BR AND TALISMAN ANNOUNCE SUCCESSFUL APPRAISAL WELL IN ALGERIA.

HOUSTON--(BUSINESS WIRE)--May 6, 1999--

Burlington Resources Inc. (NYSE:BR) through its wholly-owned subsidiary, LL&E Algeria Ltd.; Sonatrach, the National Oil and Gas Enterprise of Algeria; and Talisman Energy Inc. of Canada through its wholly-owned subsidiary, Talisman (Algeria) B.V.; today announced successful test results from the MLN-6, an appraisal well on the Menzel Lejmat Block 405 in the Berkine Basin of Algeria. Two intervals in the TAG-I Formation were tested and flowed at 3,553 barrels of 44 degree API gravity oil and 4.98 million cubic feet of natural gas per day on a one-inch choke with 492 psi flowing wellhead pressure.

LL&E Algeria Ltd. operates the MLN-6 well, located approximately 2.5 kilometers (1.6 miles) south southwest of the MLN-3 well. The MLN-6 well is the thirteenth successful well drilled on Block 405 and is the last appraisal well to be drilled in the MLN field prior to "first phase" development.

Bobby S. Shackouls, BR's chairman, president and chief executive officer commented, "With the successful drilling of the MLN-6 well, we have further appraised one of the MLN area accumulations. We are now finalizing our exploitation license application for the development of the Triassic interval in the adjacent MLN-1, 2, 4 and 5 area, which is fully appraised. This step will move us closer to first production from Block 405 in the very prolific Berkine Basin of Algeria."

Burlington Resources, through its wholly-owned subsidiary, LL&E Algeria Ltd., has a 65 percent working interest in this productive area under a Production Sharing Contract with Sonatrach. Talisman Energy Inc. through its wholly-owned subsidiary, Talisman (Algeria) B.V. holds the remaining 35 percent working interest. Sonatrach has an option to participate in the development and production of commercial discoveries. Burlington Resources and Talisman are entitled to recover exploration costs out of production during the exploitation phase.
