Tullow Oil plc (Tullow) has announced that its Teak-1 exploration well in the West Cape Three Points licence offshore Ghana has discovered approximately 73 metres 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.
A statement at the company’s website said in the shallower Campanian-aged reservoirs, the well intersected 6 metres of oil pay in the upper zone and 33 metres of gas pay with an underlying 15 metre 40 degree API oil leg, in the lower zone.
It said in the deeper stratigraphic Turonian-aged reservoirs, the well intersected 14 metres of gas-considerate pay in two separate zones and 5 metres of 32 degree API oil pay in a deeper level.
“The up-dip combination structural and stratigrahic Campanian trap is potentially 50 sq km 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,” it said.
It said the Atwood Hunter rig drilled Teak-1 to a total depth of 3,170 metres of 868 metres. “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,” it said.
Commenting on the new discovery, Angus McCross, Exploration Director, said: “Success in all five of the targeted reservoirs, encountering 73 metres 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 lincence.”
“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,” he said.
Tullow has a 22.896 per cent interest in the West Cape Three Points licence and its partners are Kosmos Energy (Operator) and Anadarko Petroleum Corporation (30.875 per cent each),the E.O Group (3.5 per cent), Sabre Oil & Gas Holdings Ltd. (1.854 per cent) and the Ghana National Petroleum Corporation (GNPC) (10 per cent carried interest ).
