HOUSTON, Dec. 8 -- Kosmos Energy, private Dallas operator, confirmed its 2008 Odum discovery off Ghana, proving the potential of the Campanian play on the West Cape Three Points Block east of giant Jubilee oil field.
The company’s Odum-2 appraisal well cut 66 ft of net hydrocarbon-bearing pay in high-quality stacked sandstone reservoirs over a 597-ft gross interval about 4 km northeast of the Odum-1 discovery well. The Odum discovery is 18 km east of Kosmos Energy’s Mahogany-1 exploration well and Jubilee field (see map, OGJ, Dec. 8, 2008, p. 40).
Odum-2’s 66 ft of net oil pay is in two intervals that appear to be in static pressure communication with the Odum-1 well, Kosmos Energy said. Odum-2 encountered an oil-water contact 190 ft below lowest known oil in Odum-1, extending the known oil column beyond the deepest oil seen in Odum-1.
Reservoir fluid samples recovered indicate the crude to be of 18-19° gravity. The Atwood Hunter semisubmersible drilled Odum-2 to 8,222 ft in 2,677 ft of water.
Odum-2 confirms the second of Kosmos Energy’s four oil and gas discoveries off Ghana, where the company has drilled nine consecutive successful exploration and appraisal wells.
The Atwood Hunter will move to the adjacent Deepwater Tano Block to drill the Tweneboa-2 appraisal well that will evaluate the most recent oil find made by Kosmos Energy and partners. That group is drilling the Mahogany Deep-2 appraisal well using the Aban Abraham drillship.
