Italian firm Eni and its partners have made oil discovery at the Eban – 1X well in Cape Three Points Block 4 (CTP-Block 4) offshore Ghana.

Located on the Eban exploration prospect and approximately 50km off the coast, the Eban – 1X is the second well drilled in the block following the Akoma discovery.

The Eban – 1X well is located about 8km north-west of Sankofa Hub, where the John Agyekum Kufuor floating production storage and offloading (FPSO) is deployed.

According to preliminary estimates, the Eban-Akoma complex has reserves ranging between 500-700 million barrels of oil equivalent in place (Mboe).

Eni said that the Eban – 1X well, which was drilled using Saipem 10000 drilling ship to a total depth of 4179m, proved approximately 80m single light oil column in a thick sandstone reservoir interval of Cenomanian age.

According to production testing data, well deliverability potential is estimated at 5,000 barrels of oil per day. This is similar to the producing wells in the Sankofa Field.

Additionally, the hydrocarbon in place between the Sankofa field and the Eban-Akoma complex is now estimated at more than 1.1Bboe.

With an additional appraisal well, the partners intend to confirm further oil in place.

Eni said in a statement: “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.”

Eni is the operator of CTP-Block 4 with a 42.469% stake. Other partners in the block include Vitol (33.975%), GNPC (10%), Woodfields (9.556%), GNPC Explorco (4%).

Elsewhere in Ghana, TechnipFMC TechnipFMC secured an integrated engineering, procurement, construction and installation (iEPCI) contract from Tullow Ghana for the Jubilee South East offshore development project.

The Jubilee South East is an extension to the Jubilee deepwater field.

The contract involves the supply and installation of all major subsea equipment, including manifolds and associated controls, flexible risers and flowlines, umbilicals, and structures.
