Heritage Oil Commences Drilling the Miran West-3 Well in the Kurdistan Region of Iraq

LONDON, UNITED KINGDOM--(Marketwire - Aug. 8, 2011) -

THIS PRESS RELEASE IS NOT FOR DISTRIBUTION TO UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES.

Heritage Oil Plc (TSX:HOC)(LSE:HOIL), an independent upstream exploration and production company, announces that it has commenced drilling the Miran West-3 well in the Kurdistan Region of Iraq ("Kurdistan").

Highlights

  • The Miran West-3 well has commenced drilling with the primary objective of appraising the Miran West structure
  • The well is targeting both the Jurassic and Cretaceous reservoir formations encountered in the Miran West-1 and Miran West-2 discovery wells
  • The deviated well path, determined from the recent 3D seismic survey, targets the flanks of the structure to optimally intercept networks of open fractures
  • It is intended that multiple reservoir intervals will be tested and evaluated as the well is drilled to a target depth of c. 4,400 metres
  • The well is expected to take approximately seven months to drill and test
  • The commencement of drilling of the Miran West-3 well represents the beginning of a multi-well appraisal and exploration programme, using the first of two rigs scheduled for back to back drilling on the Miran Field

Miran West-3 Well

Drilling of the Miran West-3 appraisal well has commenced. The well is targeting reservoir sections encountered in discovery wells with the primary objective of appraising the Jurassic and Cretaceous reservoir formations in the Miran West structure. 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.

The Miran West-3 location and well trajectory provides a c. 4.3 kilometre appraisal step out from the Miran West-2 Jurassic reservoir penetration. The planned well path targets the flanks of the structure. The well bore will be orientated and inclined to optimally intercept open fracture networks associated with multiple faults identified on recently acquired 3D seismic data. This well will also appraise the Cretaceous oil and gas reservoirs discovered in the Miran West-1 and Miran West-2 wells, further enhancing knowledge of the Miran structures.

Drilling of the Miran West-3 well is expected to take approximately seven months with key reservoir intervals being tested as the well is drilled.

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.

3D Seismic Programme

The Miran 3D seismic programme is now approximately 90% complete. The significant improvement in seismic data quality over the Miran Field is encouraging and assists greatly with the selection of well locations. Initial interpretation of the first tranche of data acquired has highlighted increased resource potential, in particular for the Miran East structure. This potential will be targeted by the Miran East-1 exploration well to be drilled before year end.

Tony Buckingham, Chief Executive Officer, 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."

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.
