SAN RAMON, Calif., Dec. 8 /PRNewswire-FirstCall/ -- ChevronTexaco Corporation today announced that its United Kingdom subsidiary and its partners, Statoil, OMV and DONG, have made a significant oil and gas discovery at the offshore Rosebank/Lochnagar well (213/27-1Z) in the Faroe-Shetland Channel.

The well, located in 3,600 feet (1,100 meters) of water and completed on August 30, 2004, encountered two oil and gas accumulations for a total net pay of 169 feet (52 meters) with oil quality ranging from 27-36 degrees API. Non-associated gas was also encountered in the shallower reservoir. The well, which was not tested, has been plugged and abandoned at a total depth of 12,153 feet (3,607 meters). Further drilling will be carried out to fully appraise the find.

George Kirkland, president of ChevronTexaco Overseas Petroleum, said, "This discovery positions the company for continued growth in the region and further underscores our corporate exploration strategy of focusing on core, high-impact opportunities around the world."

Gary Luquette, President and Managing Director for ChevronTexaco Upstream Europe, said, "We are extremely encouraged by the well results. This is an exciting opportunity and endorses our company's continued commitment to exploration in the Atlantic Margin test area and ongoing investment on the UK Continental Shelf." Luquette also noted that the well was drilled with a strong focus on safety and environmental protection by the "West Navigator" drill ship.

In keeping with ChevronTexaco's strong views on environmental stewardship and habitat integrity, the West Navigator's deepwater Remotely Operated Vehicle was used to obtain high quality scientific information before, during and after drilling operations. A public report will be produced on the findings to contribute to the scientific community's ecological understanding of this little known deep water environment.

    Notes to Editors:

    -- Blocks 213/26 & 213/27 were awarded under licence P1026 to
       ChevronTexaco subsidiary, Texaco North Sea U.K. Company (100%), under
       the UK 19th Licensing Round in 2001.
    -- DONG, OMV and Statoil farmed into the licence before the first
       exploration well was drilled.
    -- The drilling location lies in the Faroe-Shetland Channel, close to the
       UK/Faroes median line and approximately 126km from the closest coast
       (Esha Ness on Shetland).
    -- The West Navigator's deepwater Remotely Operated Vehicle (ROV) was used
       to obtain high quality scientific information before, during and after
       drilling operations.  The ROV, fitted with a high resolution video
       camera, enabled the collection of video footage, photographic stills as
       well as a targeted collection of specimens for subsequent
       identification by deepwater scientific experts.  The identification
       process is still underway, but will enable ChevronTexaco to contribute
       to the scientific community's ecological understanding of this little
       known deep water environment.  The results of the survey will culminate
       in a report to be distributed to statutory bodies within the UK and the
       National Museum of Scotland in Edinburgh.
