The lead operator of the Offshore Cape Three Point (OCTP), Eni has announced a significant oil discovery in Ghana with the potential to produce 700 million barrels of oil equivalent (Mboe).

The company in a statement said the discovery was made on the Eban exploration prospect in Cape Three Points Block 4, offshore Ghana and production testing data show a well deliverability potential estimated at 5,000 barrels of oil per day, similar to the wells already in production from the Sankofa Field.

“The Eban – 1X well is located approximately 50 kilometers off the coast and about 8 kilometers Northwest of Sankofa Hub, where the John Agyekum Kufuor FPSO is located. It was drilled by the Saipem 10000 drilling ship in a water depth of 545 meters and reached a total depth of 4179 meters (measured depth). Eban – 1X proved a single light oil column of approximately 80m in a thick sandstone reservoir interval of Cenomanian age with hydrocarbons encountered down to 3949m (true vertical depth),” the statement said.

“The new discovery has been assessed following a comprehensive analysis of extensive 3D seismic datasets and well data acquisition including pressure measurements, fluid sampling and intelligent formation testing with state-of-the-art technology. The acquired pressure and fluid data (oil density and Gas-to-Oil Ratio) and reservoir properties are consistent with the previous discovery of Akoma and nearby Sankofa field. The production testing data show a well deliverability potential estimated at 5000 bopd, similar to the wells already in production from Sankofa Field.

“The estimated hydrocarbon in place between the Sankofa field and the Eban-Akoma complex is now in excess of 1.1 Bboe and further oil in place upside could be confirmed with an additional appraisal well”.

Fast-track production

The statement further disclosed that due to its proximity to existing infrastructures, “the new discovery can be fast-tracked to production with a subsea tie-in to the John Agyekum Kufuor FPSO, with the aim to extend its production plateau and increase production. The Eban discovery is a testimony to the success of the infrastructure-led exploration strategy that Eni is carrying out in its core assets worldwide”.

The Joint Venture of CTP Block 4 is operated by Eni (42.469%), on behalf of partners Vitol (33.975%), GNPC (10%), Woodfields (9,556%), GNPC Explorco (4,00%).

Eni has been present in Ghana since 2009 and currently accounts for a gross production of about 80,000 barrels of oil per day.
