Tullow
Oil Makes Another Discovery on Lake Albert
06-25-2008
 Tullow Oil plc 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.
The Karuka-1 prospect, which lies 24 kilometres south of Ngege-1, is the next
drilling location and operations are expected to commence at the end of June.
Karuka-1 is an escarpment fan prospect analogous to the Taitai-1 discovery.
There are no plans to test Ngege-1 at this time, the best candidates for testing
and appraisal drilling will be assessed on overall merit at the end of the
regional drilling campaign.
Commenting today, Aidan Heavey, Chief Executive
of Tullow said:
“We are very pleased with the efficient progress we are making with the Butiaba
campaign in Uganda. This is the eleventh well in the basin to encounter
hydrocarbons and has extended the range over which oil has been discovered to
150 kilometres. With Ngege-1 opening up a new deltaic play fairway with high
quality reservoir we are very encouraged by the potential of this progamme in
the north of Block 2."
