Kosmos' Appraisal Reveals Non-Commercial Results Offshore Ghana

Kosmos Energy announced results from the Teak-4A appraisal well, located in the West Cape Three Points Block, offshore Ghana. Located 3.8 miles (6.1 kilometers) northwest of the Teak-1 discovery well, the Teak-4A well was targeting the stratigraphic extension of the Teak discovery area. The well encountered thin, non-commercial reservoirs and is being plugged and abandoned. Kosmos and partners have begun integrating well results into the Teak field model to determine forward appraisal and development plans.

The rig Atwood Hunter (DW semisub) drilled Teak-4A to a total depth of 9,348 feet (2,850 meters) in water depth of 1,817 feet (554 meters). Following the completion of operations at the Teak-4A well, the drilling rig will set gauges at the Teak-2A well and perform a drill stem test at the Akasa oil discovery on the West Cape Three Points Block.

Kosmos Energy is the operator of the West Cape Three Points Block with a 30.875 percent interest. The Company's partners include Anadarko Petroleum Corporation (30.875 percent), Tullow Oil plc (26.396 percent), Sabre Oil & Gas Holdings Ltd. (1.854 percent), and the Ghana National Petroleum Corporation (10 percent carried).
