Successful appraisal well in the pre-salt of block BM-C-32 in Brazil

The Consortium of block BM-C-32 in Brazil, operated by BP - British Petroleum (NYSE:BP,LON:BP) that owns 40%, Anadarko (NYSE:APC,FRA:AAZ), with 33.3% and Maersk Oil (CPH:MARSK B,PINK:AMKBF) with the remaining 26.7%, announced today (November 9, 2011) 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 4,877 meters in 1,420 meters of water, and encountered a gross petroleum column of approximately 18 meters in a pre-salt carbonate reservoir.

According to Anadarko’s press release of December 17, 2009, originally this consortium was operated by Devon Energy Corp. (NYSE:DVN) with 40% working interest, Anadarko with 33.3% and SK Energy Co., Ltd. (Private) holds the Remaining 26.7% working interest.

“The pre-salt Itaipu-2 well is an aggressive stepout 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 we will increase our previous resource estimates for the field. We are very pleased with these results and look forward to continuing our activity on the block.”
