In the West and North Africa business unit, Tullow's major exploration success began in 2007 with the first Jubilee field discovery well, Mahogany-1, in Ghana. To date, over 30 E&A wells have been drilled in Ghana. The successful exploration campaign in Ghana led to the major Jubilee field development project and in November 2012 the TEN Plan of Development was submitted to the Government of Ghana.
In 2012, 17 E&A wells were drilled in the region across Ghana, Sierra Leone, Côte d'Ivoire, Gabon and Equatorial Guinea with a 76% success rate. In 2013, a number of significant high-impact exploration wells will be drilled in Côte d'Ivoire and Mauritania focussing on Jubilee-play Late Cretaceous turbidite fan systems. This exploration play was successfully proven across the Atlantic from Ghana in 2011, with the Tullow discovery in French Guiana at Zaedyus-1.
