The Gardim-1 well drilled on the South Omo license in Ethiopia by Tullow Oil failed to find commercial reserves. Tullow said the well was drilled to a total depth of 2,468 meters in basement, without encountering commercial oil. The well intersected lacustrine and volcanic formations, similar to those found in the Shimela-1 well on the north-western flank of the basin. Minor intervals with thermogenic gas shows were intersected just above basement.
The well will be plugged and abandoned and drilling operations will now be demobilized while these results are integrated into the regional basin model. Meanwhile seismic interpretation continues on independent prospectivity elsewhere in the license and the next phase of the Ethiopia exploration campaign will target these prospects.
Angus McCoss, Exploration Director, Tullow Oil plc commented: “We have now drilled two independent wildcat wells in the Chew Bahir Basin, neither of which encountered commercial oil. While our analysis continues, initial indications suggest that the targeted seismic anomalies related to lavas that flowed into a lake basin. Having gained valuable data, including evidence of thermogenic gas, we look forward to the next phase of our exploration campaign in Ethiopia.”
