Appraisal well offshore Ghana finds light oil

Offshore staff

Anadarko Petroleum Corp.’s Ntomme-2A appraisal well offshore Ghana found 128 ft (39 m) net of light oil (35ºAPI) pay.

The Ntomme-2A well is 2.8 mi (4.5 km) south of the Tweneboa-3 side track, in 5,675 ft (1,730 m) of water. The well was drilled to a depth of approximately 12,810 ft (3,905 m). Once operations are complete, the partnership plans to install gauges in the Tweneboa-3 side track prior to a planned drillstem test at Ntomme-2A.

“Finding a significant light oil accumulation is an excellent result that enhances the value of the Greater Tweneboa, Enyenra, and Ntomme (TEN) complex, as we now estimate oil makes up the majority of the resource in place,” said Anadarko Sr. Vice President, Worldwide Exploration, Bob Daniels.

“Our 3D seismic modeling, coupled with the pressure data collected from the Ntomme-2A and Tweneboa-3 side track wells, indicates the potential for an oil column of more than 400 ft (122 m) below the gas/condensate accumulation encountered in the Tweneboa-3 side track well. The partnership plans to incorporate this new information into its ongoing program as we advance the development of the TEN complex.”

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 Oil & Gas Holdings Ltd (4.05% working interest) and the Ghana National Petroleum Corp. (10% carried interest).
