          Anadarko Announces Strong First-Quarter Earnings,
            Increases Capital Budget, Raises 2003 Guidance


    HOUSTON--(BUSINESS WIRE)--April 25, 2003--Anadarko Petroleum
Corporation (NYSE:APC)

    --  Earnings driven by higher energy prices

    --  Capital budget increased by 9 percent to $2.5 billion

    --  Exploration success logged in Gulf of Mexico, Canada and
        Algeria

    --  Production volumes set to grow throughout 2003

    Anadarko Petroleum Corporation (NYSE:APC) today announced net
income available to common shareholders of $418 million, or $1.63 per
share (diluted), on revenues of $1.26 billion for the first quarter of
2003. Results include an after-tax gain of $47 million, or 18 cents
per share (diluted) related to the Jan. 1, 2003 adoption of Statement
of Financial Accounting Standards No. 143, "Accounting for Asset
Retirement Obligations." Net income available to common shareholders
before the cumulative effect of the change in accounting principle was
$371 million, or $1.45 per share (diluted). For the same period in
2002, the company earned $88 million, or 34 cents per share (diluted),
on revenues of $790 million.
    The increase in earnings in the first quarter of 2003 is primarily
due to sharply higher commodity prices, partly offset by lower sales
volumes resulting from the divestiture of some low-margin North
American producing properties in 2002 and other temporary factors
affecting production from international fields.
    "We had a great start to what we expect to be a year of record
earnings for the company," said Robert J. Allison, Jr., Anadarko
Chairman, President and CEO. "Our first quarter performance was
stronger than we had forecast, both operationally and financially.
    "We had some nice discoveries in the Gulf of Mexico, Canada and
Algeria, and we still have a number of high-impact exploration wells
drilling that will be completed early in the second quarter.
    "Strong energy prices in the first quarter allowed us to fund an
aggressive exploration and development drilling program and still have
excess cash flow, which enabled us to further strengthen our balance
sheet," Allison said.
    During the first quarter of 2003, sales volumes totaled 45 million
barrels of oil equivalent (BOE), or 498,000 BOE per day, down 10
percent from the first quarter of 2002 due to several factors,
including:


    1) the divestiture in 2002 of approximately 7 million BOE of
        annual production in North America, primarily heavy oil in
        Canada;

    2) the scheduled shut-in of the Al Rayyan oil field in Qatar since
        February to install a new production facility;

    3) the effect of higher oil prices in Venezuela - where contract
        terms with the national oil company provide Anadarko with
        specific amounts of revenues that are converted to volume
        equivalents at prevailing market prices, giving Anadarko lower
        oil volumes when prices increase; and

    4) the completion of cost recovery in Algeria. Anadarko previously
        had been reimbursed for earlier exploration spending with
        additional barrels of oil production.



    North American natural gas volumes of 1.7 billion cubic feet (Bcf)
per day were 6 percent lower than a year earlier due to a 10 percent
decline in U.S. production, partly offset by a 12 percent increase in
production from Western Canada. Anadarko's realized average natural
gas price in the first quarter of 2003 was $4.62 per thousand cubic
feet (Mcf) - more than double that of the year-earlier period.
    Oil production in the first quarter was 173,000 barrels a day - 18
percent lower than a year earlier - as a result of the factors
mentioned above. Realized oil prices, meanwhile, were 54 percent
higher than a year ago, at $28.59 per barrel.
    "We expect production volumes to build each quarter throughout the
year, as we bring on additional production in the Gulf of Mexico,
Canada, Qatar and the Lower 48," Allison said. "Total volumes in the
fourth quarter of this year should be about 20 percent higher than in
the first quarter," he noted.
    "We're still expecting 2003 volumes to be about 5 percent higher
than last year's volumes, adjusting for the effect of our 2002
property sales. Next year's volumes are forecast to increase 12
percent over 2003 levels," Allison said.

    FIRST QUARTER 2003 OPERATING HIGHLIGHTS

    --  In the Gulf of Mexico, Anadarko made a natural gas discovery
        at its Jubilee prospect, the first well in Anadarko's Eastern
        Gulf exploration program. The Atwater Valley 349 No. 1 well
        was drilled in 8,800 feet of water to a target depth of 18,310
        feet and encountered 83 feet of net pay. Although the company
        has not yet determined proved reserves, the estimated recovery
        is expected to be 40 million to 50 million BOE. The company
        believes Jubilee could be commercially produced when hub
        facilities are established in the area.


        Anadarko also authorized construction of an $86 million
        production platform for its Tarantula subsalt discovery on
        South Timbalier Block 308. The platform will have a capacity
        of 100 million cubic feet (MMcf) per day of natural gas and
        30,000 barrels per day of oil. First production is expected in
        the fourth quarter of 2004.

        Anadarko holds a 100 percent working interest in both fields.



    --  In North Louisiana, average daily gross natural gas production
        from the Vernon area increased from the fourth quarter of 2002
        by 26 percent to 120 MMcf per day in the first quarter of
        2003. First-quarter drilling focused on extending the Vernon
        field boundaries and developing the "sweet spots." Among the
        standout wells drilled during the quarter was the Smith 9-1 in
        the northwest portion of the field, which tested at 11.5 MMcf
        of gas per day. Anadarko has a 97.7 percent working interest
        in that well. Four others also tested at rates between 8 MMcf
        and 10 MMcf per day. Several offsets are planned.

    --  In Algeria, Anadarko and partners Sonatrach, Maersk and
        Eni-Lasmo announced the partnership's second oil discovery
        since resuming exploration in October 2002 on Block 404 in the
        Berkine Basin. The SFSW-1 discovery well was drilled to a
        total depth of 10,637 feet and encountered 36 feet of net oil
        pay in the TAGI reservoir. It tested at a rate of 2,689
        barrels per day of 47 degree API gravity oil and 4.72 MMcf per
        day of gas.

    --  In Canada, Anadarko announced a natural gas discovery in the
        Saddle Hills area of Alberta, increasing proved reserves by
        over 40 Bcf of gas from this multi-zone play. The Saddle Hills
        15-34-75-7W6 discovery well, drilled into the Devonian, flowed
        at a rate of 15.9 MMcf per day of gas. With this 100
        percent-owned well online and other activity this year, total
        gas production from Saddle Hills increased to 80 MMcf per day,
        compared with just 2 MMcf per day a year earlier.

    FINANCIAL DATA

    Three pages of summary financial data for the first quarter of
2003 follow, as well as one page providing detailed financial guidance
for the second quarter and full year 2003. In addition, another page
summarizes the company's current hedge positions for the second
quarter of 2003 and for the remainder of 2003 and 2004.

    CAPITAL BUDGET INCREASE

    The Board of Directors has approved a $200 million increase in the
company's 2003 capital budget, which will enable Anadarko to
accelerate its exploration program in the Gulf of Mexico, Algeria and
Canada and more aggressively develop key producing fields in Canada
and East Texas. This increase, about three-quarters of which will go
toward exploration, will raise Anadarko's capital budget to $2.5
billion.

    EARNINGS GUIDANCE

    Anadarko expects to earn $289 million, or $1.15 per share
(diluted) for the second quarter of 2003, with expected cash flow from
operating activities of $710 million. The expected average number of
diluted shares outstanding is 252 million.
    For the full year, the company expects earnings of $1.39 billion,
or $5.51 per share (diluted) and cash flow from operating activities
of $3.16 billion. The expected average number of diluted shares
outstanding is 253 million.
    Second-quarter and full year 2003 estimates of shares outstanding
reflect the redemption on April 15, 2003, of the company's Zero Coupon
Convertible Debentures due 2020. Anadarko paid $556.46 per debenture,
reflecting the issue price plus accrued interest as of the redemption
date, which is equivalent to $47.85 per share under the conversion
provisions.

    Price Assumptions

    Anadarko's 2003 estimates assume average NYMEX oil prices of $27
per barrel for the second quarter, dropping to $25 per barrel for the
remainder of the year, with a full-year average of $27.75 per barrel.
The company's NYMEX natural gas price estimate is $5 per Mcf both for
the second quarter and the remainder of the year, with a full-year
average of $5.40 per Mcf.
    To determine realized prices, Anadarko used these estimates, plus
or minus an expected price "differential" for each of the company's
major producing areas, and any adjustment for hedge positions.
    For 2003, Anadarko has hedged approximately 51 percent of its
natural gas production for the second quarter and 45 percent for July
through December. About 32 percent of Anadarko's oil production is
hedged through December 2003. The hedge positions are under both
fixed-price transactions and "collared" transactions, which use price
ceilings and floors to help ensure sales prices within a determined
range.

    Volume Assumptions

    Oil and gas sales volumes are expected to total 48 million BOE in
the second quarter. Full-year 2003 sales volumes are expected to total
200 million BOE.
