Tullow Oil has encountered 27m of net hydrocarbon bearing reservoirs in the Teak-2 exploration well in the West Cape Three Points licence, offshore Ghana.
The exploration well was drilled targeting a fault block between the Jubilee field and the Teak-1 discovery, located 1.8km south-west of the Teak-1 well.
Tullow discovered 6m of net oil and gas pay at the top of good quality Campanian reservoirs, over 100m thick, and another 21m of net hydrocarbon pay, 16m of which is rich gas in the Turonian reservoirs.
Static pressure data suggests the pay potentially forms a gas cap to the Jubilee oilfield.
Future analyses and pressure interference testing will determine hydrocarbon contacts and the extent of these two adjoining fields.
The firm used the Atwood Hunter rig to drill Teak-2 to a total depth of 3,409m in water depths of 885m.
Tullow has a 22.896% interest in the West Cape Three Points licence, along with partners Kosmos Energy, Anadarko Petroleum Sabre Oil & Gas and the Ghana National Petroleum Corporation.
