Tullow reported that the Kasamene-3 and Kasamene-3A wells in the Butiaba region of Uganda Block 2 have successfully delineated the extent of oil in the Kasamene field and discovered oil in the Wahrindi North fault block.

The Kasamene-3 well was drilled down-dip and 2.2 kilometers to the southwest of the Kasamene-1 discovery well. This deviated well was drilled to a total depth of 1,109 meters and results of logging confirmed some 10 meters of oil pay within a 35 meter thick reservoir section of the Kasamene field. Pressure data confirmed this pay to be in communication with the up-dip Kasamene-1 well, successfully extending the column height of these reservoirs to over 100 meters. High quality reservoirs, 25 meters thick, were encountered on prognosis below the oil-water contact. This successful outcome proves the viability of this location as a future water injection point to support up-dip oil production.

A second well, to explore the Wahrindi North fault block, was then drilled utilizing the top-hole section of Kasamene-3. This well, Kasamene-3A, was drilled to a total depth of 988 meters into a separate fault compartment 300 meters to the southwest and encountered over 15 meters of oil pay.

The rig will now move to the Kaiso-Tonya area to drill the Nzizi-3 appraisal well in support of the accelerated Nzizi gas development project.

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%).
