Heritage Oil has announced a major gas discovery at the Miran West-2 well in the Kurdistan Region of Iraq, following completion of its deepening and testing phase.
Heritage estimates that the Miran West structure has P90-P50 gross in-place volumes of 6.8-9.1 trillion cubic feet of gas, with 42-71 million barrels of condensate and 53-75 million barrels of oil.
The Miran West-2 well was initially designed as an appraisal well for the Cretaceous section and was modified later to assess the exploration potential of the deeper formations, which were drilled to a total depth of 4,426m.
The well results have confirmed three additional pay zones within the Lower Cretaceous and Jurassic formations, in addition to the pay zone identified in the Upper Cretaceous area of the Miran West-1 well.
