Anadarko Petroleum Corporation (Anadarko Petroleum) said that the Wahoo #2 (also called Wahoo North) appraisal/exploration well in the Campos basin has encountered more than 90 feet of high-quality net oil pay in the same pre-salt interval as the original Wahoo discovery. The Wahoo #2 appraisal/exploration well is located in block BM-C-30, five miles north and down-dip from the previously announced Wahoo discovery that encountered more than 195 feet of net pay.
Anadarko Petroleum and its partners are continuing to collect data on the Wahoo #2 well and expect to provide an update regarding the field’s estimated resources after reaching total depth and incorporating the data. Following the completion of drilling operations at Wahoo #2, Anadarko Petroleum plans to move the drillship to the original Wahoo discovery well to conduct drillstem testing (DST), and then back to the Wahoo #2 well to conduct another DST in 2010.
The company’s drilling success on the block continues to de-risk additional prospects, and Anadarko Petroleum plans to maintain an active pre-salt drilling schedule with up to two exploration/appraisal wells on BM-C-30 in 2010.
Anadarko Petroleum, through a wholly owned subsidiary, holds a 30% working interest and is the operator of BM-C-30. Devon Energy Corporation holds a 25% working interest, IBV Brasil Petroleo Limitada, a wholly owned subsidiary of Bharat PetroResources Limited and Videocon Industries, holds a 25% working interest and SK Energy Co., Ltd. holds the remaining 20% working interest.
Also in the Campos basin, Anadarko Petroleum and partners are currently drilling the Itaipu prospect in the adjacent BM-C-32 block. The Itaipu well will test a pre-salt geologic feature similar to the adjacent Jubarte field, which is estimated to hold up to two billion barrels of recoverable oil. Anadarko Petroleum holds a 33% working interest in Itaipu.
“The Wahoo North well is confirming all of its objectives, and the early results from the cores and wireline logs in the appraisal section of the well indicate high-quality resources and reservoir rock,” Anadarko Petroleum Senior Vice President Worldwide Exploration, Bob Daniels said. “We have approximately 2,000 feet left to drill before we reach TD (total depth) to test a secondary exploration objective; nonetheless, our activities so far have confirmed the main pay section in the original Wahoo discovery extends at least five miles to the north, and the hydrocarbon accumulation has been extended further down the structure. We believe the results to date increase the potential resources in the prospect area, and from what we’ve seen so far, Wahoo has the characteristics necessary to potentially become our next mega project.”
