LONDON, June 19 -- Anadarko Petroleum Corp. and its partners have discovered light oil with the Mahogany-1 exploration well drilled on deepwater West Cape Three Points block off Ghana. The discovery, a Santonian turbidite stratigraphic trap, opens a new play fairway in the Tano basin.

Mahogany-1 encountered a 885-ft gross hydrocarbon column with 312 ft of net stacked pay in a Cretaceous sandstone reservoir. The well has so far reached 12,083 ft and is aiming for a TD of 13,780 ft. An Anadarko spokesman told OGJ that the well was targeting a Cretaceous formation. West Cape Three Points block lies in 4,330 ft of water.

Once the partners hit TD, they will suspend the well pending further evaluation and appraisal drilling.

Mahogany-1 is being drilled by the Belford Dolphin deepwater drillship, which is under long-term contract to Anadarko. After finishing that well, Anadarko will use it to drill the Sota-1 well on Block 4 off Benin, in which it holds a 40% interest and is also the operator. Belford Dolphin will then move to the Gulf of Mexico to drill additional tests in Anadarko's 2007 exploration program.

Anadarko is the technical operator of the well with a 30.875% interest. Kosmos Energy is the block operator and holds a 30.875% stake. Other partners are Tullow Ghana Ltd. 22.896%; Sabre Oil & Gas Ltd. 1.854%, and Ghanaian oil and gas company E.O. Group 3.5%.

Ghana National Petroleum Corp. will be carried through the exploration and development phases with a 10% participating interest.
