Heritage Oil announced Thursday that drilling of the Miran East-1 exploration well in the Kurdistan region of Iraq has commenced with an estimated target depth of approximately 13,120 feet (4,000 meters). This is the first well to be drilled on what the firm described as a highly prospective eastern structure, which has an area of approximately 50 square miles (130 square kilometers).
The well is targeting exploration potential within the Cretaceous and Jurassic reservoir intervals of the eastern structure, contiguous with the hydrocarbon bearing Miran West structure. The well design utilizes recently acquired 3D seismic data and the enhanced understanding of the structural configuration within the Miran Field that this has provided.
Drilling of Miran East-1 is expected to take approximately seven months with multiple intervals to be evaluated and tested as the well is drilled.
T"Our work program in Kurdistan continues with the spudding of the Miran East-1 exploration well. The large, undrilled Miran East structure has the potential to add significant hydrocarbon resources at all of the multiple reservoir intervals," said Heritage Chief Executive Officer Tony Buckingham.
Heritage Energy Middle East, a wholly-owned subsidiary of Heritage, is operator and holds a 75-percent interest in the Miran Block and Genel Energy the remaining 25 percent, although there are also third party back-in rights.
The Miran Block has an area of 390 square miles (1,015 square kilometers) 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 programs conducted by Heritage.
