Tullow Oil recently announced the Etom-2 well in Block 13T, Northern Kenya, has encountered 102 m 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 possible reserves were identified on the 3D seismic in the north of the basin, including the Erut and Elim prospects, and will now be considered as part of the future exploration drilling program.
The PR Marriott Rig-46 drilled the Etom-2 well to a TD of 1,655 m and will now move to Block 12A where it will spud the Cheptuket-1 well around yearend – 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 bbl of oil produced. The five completed zones of Ngamia-8 were tested at a cumulative rate of 2,400 BPD, and all except the lowest zone produced naturally. Communication between the producer well and an observation well at a distance of approximately 500 m was also demonstrated.
Tullow operates Blocks 13T and 10BB with 50% equity and is partnered by Africa Oil Corporation with 50%.
