Heritage Oil, the operator of the Kingfisher-2 exploratory appraisal well in Block 3A, Uganda, in which Tullow Oil plc (Tullow) is a 50%partner, today issued the following press release. Kingfisher-2, Block 3A, Uganda, Test Results Three reservoirs with a cumulative vertical net pay of approximately 37 metres between 2,654 metres and 2,783 metres measured depth produced at a cumulative flow rate of 14,364 bopd. The higher rates recorded from all three test intervals were constrained by the surface test equipment. It appears that these three zones are equivalent to the same three intervals tested in the Kingfisher-1 well, which flowed at a combined rate of 9,773 bopd. Pressure data recorded from the DST-1 and DST-2 intervals indicate that the two lowermost sands are possibly in vertical communication and therefore could comprise the same reservoir. This could potentially lead to higher oil volumes. The oil is good quality, of light to medium gravity and sweet, with a low gas-oil ratio and some associated wax.
