           APACHE REPORTS RECORD SECOND-QUARTER OIL AND GAS PRODUCTION

         Houston, July 24, 2003 - Apache Corporation (NYSE: APA) today reported
that record production fueled second-quarter earnings of $243 million, or $1.49
per diluted common share, including the impact of a non-cash charge related to
foreign currency fluctuations. Apache reported net income of $143 million, or 95
cents per share, in the prior-year period.

         Excluding the non-cash charge, Apache earned $288 million or $1.76 per
diluted common share. (See below for reconciliation of this non-GAAP number.)
The $45 million charge (27 cents per share) was the result of recognizing
unrealized foreign currency gains and losses caused by the weakening U.S.
dollar.

         Approximately one half of the non-cash charge was the result of a
theoretical tax on a theoretical gain calculated as though Apache had prepaid
the U.S. dollar-denominated long-term debt of its Canadian subsidiaries in
stronger Canadian dollars. As the company did not prepay the debt, nor realize a
gain, nor incur a tax, Apache believes it should not record the charge. Although
Apache recorded the charge in the second quarter, the company will seek to
resolve this issue with the Securities and Exchange Commission and the Financial
Accounting Standards Board.

APACHE REPORTS RECORD PRODUCTION - ADD ONE

         Oil production rose nearly 40 percent to 211,701 barrels per day in the
second quarter, compared with 151,480 barrels per day in the year-earlier
period. Natural gas production averaged 1.25 billion cubic feet (Bcf) per day,
up 15 percent from 1.1 Bcf per day in the prior-year period. Natural gas liquids
production averaged 9,342 barrels per day, up from 8,483 barrels per day in the
prior-year period.

         Cash from operations increased to $639 million from $388 million in the
prior-year period. (Please see below for a reconciliation of Apache's
calculation of cash from operations, a non-GAAP financial measure.)

         For the six months ended June 30, Apache earned net income of $580
million, or $3.59 per diluted share, including $56 million, or 34 cents per
share, in non-cash charges related to foreign currency fluctuations. Excluding
the non-cash charges, Apache earned $636 million, or $3.93 per share, in the
first half. Apache earned $219 million, or $1.47 per share, in the first half of
2002. First-half cash from operations increased to $1.3 billion from $677
million in the prior-year period.

         "Record production was just part of the story behind Apache's
second-quarter results," said G. Steven Farris, president and chief executive
officer. "We had significant drilling successes and we have completed $1.5
billion in acquisitions year-to-date, the impact of which will be reflected in
future quarters."

         Early in the second quarter, Apache completed its two-part acquisition
of BP assets in the North Sea and the Gulf of Mexico. On July 2, Apache
announced an additional acquisition of fields in the Gulf from Shell Exploration
and Production Company.

         "We also maintained our financial flexibility, with a lower
debt-to-capitalization ratio than at the beginning of the year, even with the
acquisitions," Farris said.

APACHE REPORTS RECORD PRODUCTION - ADD TWO

         Apache recently announced several significant discoveries, three of
which opened new plays:

         o The Qasr-1X tested at a combined rate of 51.8 million cubic feet
(MMcf) of natural gas and 2,688 barrels of condensate per day from two zones and
logged 606 feet of net pay from six formations. "We believe the Qasr-1X, in
Egypt's Khalda Concession, is the most significant Western Desert discovery in
the last decade, as it opens a new play over widespread acreage," Farris said.

         o On the Matruh Concession in Egypt, Apache drilled the Alexandrite-1X
wildcat to 15,300 feet in the Jurassic Lower Safa formation. The well logged 146
net feet of gas and condensate pay; a test of the Kabrit interval flowed at a
daily rate of 20 MMcf and 1,683 barrels of condensate. "These discoveries are
important for Apache and for Egypt because the country shares in the economic
benefit associated with finding oil and gas to meet its energy needs," Farris
said.

         o In early July, Apache's Ravensworth-1 well discovered oil in the
Exmouth Sub-Basin offshore Western Australia. "This discovery is the most
important well we've drilled in Australia this year," Farris said.

         Apache Corporation is an independent oil and gas exploration and
production company with core operations in the United States, Canada, Egypt, the
United Kingdom North Sea and Western Australia.

         This news release contains certain "forward-looking statements" as
defined by the Private Securities Litigation Reform Act of 1995, including,
without limitation, expectations, beliefs, plans and objectives regarding
Apache's capital expenditures and future production. Among the important factors
that could cause actual results to differ materially from those indicated by
such forward-looking statements are delays and difficulties in completing
acquisitions and developing currently owned properties, the failure of
exploratory drilling to result in commercial wells, delays due to the limited
availability of drilling equipment and personnel, fluctuations in oil and gas
prices, general economic conditions and the risk factors detailed from time to
time in Apache's periodic reports and registration statements filed with the
Securities and Exchange Commission.

NOTE: Apache will conduct its quarterly conference call to discuss second
quarter results on Thursday, July 24, at 1 p.m. Central Time. The call will be
webcast live on Apache's Web site, www.apachecorp.com. The conference call will

NON-GAAP FINANCIAL MEASURES:

   Cash from operations represents net cash provided by operating activities
   before changes in operating assets and liabilities. Cash from operations is
   presented because management believes it is a useful adjunct to net cash
   provided by operating activities under accounting principles generally
   accepted in the United States (GAAP). Cash from operations is widely accepted
   as a financial indicator of an oil and gas company's ability to generate cash
   which is used to internally fund exploration and development activities and
   to service debt. Cash from operations is not a measure of financial
   performance under GAAP and should not be considered as an alternative to cash
   flows from operating, investing, or financing activities, as an indicator of
   cash flows, or as a measure of liquidity. The following table reconciles net
   cash provided by operating activities to cash from operations.

Earnings per share before non-cash adjustments, a non-GAAP financial measure,
excludes items (such as the impact of currency fluctuations on deferred taxes)
that management deems not representative of the Company's financial performance.
Management believes this measure provides a clearer understanding of the
Company's financial results and enables investors to better compare its results
with those of other companies.
