Jupiter-1 discovery offshore Sierra Leone

Tullow Oil plc (Tullow) announces that the Jupiter-1 exploration well in Block SL-07B-11 offshore Sierra Leone has successfully encountered hydrocarbons. This has been confirmed by the results of drilling, wireline logs and samples of reservoir fluids. The well, located over 25 kilometres west of the Mercury-1 well which discovered oil in the block, intersected 30 metres of hydrocarbon pay in the primary Upper Cretaceousobjective and did not encounter a hydrocarbon water contact. The well has been preserved for possible future re-entry, as the area is likely to require additional evaluation. Jupiter-1 was drilled by the Transocean Discoverer Spirit drillship to a total depth of 6,465 metres in a water depth of 2,199 metres. On completion of operations, the drillship will move 15km northeast to the Mercury-2 well which will target several reservoir levels including extensions of the oil accumulations discovered by the Mercury-1 well. Anadarko (55%) is Operator of offshore Block SL-07B-11 along with partners Repsol (25%) and Tullow (20%).

Montserrado-1 makes a non-commercial oil discovery

Tullow Oil plc (Tullow) announces that the Montserrado-1 exploration well, offshore Liberia, has made a non-commercial oil discovery in Late Cretaceous reservoir sands. This result is an important exploration breakthrough, establishing a working hydrocarbon system in the Liberian basin. The well was drilled in block LB-15 to a total depth of 5,400 metres and encountered good-quality, water-bearing sands in the main objective. In a deeper secondary objective, approximately 8 metres of hydrocarbon pay was intersected and a sample of light oil was recovered. The well is being plugged and abandoned and the drillship is being mobilised to Sierra Leone to drill the Mercury-2 appraisal well and the Jupiter exploration well on block SL-07B-11. Tullow has a 25.00% working interest in the licence and is partnered by the operator, Anadarko Petroleum (47.5%) and Repsol (27.5%).
