Deepwater Tano Block

Near-term Developments

The Deepwater Tano Block is adjacent to the West Cape Three Points Block in the Gulf of Guinea's Tano Basin offshore Ghana. Kosmos entered the Block to further expand our position in the basin, capturing a leading position in the Late Cretaceous play opportunity. An appraisal well of the significant Jubilee field discovery was drilled on the Deepwater Tano block in 2007, confirming the field and the Tano Basin as a major discovery and new petroleum system, respectively.

The company and partners discovered the significant Tweneboa gas condensate accumulation in 2009, followed by the Enyenra oil field in 2010. Further drilling success resulted in the discovery of oil at the Ntomme field and oil and gas-condensate at Wawa in 2012. Initial development of the discoveries on the Deepwater Tano block is focused on the Enyenra and Ntomme oil fields, utilizing a floating production, storage and offloading (FPSO) vessel. The Deepwater Tano companies have submitted the declaration of commerciality and Plan of Development to the government of Ghana for approval. The FPSO concept anticipates 80 thousand barrels per day of production initially, with the potential for expansion over time. First production from the development is anticipated approximately 30-36 months following approval of the Plan of Development.
