Drilling operations were conducted on the Kigogole-1 well, which is located 1.5km from the crest of the structure. The well was drilled to a total depth of 616m and encountered two oil zones with a net pay of 10m. Logging, downhole pressure testing and sampling has confirmed the presence of moveable light sweet oil in reservoirs just below 400m.
Kigogle-1, drilled 10km north-east of the Kasamene-1 discovery, was the third test on the Victoria Nile delta play within the Lake Albert Rift Basin. Well results have confirmed the presence of quality reservoir and seals in this area, and upgraded several other adjacent prospects which will be tested during the 2009 Butiaba drilling campaign.
The Kigogole-1 well is now being suspended as a potential future production well and on completion of operations the rig will move to Block-1 to commence a three-well exploration drilling program. The first well in this program will be a test of the Warthog prospect which lies adjacent to the Kasamene-1 discovery.
Aidan Heavey, CEO of Tullow Oil, said: Kigogole is the fifth successive discovery in the Butiaba region within the last five months. This discovery reinforces the high potential of this area and in particular the Victoria Nile delta play.
