Monday March 31, 10:14 am ET

First quarter 2003 per-share earnings estimate raised 20 cents to $1.35 / cash flow per share raised 40 cents to $3(a)

NEW ORLEANS--(BUSINESS WIRE)--March 31, 2003-- Anadarko Petroleum Corporation (NYSE:APC - News) today updated its first quarter 2003 financial guidance, increasing its earnings estimate to $1.35 per share (diluted) from $1.15 per share announced previously and its cash flow estimate to $3 per share from $2.60 per share.

"With the strong oil and gas prices, we're looking for first quarter cash flow and earnings that are more than 15 percent above the guidance levels we issued just two months ago," Anadarko Chairman, President and CEO Robert J. Allison, Jr. said today during the 31st Annual Howard Weil Energy Conference.

Allison reaffirmed Anadarko's forecast of 5 percent production growth for 2003 and 12 percent for 2004. "Our goal is double-digit production growth, which we can achieve -- and also post strong financial returns," Allison stressed. "We will continue to improve our returns and cash margins, and we will continue to work on costs."

Allison said fourth quarter 2003 production volumes should be about 20 percent higher than those of the first quarter of 2003, reflecting a 20 percent increase in development drilling activity planned this year. "The momentum of increasing volumes every quarter is key to the growth we expect in 2004," he noted.

Anadarko has an aggressive exploration program under way for 2003 that already has yielded some excellent results, Allison noted.

Since resuming its Algerian exploration program last October, the company has made two oil discoveries on Block 404 east of the Hassi Berkine field. Four more exploration wells on Block 404 and 208 are planned this year.

In Canada, Anadarko has been very successful in the Saddle Hills play, where the company is continuing to add gas reserves through new discoveries and grow production. Saddle Hills production has grown from 2 million cubic feet a day to 80 million cubic feet a day over the last 18 months. Anadarko also is conducting follow-up exploration this winter in the Fort Liard area of the Southern Territories to commercialize a gas discovery made in 2002.

Anadarko Petroleum Corporation is one of the world's largest independent oil and gas exploration and production companies. Houston-based Anadarko is active in the U.S., Canada, Algeria and Qatar and is executing strategic exploration programs in several other countries. More information is available at www.anadarko.com.

(a) Cash flow per share of $3 is calculated using cash flow from operating activities, before changes in assets and liabilities, or about $775 million divided by 258 million diluted shares outstanding.
