Tullow Oil has made an oil discovery in the Batlaba region of Uganda block 1.

Tullow’s Ngiri-2 appraisal well encountered over 40m of net oil-bearing reservoir in two zones within an overall 131m gross oil-bearing interval.

The well was drilled 1.7km north of the Ngiri-1 discovery well to a total depth of 892m.

The Ngiri-2 well is the first of a multi-well appraisal programme planned to further evaluate the extent and recovery potential of the Ngiri field.

Tullow said further activities will take place in Q4 2010 with the drilling of down-dip appraisal wells Ngiri-3 and Ngiri-4, which are designed to establish oil water contacts and reservoir distribution.

Tullow exploration director Angus McCoss said the company’s exploration and appraisal campaign in Uganda has now discovered over 950 million barrels of oil.

Tullow owns 100% interests in three licences – blocks 1, 2 and 3A – in the Lake Albert Rift Basin in Uganda.
