BP PLC and its partners reported the successful drilling of the Itaipu-2 appraisal well on Block BM-C-32 in the presalt play offshore Brazil. The well was drilled to 16,000 ft total depth in 4,660 ft of water in the Campos basin and found a gross petroleum column of 58 net ft of presalt carbonate reservoir.
The appraisal well is an “aggressive step-out” from the Itaipu discovery well, which lies 4 miles to the northwest, said Bob Daniels, senior vice-president, worldwide exploration, Anadarko Petroleum Corp., which is a partner in the block (OGJ Online, Dec. 18, 2009). “The Itaipu-2 well established a fluid contact and appears to have successfully extended the accumulation 120 m 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,” Daniels said.
BP operates Block BM-C-32 with a 40% working interest. Anadarko, through a wholly owned subsidiary, holds a 33.3% interest, and Maersk Oil holds a 26.7% interest.
