Tullow Oil says that the Etom-1 well in Block 13T is the most northerly well drilled to date in the South Lokichar basin, 6.5 km north of the previous Agete-1 discovery. The well encountered approximately 10 metres of net oil pay, extending the proven oil basin significantly northwards. Based on this result the ongoing 550 sq km 3D seismic survey in the South Lokichar basin has been extended to cover a further 247sq km in this northern area, including several similar prospects which are scheduled to be drilled in 2015.

The Weatherford 804 rig drilled the Etom-1 well to a final depth of 2,000 metres. The well will be suspended for use in future appraisal and development operations, following which the rig will move to drill the Kodos-1 well in September 2014 to test the first of several prospects identified in the neighbouring Kerio Basin.
