Tullow Oil and Africa Oil added to their Kenyan bounty with the drilling of the Etom-2 well on Block 13T in northern Kenya. The well encountered 102 meters 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 meters 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 bpd and all except the lowest zone produced naturally. Communication between the producer well and an observation well at a distance of approximately 500 meters was also demonstrated.
Analysts seem to be highly upbeat on Tullow’s prospects with this new discovery, as the company has deemed the Etom-2’s oil columns “the best quality reservoir encountered in the basin to date.” The well was testing an undrilled fault block in the northern flank of the basin and looks to have opened up a new play fairway. While reserves in Kenya have not been updated, the upside potential could put them up from 600 million barrels to about a billion barrels or more, especially with the additional prospects of the Elim and Erut.
