Eni has announced 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.
According to a statement, preliminary estimates place the potential of the Eban–Akoma complex between 500 and 700 Mboe in place.
The Eban – 1X well is located approximately 50 kilometres, off the coast and about 8 kilometres Northwest of Sankofa Hub, where the John Agyekum Kufuor FPSO is located.
The company said in the statement 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 discovery it said 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, adding 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 also show a good deliverability potential estimated at 5000 bopd, similar to the wells already in production from the Sankofa field.
The estimated hydrocarbon in place between the Sankofa field and the Eban-Akoma complex is now more than 1.1 Bboe and further oil in place upside down could be confirmed with an additional appraisal well.
Due to its proximity to existing infrastructures, the discovery the statement noted can be fast-tracked to production with a subsea tie-in to the John Agyekum Kufuor FPSO, to extend its production plateau and increase production.
The Eban discovery, it pointed out, 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 Explorer (4,00%).
Eni has been present in Ghana since 2009 and accounts currently for a gross production of about 80,000 barrels of oil equivalent per day.
