Tullow Oil hits water-bearing reservoirs in Ethiopia
OIL/GAS exploration firm Tullow Oil has found water-bearing reservoirs in its South Omo block, onshore Ethiopia.
Tullow operates the South Omo block with a 50pc equity interest - Africa Oil has a 30pc stake and Marathon Oil another 20pc stake.
"The frontier wildcat well encountered lacustrine and volcanic rocks including almost 100 metres of net sandstone reservoir within siltstones and claystones," Tullow said in a statement.
Trace thermogenic gas shows were recorded at 1,900 metres, it added.
Angus McCoss, Exploration Director, Tullow Oil, 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."
