Tullow encounters oil in Kenya well

LONDON -- Africa Oil, Tullow Oil’s partner in Blocks 10BB and 13T in Northern Kenya (Tullow 50% operated interest), issued the following operational updates in their quarterly results statement.

Twiga-2 sidetrack encounters 62 m of net oil pay

“The Sakson PR5 rig is continuing drilling operations on the Twiga-2 up-dip appraisal well.  The initial wellbore was drilled near the basin bounding fault and encountered some 18 m of net oil pay within alluvial fan facies, with limited reservoir quality. A decision was therefore made to sidetrack the well away from the fault to explore north of Twiga-1 and some 62 m of vertical net oil pay has been discovered in the Auwerwer formation, similar in quality to the initial Twiga-1 discovery.  The well is currently being deepened to evaluate the Lower Lokhone potential and a testing program for this successful well is planned to be conducted later this year.”

Ekunyuk-1 finds best sands on eastern flank although lacks trap

“The Ekunyuk-1 well is located on the eastern flank, on trend with recent discoveries at Etuko and Ewoi. The well has now reached a final total depth of 1,802 m and has encountered some 5 m of net oil pay, within approximately 150 m of reservoir quality water-bearing sandstone and an equal thickness of a basin-wide rich oil shale. This rig will now be moved to the Agete-2 location.”

Angus McCoss, Exploration Director, Tullow Oil, commented : “I am pleased to announce that the Twiga-2 exploratory sidetrack has encountered material oil-bearing sandstone reservoirs north of Twiga-1. The combined results from Twiga-2 and its successful sidetrack confirm the resource potential and have given us valuable insights for the locations of future exploration and development wells. The Ekunyuk-1 well encountered the best developed reservoir sands so far on the east flank, although at this location the trap appears to be incompletely formed. Additionally, the presence of a thick extensive oil shale gives us new options to study the basin’s substantial unconventional oil potential.”
