Director of the National Iranian Drilling Company Heidar Bahmani announced on Thursday that oil well perforations via percussion drilling were successfully conducted at an oil well near Iran's western city of Dehloran.
The cited method has been exclusively practiced by North America and certain European countries up until now, IRIB quoted the official as saying.
The method applies focused pressure through special 'perforator guns' to penetrate layers of the ground in order to dig both modern 'deflected' and older horizontal wells.
Through this method, the heavy cost of oil well casing will be reduced and the excavation sites' safety will improve.
The casing of oil wells is a supplementary procedure in drilling operations which helps boost the well's half-life.
