Heritage Oil to Production Test Kingfisher-1 in Uganda

Heritage Oil is preparing to production test the Kingfisher-1 exploration well in Block 3A, Uganda. The Company is planning to test up to four intervals with a total net pay of 37 meters in a stacked sand and shale sequence that is typical of the basin. In order to do so, drilling operations have been temporarily suspended.

The well has been drilled to a depth of 2,125 meters, and wireline logs and formation pressure testing and sampling have evidenced encouraging indications of hydrocarbons. Heritage anticipates that it will commence testing of the Kingfisher-1 well within a month and the testing program is scheduled to take up to three weeks.

The well encountered hydrocarbons within a section above the primary objective. Drilling to the primary objective is planned to recommence after this initial well testing operation has been completed. It is estimated that it could take a further 60 days to reach target depth of between 3,000 and 4,000 meters.

Further details about Heritage's exploration activities in Uganda will be announced when the results of the initial test program are available.

Heritage is the Operator of Block 3A in Uganda with a 50% equity in the license, with Tullow Oil holding the remaining 50% interest.
