The Cretaceous reservoir at Tawke field in the Kurdistan Region of Iraq is flowing at a record rate of 25,000 b/d of oil from the first horizontal well, said DNO International ASA, Oslo.
By comparison, the highest flowing vertical Tawke field well averages 10,000 b/d, the company said (OGJ Online, June 11, 2013).
The Tawke-20 horizontal well previously averaged of 8,000 b/d from each of the first four of 10 fractured corridors penetrated by a 600-m horizontal section in the Cretaceous reservoir. Each of the remaining six corridors also averaged of 8,000 b/d.
With tests complete, the well has been placed on production but is subject to wellbore and surface facilities limitations.
Bijan Mossavar-Rahmani, DNO International’s executive chairman, said, “Our next task is to optimize production from Tawke-20 while assessing the potential of horizontal wells in terms of drilling efficiency, well recovery factor and overall Tawke field output capacity.”
DNO International is drilling Tawke-23 preparing to spud Tawke-21, both horizontal wells.
DNO International holds a 55% interest in and operates the Tawke license. Genel Energy PLC has 25% and the Kurdistan Regional Government 20%.
