BR AND TALISMAN ANNOUNCE DISCOVERY OF NEW ALGERIAN OIL FIELDS.

HOUSTON--(BUSINESS WIRE)--June 23, 1998--Burlington Resources (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 today announced the successful testing of the MLSE-1 well, a new wildcat discovery well on the Menzel Lejmat Block 405 in the Berkine Basin of Algeria. The well flow tested at a combined rate of 14,638 barrels of hydrocarbon liquids and 107 million cubic feet of natural gas per day from four intervals with a combined net pay of 57 meters (190 feet).

LL&E Algeria Ltd. operates the MLSE-1 well which is located in the southeastern portion of Block 405. The well was drilled to a total depth of 4,407 meters (14,459 feet) and encountered four hydrocarbon-bearing intervals. The Triassic TAG formation tested at a stabilized rate of 11,278 barrels of 45.4 degree API gravity liquid per day and 21 million cubic feet of natural gas per day on an equivalent 1.67 inch choke with 802 psia flowing wellhead pressure from 24 meters (79 feet) of net productive sands. The Carboniferous Visean RKF sandstone tested 2,675 barrels of 53.2 degree API gravity liquid per day and 38 million cubic feet of natural gas per day on a 56/64 inch choke with 2,726 psia flowing wellhead pressure from 21 meters (70 feet) of net pay. The well also tested two zones within the Devonian section. The Strunian F1/F2 sands tested at 685 barrels of 54.7 degree API gravity liquid per day and 35 million cubic feet of natural gas per day on a 60/64 inch choke with 2,152 psia flowing wellhead pressure from 5 meters (18 feet) of net pay, while the deeper Emsian F4 sands tested at 13 million cubic feet of natural gas per day on a 48/64 inch choke with 1,340 psia flowing wellhead pressure from 7 meters (23 feet) of net pay. No formation water was recovered during any of these tests.

Bobby S. Shackouls, BR's chairman, president and chief executive officer, commented, "We're extremely excited about these excellent test results which indicate substantial reserve potential in this unexplored area of Block 405. The MLSE-1 well tested a large seismic feature on our block. We are in the process of moving the drilling rig from MLSE-1 to immediately begin drilling MLSE-2, a delineation well on Block 405 approximately 5 kilometers (3.1 miles) to the northeast of our new field discovery. Additional exploratory drilling as well as acquisition of a three-dimensional seismic survey is planned for the southeastern portion of Block 405."

In the western portion of Block 405, a second rig under contract is currently drilling another exploration well, MLW-1. This is BR's first well based on a three-dimensional seismic survey that was acquired over the MLN Field and adjacent areas. MLW-1 is located 16 kilometers (10 miles) west southwest of MLN-1, a previous discovery, and will test both TAG and Devonian targets.

Bobby S. Shackouls commented further, "The encouraging results we have experienced from our two most recent exploratory wells on Block 405, MLN-4 and MLSE-1, demonstrate the significant benefit of our accelerated drilling program in Algeria. We plan a very active drilling program for the remainder of 1998 and expect to drill or participate in at least two additional exploratory wells and five development wells in Algeria this year."

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 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.
