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 May 2013 the approval of the TEN Plan of Development.
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 focusing on Jubilee-play Late Cretaceous turbidite fan systems.
