MILAN, Italy – Eni has completed drilling Sankofa East 2A, the first appraisal well of the Sankofa East oil discovery offshore Ghana.
The location was in 900 m (2,952 ft) water depth in the Offshore Cape Three Points (OCTP) block in the Tano basin, 50 km (31 mi) offshore. The well encountered 23 m (75 ft) of gas and condensate gross pay and 76 m (249 ft) of gross oil pay in good-quality Cretaceous-era sands.
Sankofa East 2A was drilled 8 km (4.9 mi) southwest of the Sankofa East 1X discovery. Following this latest well, Eni estimates in-place oil at about 450 MMbbl with recoverable resources of up to 150 MMbbl. Data acquisition confirmed hydraulic communication in the oil-prone reservoir between the two wells.
Planning is under way on how to commercialize the oil reserves, with engineering studies also continuing for development of the block’s gas reserves in line with a recently signed memorandum of understanding with block partners Vitol, GNPC, and Ghana’s Ministry of Energy.
Eni estimates overall recoverable resources of gas, associated liquids and oil in the OCTP block at roughly 450 MMboe.
