Addax drilled two dry hole exploration wells on the Odiong and Tali prospects but then had success with a Tali sidetrack.

The original Tali well was drilled to a depth of 2900 metres with its sidetrack establishing a gross hydrocarbon column of 79 feet, comprising 62 feet of oil and 17 feet of gas.

The Geneva-based operator believes that Tali "may be developed in the future together with existing oil discoveries in an overall field development".
