Italian oil giant Eni SpA has confirmed a discovery of around 450m barrels at its Sankofa East field 50km off the coast of Ghana, boosting the west African nation’s overall oil reserves.

About 150m barrels of Eni’s find will be immediately recoverable, according to the company, which says the result “confirms the commercial standing” of its Ghanaian prospects.
