Ghana: Eni says well confirms Sankofa strike

By OGJ editors
HOUSTON, Apr. 12
-- An appraisal well has confirmed potential of the Sankofa oil and gas discovery to become the first development of nonassociated gas off Ghana, according to Eni SPA.

The company, operator of the Offshore Cape Three Points license, said the Sankofa 2 appraisal well tested high-quality gas at a constrained rate of 29.5 MMscfd and 52° gravity condensate at a rate of 1,000 boe/d.

Drilled in 864 m of water about 55 km offshore, the well confirmed 35 m of net gas and condensate pay in Cretaceous sands with “excellent reservoir characteristics,” Eni said. The well also encountered a 6 m oil leg, “which will be the object of further studies.”

Vitol Upstream Ghana Ltd. operated the block at the time of the Sankofa 1 discovery in July 2009. The well, about 35 km east of Jubilee oil field, encountered 36 m of net oil and gas pay.

Eni acquired majority stakes in and became operator of the Offshore Cape Three Points and Offshore Cape Three Points South blocks in September 2009 (see map, OGJ, Mar. 15, 2010, p. 34). Interests in both blocks are Eni Ghana Exploration & Production Ltd. 47.22%, Vitol Upstream Ghana 37.78%, and Ghana National Petroleum Corp. 15%.

The Sankofa wells are on a block adjacent and to the east of the West Cape Three Points block, where a group led by Kosmos Energy Corp. recently encountered oil, gas, and condensate pay in the Teak-2 exploratory well east of Jubilee field (OGJ, Apr. 4, 2010, Newsletter).
