Offshore staff

HOUSTON – Anadarko Petroleum Corp. (NYSE:APC) says its Enyenra-4A appraisal well offshore Ghana encountered oil. The well encountered 105 ft (32 m) of  net oil pay in high-quality sandstone reservoirs, expanding the areal extent of the TEN (Tweneboa, Enyenra, and Ntomme) complex.

The Enyenra-4A well is 4 is (7 km) southwest of the Enyenra-2A and almost 13 mi (21 km) south of the Enyenra-3A well, which defines the northern end of the Enyenra field. The well was drilled to a depth of 13,694 ft (4,174 m) in approximately 6,158 ft (1,878 m) of water. Once operations are complete, the partnership plans to suspend the well and return the drillship, at a later date, to perform a drillstem test at Ntomme-2A.

“With the success of the Enyenra-4A well, we’ve extended this high-quality oil accumulation more than 13 mi (21 km)  from north to south, indicating approximately 2,000 ft (610 m) of continuous oil column,” said Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels.

Anadarko has an 18% working interest in the Deepwater Tano block. Partners in the block include Tullow Oil plc (49.95% working interest and operator), Kosmos Energy (18%working interest), Sabre (4.05% working interest), and the Ghana National Petroleum Corp. (10-percent carried interest).
