Heritage Oil PLC said a production test indicates that future development wells on the Miran West structure in Iraqi Kurdistan could produce at rates of 8,000-10,000 b/d/well of 15° gravity oil from the Upper Cretaceous reservoir at 876 m.
The Miran West-3 well tested at the maximum rate of 1,950 b/d of oil, limited by surface equipment, with little associated gas. Heritage said the test confirms its estimate of gross in place contingent volumes of 53-75 million bbl of oil in Upper Cretaceous at Miran West.
Drilling resumed on prognosis to test the deeper reservoirs discovered by earlier drilling. Heritage said, “Drilling of this well is demonstrating the ability to intersect the productive fracture network associated with multiple faults identified on recently acquired 3D seismic data. We are drilling ahead with a view to conducting the next test in the Lower Cretaceous reservoir.”
Interests in the 1,015 sq km Miran block are Heritage 75% and Genel Energy International Ltd. 25%, although there are third party back-in rights.
