Heritage Oil to Test Deeper Horizons in Kingfisher Well

Heritage Oil is preparing to production test deeper intervals in the Kingfisher-1A deviated exploration well in Block 3A, Uganda. The Company is planning to test three intervals with a total thickness of 44 meters between 2,260 and 2,367 meters.

A shallower interval, at a depth of 1,783 meters, was tested successfully in the Kingfisher-1 well in November 2006, producing 4,120 bopd over a 10 meter interval. The tested oil was light (c. 30 degrees API) and sweet with a low gas-oil ratio and some associated wax. Flow data from the test indicated the reservoir had an extremely high permeability of over 2,000 milliDarcies.

Kingfisher-1A was drilled to a total depth of 3,195 meters, which was determined to be close to the limit of the rig's operational capability. Wire-line logs and formation pressure testing have evidenced encouraging indications of hydrocarbons over the planned test intervals, the thickest of which is 21 meters.

Heritage currently anticipates that it will commence testing within 10 days. The test program is scheduled to take up to three weeks. Test equipment has remained at the wellsite following the initial successful test of the Kingfisher-1 well.

Further details about Heritage's exploration activities in Uganda, including acquiring a 3D seismic survey and further appraisal drilling to evaluate the deepest potential of the basin will be announced when the results of the test program are available.

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