UK-based oil independent Tullow Oil has hit oil at the Kigogole-3 exploration well, located in the Butiaba region, offshore Uganda.

The well, in Uganda block 2, has encountered more than 20m of net oil pay in two separate zones. Located about 1km from the crest of the structure, the well was drilled to a total depth of 575m and has been successfully logged and sampled.

The company said that Kasamene-type reservoir sands were encountered in the lower zone with more than 15m of net oil pay.

In a separate 5m total net reservoir section above the 15m main reservoir interval, thin-bedded oil bearing sands were also encountered, Tullow said.

Kigogole-3 is the eighth successful test of the Victoria Nile Delta play fairway within the Lake Albert Rift basin. The well is located southwest of the Kigogole-1 oil discovery made in 2008, which was recently production tested. This latest result further extends the play and de-risks several adjacent prospects located in blocks 1 and 2, which are scheduled for drilling later in 2009.

The well is now being suspended as a future oil producer and on completion of operations the rig will move to the Wahrindi prospect, 13km to the south-west, close to the shore of Lake Albert. The well is expected to commence later this month and to drill to a depth of about 1,300m.
