Heritage Oil, an independent upstream exploration and production company, has today announced that it has commenced drilling the Miran West-3 well in the Kurdistan Region of Iraq.
The primary objective at this stage is to appraise the structure of the well in the Jurassic and Cretaceous reservoir formations encountered in the Miran West-1 and Miran West-2 discovery.
Heritage currently intends to test and evaluate multiple reservoir intervals and as the well is drilled to a target depth of c. 4,400 metres, a process that Hertitage estimates will take seven months.
Heritage Energy Middle East, a wholly-owned subsidiary of Heritage, is operator and holds a 75% interest in the Miran Block and Genel Energy International Limited the remaining 25%, although there are third party back-in rights.
The Miran Block has an area of 1,015 square kilometres and is located west of the city of Suleimaniah. The Miran Block contains two large structures, Miran West and Miran East, which have been mapped from 2D and 3D seismic programmes conducted by Heritage.
Management estimates gross in-place volumes for the Miran West structure to have a P90-P50 range of 6.8-9.1 TCF of gas, with an upside P10 gas potential of 12.3 TCF. This is in addition to the estimated P50-P90 range of 42-71 MMbbls of condensate and 53-75 MMbbls of oil.
After drilling and testing, it is intended that this rig will move to drill the Miran West-4 appraisal well. A second rig is being sourced to drill the planned Miran East-1 exploration well, with drilling expected to commence before year end, at which time there will be two rigs operating in the Miran Field.
Meanwhile, Heritage’s Miran 3D seismic programme is now approximately 90% complete.
The company estimates that the Miran East-1 exploration well will be drilled before year end.
Tony Buckingham, Hertage Oil CEO, commented: “The spudding of Miran West-3 begins our active multi-well exploration and appraisal drilling programme in Kurdistan. This first well is principally appraising the Cretaceous and Jurassic discoveries made in the Miran West-1 and Miran West-2 wells. We plan to provide regular announcements during the drilling of this well as the key reservoir intervals will be tested as the well is drilled.”
