Deepwater Tano Block

producing Assets

The Deepwater Tano Block is adjacent to the West Cape Three Points Block in the Tano Basin offshore Ghana. Kosmos entered the Block to further expand our position in the basin, capturing a leading position in this 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 as a major discovery and the Tano Basin a new petroleum system .

Kosmos 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 focused on the Enyenra and Ntomme oil fields, utilizing a floating production, storage and offloading (FPSO) vessel.

Production from Tweneboa, Enyenra, and Ntomme (TEN) began in August 2016.
