Eni to tie back Block 4 offshore Ghana discovery

Eni SPA will tie-in its new Eban exploration discovery offshore Ghana to the John Agyekum Kufuor FPSO. The well is about 50 km off the coast and about eight km north-west of Sankofa Hub.

Eban-1X is the second well drilled in CTP Block 4 following the Akoma discovery. It was drilled by the Saipem 10000 drillship in 545 metres of water and reached a measured depth of 4,179 metre. The well proved a single light 80 metres thick oil column in a thick sandstone reservoir interval of Cenomanian age, encountering hydrocarbons down to 3,949 metres true vertical depth.

The discovery has been assessed following analysis of 3D seismic datasets and well data acquisition including pressure measurements, fluid sampling, and formation testing.

Pressure and fluid data (oil density and gas-to-oil ratio) and reservoir properties are consistent with the Akoma discovery and nearby Sankofa field. Production testing data show a well deliverability potential estimated at 5,000 b/d similar to producing wells from Sankofa field.

Estimated hydrocarbon in from Sankofa field and the Eban-Akoma complex is now more than 1.1 billion boe.

Eni is operator of the CTP Block 4 joint venture (42.469%) with partners Vitol (33.975%), GNPC (10%), Woodfields (9.556%), and GNPC Explorco (4%).
