Tullow Updates Kenya Drilling

Friday, March 28, 2014

Tullow Oil issued the results of its recent drilling activities in Kenya on Blocks 10BB and 13T. The Emong-1 exploration well on Block 13T was drilled to test a structure directly across the main basin bounding fault. The well encountered poorly developed oil bearing reservoir sands at this location. The well was drilled using the Weatherford 804 rig to a final depth of 1,394 meters.

Following the completion of the Emong-1 well the rig will be moved to drill the Ekunyuk-1 wildcat on the eastern portion of Block 13T. This well will test the rift flank play where the Etuko and Ewoi discoveries were made.

The Sakson PR-5 rig is continuing drilling operations on the Twiga South-2 up-dip appraisal well which is expected to be completed in mid-April. This rig will then move to drill a down-dip appraisal of the Amosing discovery, which appears to have high quality reservoir and may be one of the largest discoveries in the basin to date.

Following the successful drill stem test of the Etuko-1well on Block 10BB the PR Marriott rig remained on location to drill the Etuko-2 well. This well was designed to evaluate a very shallow reservoir zone penetrated in the first Etuko well but which could not be properly logged due to the wide gauge of the original well. The rig drilled Etuko-2 well to a final depth of 650 meters and the well flowed water with oil shows. The rig will now move to drill the Ngamia-2 to appraise the Ngamia discovery.

The SMP-5 rig, contracted to conduct a series of drill stem tests on the discoveries in northern Kenya, conducted a drill stem test on the Ekales-1 oil discovery on Block 13T and successfully flowed over 1,000 bpd of oil. The rig will now move to conduct a drill stem test on the AGete-1 discovery on Block 13T.  

Angus McCoss, Exploration Director, Tullow Oil, commented: “The early exploration, appraisal and testing activities onshore Kenya are giving us significant technical and operational insights for further optimizing and accelerating the development of the basin. Our focus remains on continuing to explore and appraise our first successful basin, as well as stepping out into several untested basins, which together form a chain of prospective basins that have the potential to become a transformational new oil province.”
