Kosmos announced that the company's Banda-1 exploration well has discovered oil offshore the Republic of Ghana on the West Cape Three Points Block. The results of drilling, wireline logs and reservoir fluid samples show the Banda-1 well penetrated net oil-bearing pay of 3 meters (10 feet). Oil samples recovered from the Cenomanian-age reservoir indicate oil of approximately 40 degrees API gravity.

The Banda-1 discovery opens a new play fairway not previously encountered on the West Cape Three Points Block or adjacent Deepwater Tano Block. The Paradise-1 exploration well, recently drilled by Hess, successfully penetrated a hydrocarbon-bearing, equivalent-age reservoir. The Paradise-1 well is located 32 kilometers (km) (20 miles) southwest of the Banda-1 well location. The Banda-1 well also was designed to test the Upper Campanian interval, which was water bearing. Additional technical evaluation will be required to analyze the impact and extent of this new play discovery, which is deeper than existing Campanian and Turonian discoveries on Kosmos' Ghana blocks.

The Atwood Hunter semi-submersible rig drilled the Banda-1 well in a water depth of 921 meters (3,021 feet) to a total depth of 4,580 meters (15,022 feet) in the eastern portion of the West Cape Three Points Block. The well is located 28 km (17 miles) east of Kosmos' Mahogany-1 exploration well that discovered the Jubilee oil field in 2007.

Tullow's Exploration Director Angus McCoss commented, "The Jobi-East-1 and Mpyo-3 well results mark an excellent start to this next phase of our exploration and appraisal campaign in the Lake Albert Rift Basin. We look forward to many more exciting wells as we endeavor to determine the total oil resource base which will underpin the basin-wide development preparations currently in progress."
