BowLeven has encountered a prospective hydrocarbon column at the Sapele-1 exploration well in the Douala Basin, off the coast of Cameroon.

Bowleven plans to carry out appraisal drilling and well testing to further evaluate Tertiary discoveries.

The firm will bring in an additional rig by the end of this month to drill four wells on the Etinde Permit.

Bowleven chief executive Kevin Hart said that the discovery highlights the significance and potentially transformational nature of this play.
