Tullow Successfully Tests Third Appraisal Well at Kaiso-Tonya

The third and final well being drilled for the Kaiso-Tonya appraisal program has proved successful for Tullow Oil. The Mputa 4 appraisal well is located in Uganda’s Block 2 and has established the lateral extent of oil-bearing reservoirs in the area.

“The program, which was completed on time and within budget, has improved our understanding of the ultimate reserve potential of this onshore region, and will be further enhanced over the coming months by the results from the ongoing 3D seismic acquisition,” said Tullow’s Chief Executive Aidan Heavey in a released statement.

Located one kilometer east of the Mputa 1 discovery well, Mputa 4 was drilled to test an adjacent fault block. At a total depth of 1,073 meters, the well detected three oil-bearing zones with a total net pay of 15.4 meters. Similar to the other Mputa wells, downhole pressure testing and sampling of the Mputa 4 indicate moveable light sweet crude with very good permeabilities.

The Kaiso-Tonya appraisal program will help to establish the reserve potential for the area. 3D seismic studies continue for the three wells, with the potential of additional production testing.

A European exploration company, Tullow Oil holds interest in 120 exploration and production licenses in 24 countries worldwide. On the Ugandan portion of the Albert Rift Basin, Tullow operates 100 percent interest in Uganda’s Block 2, in addition to holding 50 percent interest in both Blocks 1 and 3A.
