Eni Strikes Oil With Eban Well Off Ghana
New find in CTP Block 4 boosts reserve potential to as much as 700 million BOE.
Eni has struck a significant oil discovery on the Eban exploration prospect in CTP Block 4, offshore Ghana. The Eban‑1X well is the second well drilled in CTP Block 4, following the Akoma discovery. Preliminary estimates place the potential of the Eban-Akoma complex between 500 and 700 million BOE in place.
The Eban-1X well is located approximately 50 km off the coast and about 8 km northwest of Sankofa Hub, where the John Agyekum Kufuor FPSO is located. It was drilled by drillship Saipem 10000 in a water depth of 545 m and reached a total depth of 4179 m. The well encountered a single light-oil column of about 80 m in a thick sandstone reservoir interval of Cenomanian age with hydrocarbons encountered down to 3949 m.
Production-testing data show a well deliverability potential estimated at 5,000 B/D of oil, similar to the wells already in production from the Sankofa field.
The estimated hydrocarbons in place between the Sankofa field and the Eban‑Akoma complex is now in excess of 1.1 billion BOE and further oil-in-place upside could be confirmed with an additional appraisal well.
Because of its proximity to existing infrastructure, the new discovery can be fast-tracked to production via a subsea tie-in to the John Agyekum Kufuor FPSO, with the aim to extend its production plateau and increase production.
CTP Block 4 is operated by Eni (42.469%) on behalf of partners Vitol (33.975%), GNPC (10%), Woodfields Energy Resources Ltd. (9.556%), and GNPC Explorco (4%).
