Tullow plugs and abandons dry onshore Ethiopia wildcat

14th July 2014

Tullow Oil has announced that the Gardim-1 exploration well, drilled on the eastern flank of the Chew Bahir Basin in the South Omo licence, onshore Ethiopia, has reached a total depth of 2,468 metres in basement, without encountering commercial oil

The well will be plugged and abandoned and drilling operations will now be demobilised whilst these results are integrated into the regional basin model

The well intersected lacustrine and volcanic formations, similar to those found in the Shimela-1 well on the north-western flank of the basin.

“We have now drilled two independent wildcat wells in the Chew Bahir Basin, neither of which encountered commercial oil,” said Angus McCoss, exploration eirector, Tullow Oil. “Whilst 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.”

Minor intervals with thermogenic gas shows were intersected just above basement.

The well will be plugged and abandoned and drilling operations will now be demobilised whilst these results are integrated into the regional basin model.

Meanwhile seismic interpretation continues on independent prospectivity elsewhere in the licence and the next phase of our Ethiopia exploration campaign will target these prospects.
