May 23, 2014 – Irish-owned prospector, Tullow Oil, this morning said that its Shimela-1 well in Ethiopia has encountered water bearing reservoirs and only traces of gas 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, it said.
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 50pc equity and is partnered by Africa Oil Corporation and Marathon Oil Ethiopia, a wholly owned subsidiary of Marathon Oil Corporation.
