Tullow Oil PLC said an exploratory well drilled in the South Lokichar basin in northern Kenya encountered 102 m of net oil pay in two columns.
The Etom-2 well, on Block 13T, was drilled to 1,655 m by the PR Marriott Rig-46 (OGJ Online, Nov. 17, 2015). Drilling followed evaluation of 3D seismic that was shot after the Etom-1 well (OGJ Online, Sept. 3, 2014).
Tullow said oil samples, sidewall cores, and wireline logging all indicate the presence of high API oil in the best quality reservoir encountered in the South Lokichar basin.
Tullow operates Blocks 13T and 10BB and has 50% interest. Africa Oil Corp. has 50%.
In Block 10BB, Tullow said it has completed the Ngamia extended well test, producing 38,000 bbl. Five completed zones of Ngamia-8 were tested at a cumulative rate of 2,400 b/d. All except the lowest zone produced naturally.
Tullow said the Marriott rig will move to Block 12A to spud the Cheptuket-1 well in the Kerio Valley basin.
