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 and in May 2013 the approval of the TEN Plan of Development.

In 2013, a number of significant high-impact exploration wells tried to replicate in Côte d'Ivoire and Mauritania the success seen in Ghana from the Jubilee-like late Cretaceous turbidite fan systems. Tullow expects a result from the Tapendar well in Mauritania in 1H 2014 and the drilling of the Fatala well in Guinea is expected to commence in April 2014.

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 these exploration wells to add to the success of the 2013 appraisal programme.
Mauritania Block 7 Frégate (Scorpion) 36.15% 293 106 Completed
  C- 10 Tapendar 59.15% (op) 105 62 In progress
  C- 6 Sidewinder 88% (op) 276 243 TBC
Following the play opening Frégate-1 well, two further Cretaceous tests on the Tapendar and Sidewinder prospects are planned.
We plan to follow up on any success with the re-prioritisation of the 80 prospects in our inventory and the launching of extensive basin drill-out campaigns.
Guinea Guinea Offshore Fatala 40% (op) 259 104 Force Majeure
3D seismic acquired, processed & interpreted over deep water turbiditic Fatala and Sylli prospects. Fatala is scheduled for drilling Q2 2014, with very significant follow-up prospectivity recognised to the east. Potential for further 3D seismic acquisition in 2014 across remaining leads and prospects.
