Anadarko Petroleum declared the Jupiter-1 discovery well, offshore Sierra Leone, encountered 98 net feet (30 meters) of hydrocarbon pay in Upper Cretaceous-age reservoirs.

Additionally, the company announced its latest appraisal well offshore Mozambique, Lagosta-3, encountered approximately 577 total net feet (176 meters) of natural gas pay in multiple zones.

"The Jupiter-1 well is a successful test that has been preserved for possible re-entry, as the area will likely require additional evaluation," said Bob Daniels, Anadarko Sr. Vice President, Worldwide Exploration. "We are planning potential drillstem testing (DST) in the basin, following the Mercury appraisal well, to provide additional information regarding reservoir quality and deliverability."

The Jupiter-1 well in block SL-07B-11 is located more than 15 miles (25 kilometers) from the Mercury-1 discovery well. Jupiter was drilled to a total depth of approximately 21,212 feet (6,465 meters) in water depths of approximately 7,215 feet (2,199 meters) in the Sierra Leone/Liberia Basin. Once operations are complete at Jupiter, the company will mobilize the rig to drill the Mercury-2 appraisal well in the same block.

Anadarko operates the block with a 55-percent working interest. Co-owners in the block include Repsol Exploracion Sierra Leone, S.L. (25-percent working interest) and Tullow Sierra Leone B.V. (20-percent working interest).
