Tullow Oil has discovered oil at three of its exploration and appraisal wells at Blocks 10BB and 13T, onshore Kenya.
Located in the South Lokichar basin, the Etom-1 well in Block 13T encountered approximately ten metres of net oil pay with an extension of the proven oil basin northwards.
The company has extended the ongoing 550km² 3D seismic survey in the South Lokichar basin to cover an additional 247km² in this northern area, including various similar prospects that are due to be drilled in 2015.
The Amosing-2 well in Block 10BB encountered around 30m net oil pay.
Tullow said the well was deviated 1,350m towards the north-east and downdip from the discovery well to calibrate the oil-water contacts of various oil pools discovered in Amosing-1.
The well was sidetracked back to 400m from the discovery well to offer further insight into reservoir distribution in the area and for use in interference testing, planned to commence later in 2014.

By GlobalDataThe Amosing-2A sidetrack encountered around 90m net oil pay in various oil pools.
The Ngamia-3 well, also in Block 10BB, encountered 150m of net oil pay in both Auwerwer and Lokone reservoirs.
Tullow operates Blocks 10BB and 13T with 50% stake along with Africa Oil, which holds the remaining interest.
Tullow Oil exploration director Angus McCoss 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."
