Tullow Oil discovers more oil, gas in Kenya’s Block 10BB

Tullow Oil has announced that the Amosing-6 and Ngamia-10 appraisal wells in Block 10BB have now been successfully drilled encountering oil and gas in both wells. The Amosing-6 was drilled near the basin bounding fault and encountered 35 metres of net gas and oil pay and Ngamia-10 was drilled in an untested fault compartment and encountered 65 metres of net oil pay.

The operator now says data from these appraisal wells will be incorporated into the ongoing field development planning activities.

Following the completion of the Ngamia-10 well, the rig has been moved to the previously drilled Etom-2 well to prepare the well for a Drill Stem Test before proceeding to drill the fourth well of this campaign, the Emekuya exploration well, which will target the north-eastern flank of the Etom Complex. This well is likely to spud in early May.

EmekuyaThe Joint Venture partners have decided to extend the current exploration and appraisal campaign by a further three wells as earlier reported by OilNews Kenya. According to the explorer the additional wells will explore further the Greater Etom complex, test an undrilled fault block adjacent to the Ekales field and drill the Ngamia-11 well which will be used for an extended water flood pilot test in conjunction with the Early Oil Pilot Scheme (EOPS).

Meanwhile water injection testing on the Amosing-2A, Amosing-3, and Ngamia-5 wells has been successfully concluded, achieving good water injection rates and proving the feasibility of water injection for the development of these fields. Tullow adds that this success has enabled the Ngamia-11 water flood pilot to be incorporated into the EOPS activities which, along with the dynamic data collected from previous tests, will be used to finalise reservoir characteristics for the Field Development Plan.

Tullow Oil plc is the operator with 50% interest while joint venture partners Africa Oil and Maersk Olie og Gas A/S hold 25 percent  interests each.
