News Release Details

DALLAS--(BUSINESS WIRE)--May. 30, 2013-- Kosmos Energy Ltd. (“Kosmos”) (NYSE: KOS) announced today that the Government of Ghana has formally approved the Plan of Development (“PoD”) for the Tweneboa-Enyenra-Ntomme (“TEN”) discoveries. Approval of the PoD paves the way for Kosmos and its co-venturers, Tullow Oil, Anadarko Petroleum, PetroSA, and the Ghana National Petroleum Corporation to proceed with the development of the discoveries, with associated major contracts expected to be finalized and subsequently awarded.

The TEN project is located in the Deepwater Tano Block, 60 kilometers (37 miles) offshore Ghana and approximately 30 kilometers (18 miles) west of the Jubilee Field. The TEN project is expected to deliver first oil in 2016, with a plateau production rate of 80,000 barrels of oil per day. Future development of gas resources at TEN is anticipated following the commencement of oil startup.

Development of TEN will include the drilling and completion of up to 24 development wells, with half of the wells designed as producers and the remainder for water and gas injection to support ultimate field recoveries. The wells will be connected through subsea infrastructure to a Floating, Production, Storage, and Offloading vessel (FPSO), moored in approximately 1,500 meters (4,920 feet) of water.

Darrell McKenna, Chief Operating Officer, commented, “The approval of the TEN Plan of Development by the Government of Ghana is a positive milestone towards first production from the country’s second major offshore development.”

Following approval of the TEN PoD, Kosmos holds a 17 percent participating interest in the Deepwater Tano Block. The Company’s co-venturers include Tullow Oil plc as operator (47.18 percent), Anadarko Petroleum (17 percent), Sabre Oil & Gas Holdings Ltd., a wholly owned subsidiary of Petro SA (3.82 percent), and the Ghana National Petroleum Corporation (15 percent).
