African explorer Afren has hit more pay with its Ebok North Fault exploration well offshore south-east Nigeria.

Afren said the Ebok North Fault well has encountered 370 feet (112 metres) of net oil pay in the same Tertiary reservoir as that found in the main Ebok development, after the well was drilled to a  depth of 4,320 ft (1,317 m).

Drilled by the Transocean Active 1X jackup, the well was targeting a separate fault block north of the main Ebok field and estimates suggest the new stepout well has discovered another 100 million barrels of oil.

The well has been suspended while Afren and its partner Oriental Energy Resources consider the optimal development for the new discovery: Afren indicates that this will most likely include using existing production, storage and offtake infrastructure at the main Ebok field, and could involve the early drilling of new production wells from an existing wellhead platform at Ebok West Fault block, followed by a full field development of Ebok NFB.

“The proximity of Ebok NFB to existing infrastructure at the main Ebok field production hub means that we can quickly monetise these newly discovered volumes”  said Afren chief executive Osman Shahenshah.

Next, the Transocean Adriatic IX rig will start drilling early production wells at the recent Okoro East discovery.
