HOUSTON, June 6
– A Kosmos Energy group said its Banda-1 exploratory well in the West Cape Three Points license off Ghana discovered light oil in thick but poor quality Cenomanian-aged turbidite reservoirs.

Banda-1 is the group’s first wildcat designed specifically to investigate Cenomanian potential on the block. Finding light oil in a thick sandstone package is encouraging, and the group will integrate the well results into the regional geologic model to reevaluate the remaining potential in other prospects at this stratigraphic level on its acreage.

Banda-1, 9.6 km southeast of the Odum discovery in the eastern part of the license, encountered the Cenomanian turbidites in a gross vertical interval of 300 m that contains more than 100 m of low-porosity sandstone and 3 m of 40° gravity oil pay.

Banda-1 went to 4,580 m in 921 m of water. It will be suspended for potential future use and the rig will move to resume drilling the Makore-1 well, which is targeting Turonian-age reservoirs in the south of the West Cape Three Points license. Another rig drilled the upper section of Makore in April.

Kosmos Energy operates West Cape Three Points with 30.875% interest. Anadarko Petroleum Corp. has 30.875%, Tullow Oil PLC has 22.896%, E.O. Group 3.5%, Sabre Oil & Gas Holdings Ltd. 1.854%, and the Ghana National Petroleum Corp. 10% carried interest.
