Irish explorer Tullow Oil is hoping to increase its African reserves estimates following mixed drilling results from its partly-owned blocks in Northern Kenya.
As reported by Tullow’s development partner Africa Oil, the initial Twiga-2 wellbore in block 13T found 18 metres of net oil reserves of limited quality.
But a subsequent sidetrack well encountered 62 metres of vertical net oil pay nearby the original Twiga-1 discovery.
Additionally, the Ekunyuk-1 well in block 10BB has encountered some five metres of net oil pay and an equal thickness of rich oil shale after being drilled to a total depth of 1,802 metres.
” 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,” said Angus McCoss, exploration director at Tullow Oil.
“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.”
