HOUSTON, Nov. 7 -- Heritage Oil Corp., London, has completed two drillstem tests of the upper zone of the Kingfisher-1 well on Block 3A in Uganda.
The first test did not flow hydrocarbons to surface. However, the second tested two zones totaling 10 m over the interval from 1,783 m to 1,795 m, which flowed at a stabilized rate of 4,120 b/d of oil through a fixed 1-in. choke at a flowing wellhead pressure of 221 psi. The oil was light (30° gravity) and sweet with a low gas-oil ratio and some associated wax.
The test flow data suggest that when equipped for production, the well could flow at stable rates of about 5,600 b/d. They also indicated permeability of more than 2,000 md.
The tests represented a secondary exploration objective for the well, which will be sidetracked. Drilling will now continue to the deeper primary objectives. It is expected to take a further 45-60 days to reach TD of 3,000-4,000 m. Test equipment will remain on location to test the primary target (OGJ Online, Oct. 16, 2006, Newsletter).
