                    Anadarko Announces 2005 Budget

    HOUSTON--(BUSINESS WIRE)--Nov. 19, 2004--Anadarko Petroleum
Corporation (NYSE:APC)

    --  ANTICIPATE 7-11% VOLUME GROWTH IN 2005

    --  CAPITAL EXPENDITURES OF $2.9 BILLION - $3.1 BILLION

    --  INCREASE IN EXPLORATION SPENDING TO SUSTAIN GROWTH

    Anadarko Petroleum Corporation (NYSE:APC) announced today that its
Board of Directors has approved a 2005 budget in the range of $2.9
billion to $3.1 billion.
    The program is expected to deliver 7 to 11 percent production
volume growth in 2005, or 160 million to 165 million barrels of oil
equivalent (BOE), over 2004 pro forma(a) performance of 148 million to
151 million BOE. It also includes increased spending on exploration to
sustain volume growth beyond the next five years.
    "Anadarko expects to achieve sustainable, profitable growth by
leveraging our skill sets on the things we do well - developing
unconventional resources and exploring in high-potential basins -
while regularly high-grading our portfolio and maintaining financial
discipline," said Jim Hackett, Anadarko President and CEO.
    Anadarko has implemented a refocused strategy, presented in June,
by balancing the portfolio through announced asset sales totaling $3.3
billion, repurchasing 12.9 million outstanding shares at a cost of
$819 million and retiring about $1.2 billion of debt.
    "Our 2005 capital budget is essentially unchanged from 2004
capital expenditures, despite the asset divestitures," Hackett said.
"That's largely because we decided to exercise the strategic option to
accelerate drilling certain PUDs - or proven undeveloped locations -
primarily on our low-risk North American unconventional gas
properties. This $200 million program is designed to capitalize on
today's high commodity price environment, adding about $150 million of
net asset value with a payback period of just over two years, while
increasing our 2005 production volume growth by about 2.5 million BOE.
In addition, while we intend to drive down costs where possible, we
have budgeted $400 million for potential increases in oil field
services and materials."
    Approximately 64 percent of the total budget is planned for
development activities, 25 percent will go to exploration and the
remaining 11 percent is set aside for capitalized interest, overhead
and other items.
    Development spending to generate volume growth in 2005 will focus
on Anadarko's continued success in unconventional tight gas plays in
the Vernon field in North Louisiana and Wild River in Alberta, Canada,
and on delineating new plays in Texas and Louisiana. Production will
continue to ramp up at the company's enhanced oil recovery operations
at the Salt Creek and Monell fields in Wyoming. In the Gulf of Mexico
(GOM), Anadarko will focus on delineation drilling and facilities
installation in the deepwater at K2, K2 North and the Eastern GOM,
which are expected to be significant contributors to the company's
volume growth through 2008. In Alaska, we're expanding the Alpine
facility to increase capacity.
    Venezuela is expected to generate good volume growth in 2005. In
Algeria, the company expects to make significant progress on the
development of Block 208 discoveries, with the new production
facilities scheduled to come on-line in 2007.
    "As always, exploration is a cornerstone of Anadarko's strategy
and we intend to carry that commitment forward in 2005 by allocating a
quarter of our capital budget to find new sources of energy for the
world's needs," Hackett said.
    The exploration budget will focus on a number of key areas in the
deepwater GOM, including prospects such as Genghis Khan, Knotty Head
and Mondo Northwest in the Eastern GOM. In addition, the company will
explore for deep gas objectives in the onshore U.S. and Canada.
    International exploration will focus on drilling programs in
Algeria, Qatar, Tunisia and Indonesia, as well as activities within
our targeted new venture areas.


2005 CAPITAL BUDGET BY TYPE             2005 CAPITAL BUDGET BY AREA
Tight Gas               34%             U.S. Onshore             46%
Deepwater GOM           23%             Deepwater GOM            23%
Enhanced Oil Recovery    6%             Canada                   13%
Conventional E&P        12%             International             9%
Fractured Reservoirs     5%             Corporate                 9%
Coalbed Methane          2%
International            9%
Corporate                9%


    The company's capital program is expected to more than replace
annual production for the 24th consecutive year and increase proved
reserves by 4 percent to 7 percent in 2005. Finding and development
(F&D) costs for 2005 are expected to be between $9 and $12 per BOE.
    "With commodity prices substantially above mid-cycle levels, we
expect F&D costs to be higher. But more importantly, our cash margins
have risen more than F&D costs, so returns have improved
significantly. We expect a reserve replacement of 150 percent to 200
percent and a reserve replacement efficiency of 1.8 to 2.2," Hackett
said. "So, in this price environment it makes perfect sense to
accelerate development projects to get volumes on-line sooner, even if
these strategic decisions drive up a single-point metric such as F&D."
