LONDON -- Kosmos Energy’s run of successes in its West Cape Three Points license offshore Ghana has been broken, with its latest effort encountering water-bearing reservoirs.
The Dahoma-1 exploration well was drilled by the Atwood Hunter 11 km (6.8 mi) south of Mahogany-3 to explore a down-dip satellite prospect in the southeast Jubilee area, outside the main Jubilee Unit Area.
According to partner Tullow Oil, the well intersected 30 m (98.4 ft) of good-quality sandstone reservoir below a possible oil-water contact, and some indications of oil migration suggest potential for oil trapped up-dip.
Dahoma-1 was drilled to a total depth of 4,390 m (16,174 ft) in water depths of 1,564 m (5,131 ft). The Atwood Hunter will next drill Mahogany-5 to appraise the up-dip oil accumulations eastwards of Mahogany-3.
Tullow says it plans a comprehensive drilling program offshore Ghana over the remainder of this year and into 2011, targeting both lower-risk and high-impact exploration and appraisal targets. The next high-impact wildcat will be Owo-1, in the Tullow-operated Deep Water Tano license, to be drilled in June by the Sedco 702. This well will target upside potential in the greater Tweneboa fan system.
