the Company may
exclude a property from the acquisition, or agree to assume liability for
remediation of the property. As of December 31, 1996, Apache had a reserve for
environmental remediation of approximately $6.6 million. The Company is not
aware of any environmental claims existing as of December 31, 1996, which have
not been provided for or would otherwise have a material impact on its financial
position or results of operations. There can be no assurance, however, that
current regulatory requirements will not change, or past non-compliance with
environmental laws will not be discovered on the Company's properties.
 
     International Commitments -- The Company, through its subsidiaries, has
acquired or has been conditionally or unconditionally granted exploration rights
in Australia, Egypt, The People's Republic of China, Indonesia and the Ivory
Coast. In order to comply with the contracts and agreements granting these
rights, the Company, through various wholly owned subsidiaries, is committed to
expend approximately $306.0 million through 2000.
 
     Retirement and Deferred Compensation Plans -- The Company provides a
retirement/401(k) savings plan and a non-qualified retirement/savings plan for
employees. These plans allow participating employees to elect to contribute up
to 10 percent of their salaries, with Apache making matching contributions up to
a maximum of six percent of each employee's salary. In addition, the Company
annually contributes a percentage of each participating employee's compensation,
as defined, to the plan. Vesting in the Company's contributions occurs at the
rate of 20 percent per year. Additionally, DEKALB maintains a separate
retirement plan. Total expenses under all plans were $6.3 million, $7 million
and $5.8 million for 1996, 1995 and 1994, respectively. The unfunded liability
for all plans has been accrued in the consolidated balance sheet.

     Lease Commitments -- The Company has leases for office space and equipment
with varying expiration dates through 2007. Net rental expense was $6.5 million,
$5.2 million and $4.4 million for 1996, 1995 and 1994, respectively.
 
     ProEnergy -- ProEnergy's limited liability company agreement provides that
capital funding obligations, allocations of profit and loss and voting rights
are calculated based upon the members' respective throughputs of natural gas
sold to ProEnergy. Each member's liability with respect to future capital
funding obligations is subject to certain limitations. Natural gas throughputs
are calculated, profit distributed, and/or capital called on a quarterly basis.
As of December 31, 1996, the Company held an approximate 44 percent interest in
ProEnergy.
 
     As of December 31, 1996, minimum rental commitments under long-term
operating leases and long-term pipeline transportation commitments, ranging from
15 to 27 years, are as follows:

11. CUSTOMER INFORMATION
 
     Major Purchasers -- ProEnergy purchases accounted for 35 percent of the
Company's oil and gas revenues in 1996. Beginning with April 1996 production,
ProEnergy was the principal purchaser of Apache's domestic natural gas
production.
 
     Natural Gas Clearinghouse (NGC) was the principal purchaser of Apache's
spot market gas production from April 1990 through September 30, 1995. Sales to
NGC accounted for 27 percent and 37 percent of the Company's oil and gas
revenues in 1995 and 1994, respectively.
 
     Concentration of Credit Risk -- The Company's revenues are derived
principally from uncollateralized sales to customers in the oil and gas
industry; therefore, customers may be similarly affected by changes in economic
and other conditions within the industry. Apache has not experienced significant
credit losses on such sales.
 
     Sales of natural gas by Apache to ProEnergy are similarly uncollateralized.
Apache and the other members of ProEnergy have agreed to fund the reasonably
anticipated future capital needs of ProEnergy. In addition, effective January
31, 1996, ProEnergy entered into a $150 million, three-year revolving credit
facility with a syndicate of banks to finance its operations. ProEnergy is,
however, subject to the risks inherent in the natural gas marketing industry.

     Oil and Gas Reserve Information -- Proved oil and gas reserve quantities
are based on estimates prepared by the Company's engineers in accordance with
guidelines established by the Securities and Exchange Commission (SEC). The
Company's estimates of proved reserve quantities of its U.S., Canadian and
certain international properties are subject to review by Ryder Scott Company
Petroleum Engineers, independent petroleum engineers, while the proved reserve
quantities of the Company's Egyptian properties are reviewed by Netherland,
Sewell & Associates, Inc., independent petroleum engineers.
 
     There are numerous uncertainties inherent in estimating quantities of
proved reserves and projecting future rates of production and timing of
development expenditures. The following reserve data represents estimates only
and should not be construed as being exact.

     Future Net Cash Flows -- Future cash inflows are based on year-end prices
except in those instances where the sale of natural gas or oil is covered by
physical or derivative contract terms providing for higher or lower amounts.
Operating costs, production and ad valorem taxes and future development costs
are based on current costs with no escalation.
 
     The following table sets forth unaudited information concerning future net
cash flows for oil and gas reserves, net of income tax expense. Income tax
expense has been computed using expected future tax rates and giving effect to
tax deductions and credits available, under current laws, and which relate to
oil and gas producing activities. This information does not purport to present
the fair market value of the Company's oil and gas assets, but does present a
standardized disclosure concerning possible future net cash flows that would
result under the assumptions used.

    $25.7 million ($5.3 million, $9.8 million and $9.8 million after discount at
    10 percent per annum) for 1996, 1995 and 1994, respectively, of Canadian
    provincial tax credits expected to be realized beyond the date at which the
    legislation, under its provisions, could be repealed.
 
(2) Estimated future net cash flows before income tax expense, discounted at 10
    percent per annum, totaled approximately $4.6 billion, $2.3 billion and $1.6
    billion as of December 31, 1996, 1995 and 1994, respectively.

     Impact of Pricing -- The estimates of cash flows and reserve quantities
shown above are based on year-end oil and gas prices, except in those cases
where future gas sales are covered by contracts at specified prices. Estimates
of future liabilities and receivables applicable to oil and gas commodity hedges
are reflected in future cash flows from proved reserves with such estimates
based on prices in effect as of the date of the reserve report. Fluctuations are
largely due to supply and demand perceptions for natural gas and volatility in
oil prices.
 
     Under SEC rules, companies that follow full cost accounting methods are
required to make quarterly "ceiling test" calculations. Under this test,
capitalized costs of oil and gas properties may not exceed the present value of
estimated future net revenues from proved reserves, discounted at 10 percent,
plus the lower of cost or fair market value of unproved properties, as adjusted
for related tax effects and deferred income taxes. Application of these rules
generally requires future production to be priced at the unescalated oil and gas
prices in effect at the end of each fiscal quarter and requires a writedown if
the "ceiling" is exceeded, even if prices declined for only a short period of
time.
 
     Many full cost companies, including Apache, are concerned about the impact
of prolonged unfavorable gas prices on their ceiling test calculations. A
deterioration of gas or oil prices from year-end levels could result in the
Company recording a non-cash charge to earnings related to its oil and gas
properties. The SEC may permit the exclusion of capitalized costs and present
value of recently acquired properties in performing ceiling test calculations.
Pursuant thereto, Apache, in 1995, requested waivers and the SEC granted two
separate one-year waivers with respect to the properties acquired from Texaco
and Aquila. Such waivers expired in 1996.
