DALLAS -- The Mahogany-4 appraisal well in West Cape Three Points block, offshore Ghana, has struck oil and gas, according to operator Kosmos Energy. Drilling, wireline logs, and reservoir fluid samples show the well penetrated net hydrocarbon-bearing pay of at least 43 m (141 ft) in high-quality stacked sandstone reservoirs over a gross interval of 258 m (846 ft), the company says. Kosmos has now drilled eight consecutive successful exploration and appraisal wells offshore Ghana.
The Mahogany-4 well encountered a total of 39 m (128 ft) of oil pay and 4 m (13 ft) of wet gas pay stacked in four pools in reservoir sands equivalent to those intersected in previous wells, the company says. Reservoir fluid samples recovered indicate an oil gravity of approximately 35° API. This well and the Mahogany-3 appraisal well have extended the potentially productive area on the West Cape Three Points block, according to Kosmos.
The semisub Atwood Hunter drilled the well to a total depth of 3,680 m (12,074 ft) in a water depth of 1,078 m (3,537 ft). Following the drilling of the Mahogany-4 well, the rig will drill a development well in the Jubilee field. It will then drill two wells to appraise the Odum and Tweneboa discoveries.
Kosmos and its block partners are currently drilling the Mahogany Deep-2 appraisal well, southwest of the Mahogany-4 well, using the drillship Aban Abraham.
The partners are executing a phased development plan for the Jubilee field, which is on the West Cape Three Points block and adjacent Deepwater Tano block. The Jubilee partners expect first oil production to begin in late 2010. The designed production capacity of phase one is 120,000 b/d of crude.
