London-based Africa explorer Afren has bought all of Devon Energy’s interests in Angola and Ghana, including a 95 percent stake in the prospective Kheta block and 15 percent in Block 16.

Undrilled deepwater sandstone prospects have been worked up by Devon at Kheta off Ghana, while in Angola, Block 16 offers the Maersk-operated Lower Congo Basin with Miocene and Oligocene “discoveries, prospects, leads and (mapped) play types”, an Afren statement said.

A billion barrels of oil equivalent are expected in place in Block 16.

The Keta block in Ghana is well covered by 3D survey work and reserves are of up to 500 million boe are envisioned. The Mahogany and Hyedua discoveries of the past year bode well for Keta, while Angola Block 16 lies "adjacent and on trend" with 45 significant discoveries, Afren chief exec Osman Shahenshah was quoted as saying.
