                 Anadarko Announces Strong Third Quarter Results

    HOUSTON--(BUSINESS WIRE)--Oct. 28, 2005--Anadarko Petroleum Corporation
(NYSE:APC) today announced third quarter 2005 net income available to
common shareholders of $596 million, or $2.51 per share (diluted), on
revenues of $1.76 billion.
    Quarterly results include $141 million ($90 million after-tax) of
unrealized losses on derivatives, partially offset by a $29 million
($19 million after-tax) unrealized gain related to the company's firm
transportation keep-whole agreement. The quarter also included a $13
million (after-tax) charge related to the disposition of Block 30 in
Oman, which was part of the restructuring plan announced in June 2004.
    Cash flow from operating activities was $1.14 billion in the third
quarter, and discretionary cash flow totaled $1.01 billion.(1)
    "Anadarko's results were strong, even with the impact of several
non-cash items and unusual events, not the least of which were two
100-year storms in one quarter," said Anadarko President and CEO Jim
Hackett. "Revenues were up year-over-year and, importantly, we reduced
direct operating costs 26 percent for the same period. As a result, we
were able to expand our cash margins, partly because of higher
commodity prices, but also due to our restructured, more efficient
asset base."
    Between the end of the second quarter and Oct. 12, Anadarko
purchased 5.5 million shares to complete the company's stock
repurchase program, which began in June 2004. A total of 28.4 million
shares were purchased under the $2 billion program, at an average cost
of $70.50 per share (including all trading expenses).
    Third quarter sales volumes totaled 39 million barrels of oil
equivalent (BOE), or 426,000 BOE per day. Natural gas sales volumes
averaged 1,382 million cubic feet per day, at an average realized
price of $7.15 per thousand cubic feet. Oil sales volumes in the third
quarter averaged 162,000 barrels per day, with an average realized
price of $50.80 per barrel. Natural gas liquids volumes averaged
34,000 barrels per day, at an average realized price of $37.61 per
barrel.
    Overall volumes were essentially flat from the second quarter
2005, despite the temporary impact of hurricanes, and were down
year-over-year due to property sales associated with Anadarko's
refocused strategy. Adjusted for these property sales, volumes
increased 8 percent year to date 2005 compared to the prior year.
    Offshore Gulf of Mexico, Anadarko's gross volumes of approximately
20,000 BOE per day were shut in for a combined 20 days during the
third quarter because of Hurricanes Katrina and Rita. In total, the
company estimates that combined onshore and offshore weather-related
shut-ins and delays, including those affecting rigs being used to
develop the K2, K2 North and Genghis Khan fields, reduced third
quarter net volumes by 400,000 BOE.
    As announced earlier, full-year 2005 net volumes are expected to
be reduced by approximately 2.2 million BOE due to the shut-ins and
ongoing effects of the delayed development activity, including delays
due to offshore loop currents.
    "Anadarko continues to make solid progress on its growth strategy
with new initiatives underway internationally and in the Gulf of
Mexico, where we acted quickly to lock up several new resource
opportunities, as well as a separate decision to secure additional
offshore drilling rigs to carry out our active program over the coming
years," Hackett added. "Our exploration mindset is a differentiating
feature of Anadarko, as we invest over 25% of our capital to carry out
our mission to add new hydrocarbon reserves to meet the world's
increasing needs, as well as provide competitive and sustainable
growth for our shareholders."

    THIRD QUARTER 2004

    Third quarter 2004 net income available to common shareholders was
$399 million, or $1.58 per share (diluted), on revenues of $1.56
billion. Cash flow from operating activities for the same period was
$992 million, while discretionary cash flow totaled $617 million.(1)

                    Anadarko Petroleum Corporation
             Reconciliation of GAAP to Non-GAAP Measures

Below is a reconciliation of cash provided by operating activities
(GAAP) to discretionary cash flow (non-GAAP) as required under
Regulation G of the Securities Exchange Act of 1934. The company uses
discretionary cash flow 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.
