2012 Exploration and appraisal wells
2012 Success rate
In January 2009, Tullow farmed in to three blocks offshore Liberia with a total acreage of 9,775 sq km. A 6,164 sq km 3D seismic survey across the three blocks was completed in the first half of 2009 to delineate high potential prospects identified on existing 2D seismic data. Tullow is in the process of increasing its equity position from 25% to 47.62% in Blocks LB-16 and LB-17 where reprocessing of the extensive 3D seismic dataset was undertaken in the second half of 2012. Tullow retains a 25% equity interest in Block LB-15.
To date, one exploration well has been drilled, Montserrado-1, which made an uncommercial oil discovery. Whilst the Liberia and Sierra Leone exploration campaign has had mixed results so far, the presence of oil shows together with thick reservoirs, albeit with oil pay in thinner reservoirs, remains encouraging for the overall exploration programme in the West African Equatorial Atlantic.
