TotalFinaElf makes 10th find on Angolan offshore block

France's TotalFinaElf SA says it has made a 10th 'promising' deepwater oil discovery on Block 17 off Angola. On test, Perpetua-1, drilled in the eastern portion of the block in 795 m of water, flowed at a rate of 8,740 b/d of 20� gravity oil.

France's TotalFinaElf SA says it has made a 10th "promising" deepwater oil discovery on Block 17 off Angola. On test, Perpetua-1, drilled in the eastern portion of the block in 795 m of water, flowed at a rate of 8,740 b/d of 20� gravity oil.

"This positive result will be followed by further geological and engineering studies in order to appraise the newly discovered structure," said TotalFinaElf.

The well is about 33 km east of the Tulipa find, discovered in 1999, and 35 km east of Dalia, found in 1997. The TotalFinaElf-led group's other discoveries on the block are Girassol, Rosa, Lirio, Orquidea, Cravo, Camelia, and Jasmin.

TotalFinaElf is operator of Block 17, with a 40% interest; ExxonMobil Corp. owns 20%; BP, 16.67%; Statoil AS, 13.33%; and Norsk Hydro ASA, 10%.

Paralleling continued exploration on the block will be development of Girassol field, the first discovery made on Block 17, in 1996. Girassol development will entail subsea wells tied back to a floating production, storage, and offloading vessel (OGJ, May 8, 2000, p. 53). Production is scheduled to begin in the second half of 2001, and output is expected to plateau at about 200,000 b/d for 5-6 years, according to the operator.

Perpetua-1 is the 12th well drilled on Block 17 and the 10th oil discovery. Meanwhile, ExxonMobil and partners have made eight oil finds on nearby Block 15. These and other oil discoveries in the area make West Africa in general, and the deep water off Angola in particular, one of the world's hottest areas for exploration.
