HOUSTON – Anadarko Petroleum Corp. says its Itaipu-2 presalt appraisal well offshore Brazil encountered a 58 ft (8 m) gross hydrocarbon column in a carbonate reservoir.
The well, in block BM-C-32 of the Campos basin, was drilled to TD of 16,000 ft (4,877 m) in 4,666 ft (1,420 m) of water.
“The pre-salt Itaipu-2 well is an aggressive step-out from the Itaipu discovery well, which is located 4 mi (7 km) northwest,” said Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels. “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.”
Anadarko holds a 33.3% working interest in BMC- 32. BP operates the block with a 40% working interest and Maersk Oil holds a 26.7% working interest.
Separately, Anadarko also is drilling an appraisal of its postsalt Itauna discovery on block BM-C-29, and plans to spud the Wahoo-4 presalt appraisal well on block BM-C-30 around the end of the year.
