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 35 E&A wells have been drilled in Ghana. The successful exploration campaign in Ghana led to the major Jubilee field development project which came on stream in November 2010 and in May 2013 the approval of the TEN Plan of Development with first oil on track for mid-2016.

Over the past few years, a number of significant high-impact exploration wells have been drilled in Sierra Leone, Liberia, Côte d'Ivoire and Mauritania trying to replicate the success seen in Ghana from the Jubilee-like late Cretaceous turbidite fan systems. Unfortunately these campaigns have not resulted in the same level of success seen in Ghana and whilst a significant opportunity remains in Mauritania, exploration acreage has been relinquished elsewhere.

In addition to our planned exploration wells, Tullow’s exploratory appraisal drilling in Gabon has a very good track record of replacing reserves and sustaining production. We expect this exploration well to add to the success of the 2013 appraisal programme.

The Mauritania exploration programme continues with the drilling of Kibaro or Lamina on the shelf area of Block C10 in 2015.

3D seismic acquired, processed & interpreted over deep water turbiditic Fatala and Sylli prospects. Fatala is estimated to spud between late 2014 and mid 2015, with significant follow-up prospectivity identified. Once the current issues regarding the licence that were detailed in March 2014 have been resolved a more specific spud date will be confirmed.
