Tullow encounters Oil in Kenyan Block

Tullow Oil plc (Tullow) announces that the Etom-2 well in Block 13T, Northern Kenya, has encountered 102 metres of net oil pay in two columns. The objective of the well was to explore the Etom structure in an untested fault block identified by recent 3D seismic. Oil samples, sidewall cores and wire line logging all indicate the presence of high API oil in the best quality reservoir encountered in the South Lokichar Basin to date. Additional prospectivity identified on the 3D seismic in the north of the basin, including the Erut and Elim prospects, will now be considered as part of the future exploration drilling programme.

The PR Marriott Rig-46 drilled the Etom-2 well to a final depth of 1,655 metres and will now move to Block 12A where it will spud the Cheptuket-1 well around year end, the first well to be drilled in the Kerio Valley Basin. In Block 10BB, Tullow has completed the Ngamia Extended Well Test with approximately 38,000 barrels of oil produced. The five completed zones of Ngamia-8 were tested at a cumulative rate of 2,400 bopd and all except the lowest zone produced naturally. Communication between the producer well and an observation well at a distance of approximately 500 metres was also demonstrated. Tullow operates Blocks 13T and 10BB with 50% equity and is partnered by Africa Oil Corporation, also with 50%. For more information, please visit:
