Eni, an Italian oil and gas corporation, has announced a significant oil discovery off the coast of Ghana on the Eban exploration area in CTP Block 4. According to preliminary estimations, the Eban–Akoma complex has a potential of 500 to 700 Mboe.

Following the Akoma discovery in CTP Block 4, the Eban – 1X well is the second well drilled in the block. It’s about 50 kilometres off the coast and 8 kilometres northwest of Sankofa Hub, home to the John Agyekum Kufuor FPSO. The Saipem 10000 drilling ship drilled it in 545 metres of water, reaching a total depth of 4179 metres (measured depth).

According to Eni: “The new discovery has been assessed following 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.”

Eni (42.469%) manages the CTP Block 4 Joint Venture on behalf of partners Vitol (33.975%), GNPC (10%), Woodfields (9.556%), and GNPC Explorco (4%).
