Tullow announced that the Nsoga-5 appraisal well, which is located in the Butiaba region of Uganda Block 2, has successfully encountered 10 meters of net oil pay. The Nsoga-5 appraisal well was drilled to a total depth of 587 meters, 2.3 km to the north-east of the Nsoga-1 discovery well, targeting equivalent reservoirs in a previously un-drilled fault block.

The successful Nsoga-5 well was the first of a multi-well appraisal program planned to further evaluate the extent and production potential of oil accumulations in the greater Nsoga area. The well has now been suspended for future re-entry.

The OGEC IRI-750 rig will now move 2 km south to the Kigogole field where it will drill the Kigogole-5 appraisal well.

Tullow has interests in three licenses in the Lake Albert Rift Basin in Uganda. Tullow operates Block 2 with a 100% interest and has a 50% interest in Blocks 1 and 3A which are operated by Heritage Oil (50%).

Commenting today, Angus McCoss, Exploration Director, said, "Another successful well in the Butiaba appraisal campaign further enhances our understanding of these high quality stacked fluvial reservoirs and will assist with the basin-wide development plan that Tullow and its new partners will be working on during the second half of 2010."
