Tullow Oil has said that it's Tweneboa, Enyenra, and Ntomme fields development, offshore Ghana, known as TEN is progressing well, and is over 50 percent complete. It is expected to produce first oil in mid-2016, as originally planned.  The development includes the drilling and completion of up to 24 development wells which will be connected through subsea infrastructure to a floating, production, storage, offloading (FPSO) vessel.  The conversion of what will be Ghana’s second FPSO continues on schedule, and the overall gross capex cost of the development remains at $4.9 billion.

Tullow to invest $5 million in TEN in 2016
Tullow Ghana Limited will spend about $5 million as capital expenditure into the Tweneboa, Enyena and Ntomme (TEN) project in Ghana by 2016. Tullow has already drilled two developmental wells after securing the West Leo rig. It is expected that enhanced seismic survey will further enhance well placement. Tullow is in the process of converting the Centennial Jewel tanker into a Floating Production Storage Offtake (FPSO) in Singapore. The TEN fields is within an estimated area of 430 square kilometres, about 20 KM west of the Jubilee Field. The TEN fields have estimated reserves of 140 to 337 million barrels and gas reserves of about 128 to 399 billion cubic feet. Nominal nameplate capacity is estimated at 80,000 standard barrels of oil per day while oil storage will be 1.7 million barrels. The gas processing compression capacity is put at 170 million standard cubic feet per day.

The Ghanaian government has also indicated that the country could expand its reserves up to 5 billion barrels (790,000,000 m3) of oil in reserves within a few years. The southern part of  Ghana is believed to have up to 5 billion barrels (790,000,000 m3) to 7 billion barrels (1.1×109 m3) of petroleum in reserves,  which is the sixth largest in Africa and the 25th largest reserves in the world and the south alone has up to 4 trillion cubic feet of natural gas in reserves.
