Tullow looking to extend prolific deepwater Ghanaian play

Five years ago, Ghana was widely regarded as a high-risk, low-reward deepwater play. Events since have consigned that view to history, with Jubilee, the first of a series of major discoveries, due to come onstream before year-end. Offshore talked to Angus McCoss, exploration director of Tullow Oil in London, which has been instrumental in the transformation, along with US companies Kosmos Energy and Anadarko, and which is now looking to extend the Ghanaian play fairway out to South America.

Tullow has a 49.95 per cent operated interest in Ghana’s Deepwater Tano license, and 22.9 per cent of the adjacent West Cape Three Points (WCTP) license, extending across a total of 2,605 sq km. It is also unit operator of the Jubilee field development, with a 34 per cent interest, while Kosmos Energy is the technical operator. Kosmos, Anadarko, Ghanaian National Petroleum Co. (GNPC), and Sabre are partners in both exploration licenses, with EO Group also present in WCTP.

Between June 2007 and September 2010, Tullow has operated or participated in 15 deepwater exploration and appraisal wells across these permits, in water depths ranging from 1,079-1,428 m (3,540-4,685 ft), with only one failure, Dahoma-1 in WCTP. Aside from Jubilee and the South-East Jubilee extension which includes Mahogany Deep, the company has achieved commercial discoveries in Turonian and Campanian intervals on Tweneboa and Owo in Deepwater Tano, and on Odum in WCTP.
