HOUSTON, May 8 -- ChevronTexaco Corp. said two Tahiti appraisal wells confirmed hydrocarbon reservoirs found in the Tahiti discovery well in the deepwater Gulf of Mexico and one appraisal well encountered more than 1,000 ft of net pay.
A production test of the discovery well is planned for the first quarter of 2004.
Last year, Tahiti No. 1 on Green Canyon Block 640, 190 miles southwest of New Orleans, show total net pay of more than 400 ft in what ChevronTexaco called a "significant" accumulation for the deepwater gulf (OGJ Online, Apr. 3, 2002).
The appraisal wells were drilled simultaneously on Green Canyon Blocks 596 and 640 in slightly more than 4,000 ft of water. Each was a vertical well with a sidetrack.
The appraisal wells confirmed initial estimates of 400-500 million bbl of reserves, and appraisal drilling is continuing.
ChevronTexaco operates the Tahiti prospect with 58% interest. Partners are EnCana Gulf of Mexico LLC, 25%, and Shell Exploration & Production Inc., 17%. EnCana Gulf of Mexico is a subsidiary of the Calgary-based EnCana Corp.
