Operating groups led by Kosmos Energy Ltd., Dallas, and Tullow Oil PLC have tested the Akasa-1 discovery on the West Cape Three Points block off Ghana and gauged gas-condensate at the Tweneboa-4 appraisal well on the Deepwater Tano block.
The Akasa-1 exploratory well cut 108 net ft of primarily high-quality, oil-bearing pay in four main Turonian-aged sand packages similar to those found in the Jubilee and Mahogany East areas. Samples recovered from the Akasa-1 well indicate oil of 38° gravity. The well, which went to 12,850 ft in 3,800 ft of water, will be preserved for future use.
After successful appraisal, the group expects Akasa and previous discoveries at Teak to potentially anchor another development on the block.
West Cape Three Points interests are Kosmos and Anadarko Petroleum Corp. 30.875% each, Tullow 26.396%, Sabre Oil & Gas Holdings 1.854%, and Ghana National Petroleum Corp. 10% carried.
Meanwhile, Tweneboa-4 sustained 3,500 b/d of condensate and 30 MMcfd of gas on a drillstem test. Previously, Tweneboa-2 flowed 6,500 b/d of oil and 4.8 MMcfd on a drillstem test. Data from the tests are being used to optimize development plans for the Tweneboa-Enyenra complex. The partnership has mobilized the drillship north to drill an updip appraisal well at Enyenra-3A.
Deepwater Tano interests are Tullow 49.95%, Anadarko and Kosmos 18% each, Sabre 4.05%, and GNPC 10% carried.
