ANOTHER huge oil well has been discovered in the Butiaba region on Lake Albert, Tullow Oil, a UK exploration group, said on Tuesday.
The firm, which is exploring oil and gas in western Uganda, said the well was “one of the largest recent onshore oil discoveries in Africa.â€
“Buffalo-Giraffe is one of the largest recent onshore oil discoveries in Africa,†Aidan Heavy, the Tullow chief executive officer, said in a statement.
“Combined with our other finds in the region, we have now clearly exceeded the thresholds for basin development.â€
Aidan added that options for commercialisation and first oil production were being fast-tracked.
The Giraffe-1 exploration well, which is located in the Butiaba region of Uganda Block 1, has over 38 metres of net oil pay within an 89 metre gross oil bearing interval.
These results demonstrate Giraffe to be a down-dip extension of the Buffalo discovery, making this the largest discovery in the Lake Albert Rift Basin to date.
The well was drilled 5km from Buffalo-1 to a total depth of 705 metres and has been successfully logged and sampled.
These data indicate a net reservoir thickness of 38 metres, the largest encountered in the area to date, with excellent reservoir quality in all pay zones with moveable oil being recovered to surface.
Interpretation of the well and seismic data indicates that the reservoir sands intersected in the Giraffe-1 well are in communication with those in the Buffalo discovery.
An oil-water contact was penetrated and is interpreted as being common to the entire Buffalo-Giraffe structure with the potential for a single continuous oil column of some 140 metres.
Giraffe-1 is the sixth successful test of the Victoria Nile delta play fairway within the Lake Albert Rift Basin and was drilled some 6.5 km south of the crest of the Buffalo-Giraffe structure.
This latest result further extends the play fairway and de-risks several adjacent prospects, located in Blocks 1 and 2, which are scheduled for drilling in 2009.
The well will now be suspended as a future producer and on completion of operations the light land rig will move to the Tullow Operated Block 2. Drilling operations will recommence in early February with the drilling of the Mputa-5 appraisal well to calibrate recently enhanced seismic data. Thereafter the rig will return to the Block 2 Butiaba campaign.
Tullow has interests in three licences in the Lake Albert Rift Basin in Uganda. Tullow operates Block 2 with a 100% interest and has a 50% interest in Blocks 1 and 3A which are operated by Heritage Oil (50%).
