Uganda's Kasamene yields thick pay interval

Tullow Oil PLC said its Kasamene-2 appraisal well in Uganda Block 2 encountered 39 m of net oil pay and 8 m of net gas pay in a 132-m gross interval, the thickest net pay yet found in the Butiaba area of Block 2 in the Lake Albert rift basin.

-- Tullow Oil PLC said its Kasamene-2 appraisal well in Uganda Block 2 encountered 39 m of net oil pay and 8 m of net gas pay in a 132-m gross interval, the thickest net pay yet found in the Butiaba area of Block 2 in the Lake Albert rift basin.

Well and seismic data indicate the reservoir sands are in pressure communication with those at Kasamene-1, which flowed more than 3,500 b/d of oil in March 2009 (see map, OGJ, Feb. 16, 2009, p. 34). Kasamene-2, TD 866 m, is near the field’s crest and 1 km northeast of Kasamene-1.

Kasamene-2 pressure data confirmed a single continuous oil column in excess of 70 m and a gas column of over 20 m. The well is to be suspended as a future producer as part of Phase 1 of the Albertine rift development, Tullow said.

Kasamene-2 is the first of two Kasamene appraisal wells being drilled to support the field’s proposed development. Four more appraisal wells will be drilled in 2010 to delineate the other significant discoveries in this area.

Tullow operates Block 2 with 100% interest and has 50% interest in Blocks 1 and 3A operated by Heritage Oil Corp., Calgary.
