Incorporating results from the first appraisal well, an Eni-led group is making plans to develop the Sankofa East oil and gas-condensate discovery offshore Ghana after estimating it can recover as much as 150 million bbl of oil equivalent of the estimated 450 million boe in place.
Sankofa East 2A, 8 km southwest of the Sankofa East X1 discovery well on the Offshore Cape Three Points block in the Tano basin 50 km off Ghana, confirmed the extension of the oil accumulation in the Cenomanian sequence.
Sankofa East 2A went to 4,050 m in 990 m of water and cut 23 m of gas-condensate gross pay (17 m net) and 76 m of gross oil pay (32 m net) with 30° gravity oil in good Cretaceous sands.
Engineering studies on developing and commercializing the gas are under way in accordance with principles sanctioned in a memorandum of understanding recently signed by Eni, Vitol Upstream Ghana Ltd., and Ghana National Petroleum Corp. with the Ministry of Energy of Ghana. The MOU focuses mainly on the domestic gas market, in which Eni and partners aim to play a prominent role.
Eni Ghana Exploration and Production Ltd. operates the block with 47.222% interest, Vitol has 37.778%, and GNPC 15% plus an option for a further 5%. Eni operates the OCTP and Keta blocks off Ghana.
