The well, which tested a different prospect than the company’s Mahogany-1 discovery well, has been suspended as a future development well.

The Odum-1 well encountered a gross oil column of 60m and when drilled in water depths of 955m reached a total depth of 3,386m. The well is located approximately 13km east of the Mahogany-1 well and the Jubilee field.

Kosmos and its block partners used the Songa Saturn drillship to drill the Odum-1 well. When operations on the well are completed, the Songa Saturn will drill a second appraisal well of the Jubilee field as part of the company’s 2008 multi-well appraisal program.

Kosmos and its partners conducted a high-resolution 3D seismic survey of 940sqkm of the Jubilee field and adjacent areas in December 2007 following the company’s announcement of the Mahogany-1 oil discovery in mid-June 2007.

James Musselman, Kosmos chairman and CEO, said: The success of the Odum-1 well and its confirmation of a new, significant oil province in Ghana’s western offshore basin is another momentous event for the Republic of Ghana and Kosmos.
