Afren Nigeria appraisal well a success

Afren says its Okwok-9 appraisal well offshore south-east Nigeria found 10 ½ m of net pay in the D2 reservoir and tested 31º API oil at sustained rates. The company now is considering stand-alone development versus tieback to Ebok. Okwok-9 reached TD of 2,464 m and the flow test lasted 48 hours and was shut-in to test pressure build-up, which equalled initial reservoir pressure. Other log and test data analysis is under way to establish whether the Okwok field is commercial.
