The well was drilled by the Atwood Hunter rig to a total depth of 3,988mt in a water depth of 1,149mt. The well is located approximately 62km offshore and about 7km southeast of the Mahogany-1 well, the Jubilee discovery well.
The results of drilling, wireline logs and reservoir fluid samples indicate that the well entered to a total net oil pay of 23mt in sandstone reservoirs over a gross interval of 51mt. Reservoir fluid samples recovered 28-32 degree API oil and pressure data have confirmed reservoir communication with the previously drilled Mahogany-4 well.
The rig will now leave Ghana to work for another operator and will return in the fourth quarter of 2010 on a planned nine-month drilling program in the West Cape Three Points license.
Mahogany-5 completes the appraisal of the area and follows successes at the Mahogany-3, Mahogany-4 and Mahogany Deep-2 wells. Geoscience and engineering studies are continuing to refine the potential resource range and advance development planning activities for this area.
Angus McCoss, exploration director of Tullow, said: “We have now encountered oil in four out of five wells in the exploration and appraisal program in the area immediately to the southeast of the Jubilee Field.
“Future exploratory drilling in the West Cape Three Points license, including the adjacent Teak, Dahoma-Updip and South Central Channel prospects, aims to discover even more hydrocarbons to further enhance the commercial development of this license.”
Tullow has a 22.896% interest in the West Cape Three Points license, which is operated by Kosmos Energy.
