Anadarko Petroleum Corporation (NYSE: APC) announced the Enyenra-4A appraisal well, located in the Deepwater Tano Block offshore the Republic of Ghana, encountered approximately 105 feet (32 meters) of net oil pay in high-quality sandstone reservoirs, expanding the areal extent of the TEN (Tweneboa, Enyenra and Ntomme) complex.
"With the success of the Enyenra-4A well, we've extended this high-quality oil accumulation more than 13 miles (21 kilometers) from north to south, indicating approximately 2,000 feet (610 meters) of continuous oil column," said Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels. "We've seen strong evidence of static communication among the wells in the field and plan to continue working to affirm connectivity, while advancing this future mega project toward a Plan of Development and sanctioning."
The Enyenra-4A well is located approximately 4 miles (7 kilometers) southwest of the Enyenra-2A and almost 13 miles (21 kilometers) south of the Enyenra-3A well, which defines the northern end of the Enyenra field. The well was drilled to a depth of approximately 13,694 feet (4,174 meters) in approximately 6,158 feet (1,878 meters) 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.
Anadarko has an 18-percent working interest in the Deepwater Tano Block. Partners in the block include Tullow Oil plc (49.95-percent working interest and operator), Kosmos Energy (18-percent working interest), Sabre (4.05-percent working interest) and the Ghana National Petroleum Corporation (10-percent carried interest).
