Tullow discovers oil and gas with Teak-1 offshore Ghana

Tullow Oil (LSS:TLW) revealed that the Teak-1 exploration well in the West Cape Three Points license offshore Ghana has discovered approximately 73 meters of net hydrocarbons in two Campanian and three Turonian-aged reservoirs. The well was located 4.6 km northeast of the Mahogany-2 well, 2.7 km outside the Jubilee Unit boundary.

In the shallower Campanian-aged reservoirs, the well intersected 6 meters of oil pay in the upper zone and 33 meters of gas pay with an underlying 15 meter 40 degree API oil leg, in the lower zone. In the deeper stratigraphic Turonian-aged reservoirs, the well intersected 14 meters of gas-condensate pay in two separate zones and 5 meters of 32 degree API oil pay in a deeper level.

The up-dip combination structural and stratigraphic Campanian trap is potentially 50 sqkm in area and will be the subject of further appraisal activity. Interpretation of the potential extent of each of the deeper Turonian zones is ongoing. 

“Success in all five of the targeted reservoirs, encountering 73 meters of total net pay, is an excellent outcome for the Teak-1 well and a great start to our 2011 multi-well exploration campaign in the West Cape Three Points license,” said Angus McCoss, exploration director for Tullow. “The significant potential of this discovery, up-dip of Jubilee, will be appraised during 2011 and 2012 once the current drill-out campaign has been completed.”

The Atwood Hunter rig drilled Teak-1 to a total depth of 3,170 meters in water depths of 868 meters. On completion of operations, the well will be suspended for future use and the rig will move to drill the Teak-2 well which is targeting Campanian and Turonian age reservoirs in a separate fault block between the Teak discovery and the Jubilee field.

Tullow has a 22.896% interest in the West Cape Three Points license and its partners are Kosmos Energy (Operator) and Anadarko Petroleum Corporation (30.875% each), the E.O.Group (3.5%), Sabre Oil & Gas Holdings Ltd (1.854%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).
