             Anadarko Announces Strong First Quarter 2004 Earnings

     HOUSTON--(BUSINESS WIRE)--April 30, 2004--Anadarko Petroleum Corporation
(NYSE:APC) today announced first quarter 2004 net income available to common
shareholders of $392 million, or $1.55 per share (diluted), on revenues of $1.46
billion. Net income included a $40 million after-tax charge for an operating
lease settlement related to a former UPR-owned refinery in Corpus Christi,
Texas. Net income excluding this charge was $1.70 per share (diluted).(1) For
the same period in 2003, net income before the cumulative effect of a change in
accounting principle was $371 million, or $1.45 per share (diluted), on revenues
of $1.26 billion. Including the accounting change, net income was $418 million,
or $1.63 per share (diluted), in the 2003 first quarter.
     "Strong volumes and favorable variances on expenses compared to our
guidance, in addition to robust commodity prices, have us on track to deliver on
the performance metrics we've laid out for shareholders this year," said
Anadarko President and CEO Jim Hackett. "The resulting income and cash flows are
providing the ability to fund our active capital program, improve returns,
strengthen our balance sheet and achieve year-over-year growth."
     Cash flow from operating activities totaled $885 million in the first
quarter 2004, compared to $705 million for the first quarter 2003. Cash flow
from operations before changes in assets and liabilities for the first quarter
2004 totaled $944 million, compared to $794 million for the first quarter
2003.(1)
     During the first quarter of 2004, sales volumes totaled 49 million barrels
of oil equivalent (BOE), or 538,000 BOE per day, up 8 percent from 2003 first
quarter sales volumes of 498,000 BOE per day.
     Oil sales volumes in the first quarter were 202,000 barrels per day (bpd),
compared to 173,000 bpd in the same quarter of 2003. The 17 percent increase is
mainly attributed to the company's Algerian operations, due to the timing of
cargo liftings and the expansion of production facilities and infrastructure.
The company's average realized oil prices were $29.94 per barrel, compared with
2003 first quarter prices of $28.64 per barrel.
     North American natural gas sales volumes of 1,723 million cubic feet (MMcf)
per day rose 1 percent from first quarter 2003 volumes of 1,705 MMcf per day.
Anadarko's average realized natural gas price in the first quarter of 2004 was
$4.92 per thousand cubic feet (Mcf), compared with $4.60 per Mcf for the same
period in 2003.

              Reconciliation of GAAP to Non-GAAP Measures

Below is a reconciliation of net income before cumulative effect of
change in accounting principle (GAAP) to net income before cumulative
effect of change in accounting principle and operating lease
settlement charge (non-GAAP) related to a former UPR-owned refinery in
Corpus Christi, Texas, as required under Regulation G of the
Securities Exchange Act of 1934. The company uses net income before
change in accounting principle excluding the operating lease
settlement charge, included in other (income) expense, to evaluate the
company's results from current operations. The operating lease
settlement charge net of income taxes is excluded due to the lack of
comparability between periods.

Below is a reconciliation of cash provided by operating activities
(GAAP) to cash flow from operations before changes in assets and
liabilities (non-GAAP) as required under Regulation G of the
Securities Exchange Act of 1934. The company uses cash flow from
operations before changes in assets and liabilities to demonstrate the
company's ability to internally fund capital expenditures and to
service or incur additional debt. It is useful in comparisons of oil
and gas exploration and production companies because it excludes
fluctuations in assets and liabilities.
