Anadarko Petroleum Corporation today announced the successful Itaipu-2 pre-salt appraisal well, located in block BM-C-32 in the Campos Basin offshore Brazil. The well was drilled to total depth of approximately 16,000 feet (4,877 meters) in 4,660 feet (1,420 meters) of water, and encountered a gross petroleum column of approximately 58 net feet (18 meters) in a pre-salt carbonate reservoir.
“The pre-salt Itaipu-2 well is an aggressive step-out from the Itaipu discovery well, which is located 4 miles (7 kilometers) northwest,” Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels said. “The Itaipu-2 well established a fluid contact and appears to have successfully extended the accumulation 120 meters downdip from the discovery. Accordingly, the appraisal well significantly increases the areal extent of the vast Itaipu field, and we believe incorporating the data from both the appraisal well and the original discovery well will increase our previous resource estimates for the field. We are very pleased with these results and look forward to continued activity on the block.”
Anadarko, through a wholly owned subsidiary, holds a 33.3-percent working interest in BM-C-32. BP operates the block with a 40-percent working interest and Maersk Oil holds a 26.7-percent working interest.
Separately, Anadarko also is currently drilling an appraisal of its post-salt Itauna discovery on block BM-C-29, and plans to spud the Wahoo-4 pre-salt appraisal well on block BM-C-30 around the end of the year.
