Tullow Oil plc (Tullow) announced that the Emekuya-1 well in Block 13T, Northern Kenya has encountered around 75 metres of net oil pay in two zones.
Emekuya-1 is located 2.5 km north of Etom-2 and had the objective of drilling a fault block on the flank of the Greater Etom structure. The well was drilled by the PR Marriott Rig-46 to a total measured depth of 1,356 metres and penetrated reservoir quality Miocene sandstones which correlate to those seen in the successful Etom-2 well.
Downhole pressure measurements and fluid samples suggest that the main oil reservoir is on the same static pressure gradient as the Etom-2 well which demonstrates that a major part of the Greater Etom structure is oil-filled. The reservoir sands encountered also appear to be extensive which further de-risks the northern play area and bodes well for future exploration in the region.
The rig will be moved to drill an up-dip appraisal well on the Greater Etom structure. Tullow operates Blocks 13T and 10BB with 50% equity and is partnered by Africa Oil Corporation and Maersk Oil both with 25%.
