Irish-owned global energy explorer, Tullow Oil, today said it was encouraged by successful results from a series of exploration, appraisal and testing activities conducted in Blocks 10BB and 13T onshore Kenya.
It said that 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 company said that the Amosing-2 well in Block 10BB is the first appraisal well on the Amosing field discovered in January 2014, and was drilled from the Amosing-1 well pad. The well was deviated 1,350 metres towards the northeast and downdip from the discovery well to calibrate the oil-water contacts of the several oil pools identified in Amosing-1. The Amosing-2 well encountered up to 30 metres net oil pay. As planned, the well was then sidetracked back to some 400 metres from the discovery well to provide additional insight into reservoir distribution in the area and for use in interference testing, planned to start later in 2014. The Amosing-2A sidetrack encountered up to 90 metres net oil pay in several oil pools.
Commenting today, Angus McCoss, Exploration Director, said: "Etom-1 has successfully extended the South Lokichar rift bounding fault play northwards and we look forward to testing the southern area of the basin with Ekosowan-1. Continued success in appraisal of the Ngamia and Amosing fields reinforces our belief that the South Lokichar basin holds very considerable potential which we hope to replicate in additional basins. The next basin-opening test will be in the neighbouring Kerio Basin, with the Kodos-1 well expected to spud in early September".
