Tullow Oil plc announces that the Taitai-1 exploration well, drilled in the Butiaba region of Uganda Block 2, has encountered five meters of net gas pay and at least eight meters of net oil pay. A thick section of oil-stained basement was also encountered and provides upside potential both at Taitai-1 and elsewhere in the Lake Albert Rift Basin.
The well was drilled to a total depth of 1,006 meters and has been successfully logged. Downhole pressure testing and sampling has confirmed the presence of moveable 30 degrees API oil and a potential oil column of up to 80 meters, in sands above the basement play.
The uppermost oil sand exhibited high permeability; however pressure sampling of underlying oil sands was inconclusive. This uncertainty provides upside beyond the eight meters net oil pay, consequently the well is being sidetracked and the oil bearing zones cored to collect further reservoir and fluid information for detailed analysis.
The Taitai-1 well is the first of a nine-well exploration campaign in the Butiaba area of the Lake Albert Rift Basin. On completion of operations at Taitai-1, the rig will move 10 kilometers to the north-east and drill the Lanya-1 prospect at the end of May. The best candidates for testing will be assessed on overall merit, at the end of the drilling campaign.
"The discovery of oil at Taitai has proved the existence of a working petroleum system over 70 kilometers from the previous wells drilled in the Kaiso-Tonya region and further reinforces the potential of Lake Albert Rift Basin as a major emerging petroleum province," Aidan Heavey, Chief Executive of Tullow said. "We are encouraged by the Taitai result and look forward to the remainder of the campaign in the Butiaba area"
