Tullow success in Block 2 Uganda

Tullow Oil plc (Tullow), a leading independent oil & gas, exploration and production group, announces further success in Uganda’s Lake Albert Rift Basin with the Ngege-1 exploration well encountering both oil and gas.

The well is the second in a continuous exploration campaign in the Butiaba region of Blocks 1 and 2.

Ngege-1 encountered over five metres of net oil pay and nine metres of net gas pay in separate sands and was drilled to a total depth of 640 metres.

The well was drilled some three kilometres from the crest of the structure and seismic interpretation indicates further significant potential updip.

Downhole pressure testing and sampling have confirmed the presence of dry gas and moveable 30-32˚ API oil. Reservoir quality for both zones is excellent. Logging has been successfully completed and the well has been suspended as a potential future producer.

Ngege-1 is located 41 kilometres north-east of the Taitai-1 discovery well and tested the Victoria Nile Delta play in a new fairway along the axis of the Lake Albert Rift Basin.

Results have confirmed the presence of well developed reservoir and seals, and thereby upgrade several other prospects which are included in the current drilling campaign.
