African Successes for Afren and Tullow

Two Africa-focused companies announced upstream successes Wednesday, with Afren beginning production at an extension to its Okoro field in Nigeria and Tullow confirming that it found oil at its Twiga South well in Kenya.

Afren announced that it has successfully begun production from its Okoro field extension, offshore south-east Nigeria, at a stabilized rate of 5,000 barrels of oil per day (bopd) of 38-degree API oil. This has increased the total output from the Okoro area to approximately 21,500 bopd.

"I am delighted that we have commenced early production at the Okoro Field Extension, just nine months after the initial discovery. This is clear evidence that we are creating tangible value and volume growth from our ongoing exploration drilling campaign, and further testament to the Afren team's fast track development capabilities," Afren Chief Executive Osman Shahenshah commented in a statement.

On the other side of the continent, Tullow confirmed that its Twiga South-1 exploration well in block 13T, onshore Kenya, has successfully encountered oil, although drilling is ongoing.

The Twiga South-1 structure is the second prospect to be tested as part of a multi-well drilling campaign in Kenya and Ethiopia and is the first discovery in block 13T. Tullow, which is the operator of the well with a 50-percent interest, said that it expects to announce drilling result during early November.
