Tullow Oil has announced the successful drilling of the Nsoga-5 appraisal well, which is located in the Butiaba region of Uganda Block 2 in Uganda’s Albertine Graben region where huge oil deposits have been confirmed.

According to a statement from Tullow, the Nsoga-5 appraisal well was drilled to a total depth of 587 metres, 2.3 km to the north-east of the Nsoga-1 discovery well, targeting equivalent reservoirs in a previously un-drilled fault block.
Tullow says the Nsonga-5 well has successfully encountered 10 metres of net oil pay, meaning it is confirmed as commercially viable for oil production.
“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,” Angus McCoss, Exploration Director said today.
The successful Nsoga-5 well was the first of a multi-well appraisal programme planned to further evaluate the extent and production potential of oil accumulations in the greater Nsoga area.
The statement adds that 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%), although Tullow is set to buy out Heritage Oil’s interest.
