Tullow Oil said the Shimela-1 well, onshore Ethiopia, has encountered water bearing reservoirs and only traces of thermogenic gas shows were recorded after drilling to a final depth of 1,940 metres. The rig will now be moved to drill the Gardim-1 wildcat exploration well in a completely separate sub-basin, in the south-eastern corner of the Chew Bahir basin.Angus McCoss, Tullow's Exploration Director, said: "Although the Shimela well only found traces of thermogenic gas, it has provided key data to continue to build our understanding of the north-western part of the Chew Bahir basin. "The prospectivity at the Gardim-1 well, which is targeting an independent petroleum system in a separate south-eastern sub-basin, is not affected by this result."Tullow Operates the South Omo Block where Shimela-1 is located with 50% equity and is partnered by Africa Oil Corporation and Marathon Oil Ethiopia, a wholly owned subsidiary of Marathon Oil Corporation.NR
