Tullow finds oil at Kasamene field, Uganda

13th Apr 2010 07:25

Tullow Oil said the Kasamene-3 and Kasamene-3A wells in the Butiaba region of Uganda Block 2 have successfully delineated the extent of oil in the Kasamene field and discovered oil in the Wahrindi North fault block. The Kasamene-3 well was drilled down-dip and 2.2 kilometres to the southwest of the Kasamene-1 discovery well. This deviated well was drilled to a total depth of 1,109 metres and results of logging confirmed some 10 metres of oil pay within a 35 metre thick reservoir section of the Kasamene field. Pressure data confirmed this pay to be in communication with the up-dip Kasamene-1 well, successfully extending the column height of these reservoirs to over 100 metres. High quality reservoirs, 25 metres thick, were encountered on prognosis below the oil-water contact. This successful outcome proves the viability of this location as a future water injection point to support up-dip oil production, Tullow said. A second well, to explore the Wahrindi North fault block, was then drilled utilising the top-hole section of Kasamene-3. This well, Kasamene-3A, was drilled to a total depth of 988 metres into a separate fault compartment 300 metres to the southwest and encountered over 15 metres of oil pay.Exploration Director Angus McCoss said: "These Kasamene and Wahrindi North exploratory appraisal results have successfully delineated the upside potential in this immediate area. This takes us a significant step towards first oil in Uganda, which is expected from the Kasamene field in 2011." "We continue to work closely with the Government of Uganda on plans for accelerating our exploration and appraisal activities in the region and look forward to commencing a multi-well programme with a second rig in Block 1 next month."
