Tullow has interests in two exploration licences offshore Ghana where, in 2007, two successful exploration wells discovered the substantial Jubilee field which straddles the boundary between the two blocks; Deepwater Tano and West Cape Three Points.
The Minister of Energy in Ghana formally approved the Jubilee field Phase 1 Development Plan and Unitisation Agreement on behalf of the Government of Ghana in July 2009. The field has continued to ramp up towards capacity production with gross average working interest production for 2014 expected to be around 100,000 bopd.
In March 2009, a further major discovery was made in the Deepwater Tano block. The Tweneboa-1 exploration well discovered a highly pressured light hydrocarbon accumulation. This was followed by the successful Tweneboa-2 well announced in January 2010 which encountered oil and gas-condensate 6km south of the original discovery. Since then, a successful E&A campaign has resulted in the Tweneboa-Enyenra-Ntomme (TEN) discovery and the Plan of Development was approved by the government in May 2013 with first oil expected in mid-2016.
