Precision Drilling Corporation

A Calgary-based contractor that drills onshore wells for oil, natural gas, and geothermal energy companies across North America. Founded in 1951 with a single rig, the company chose the name "Precision" to signal its commitment to technical accuracy. In the 1960s it pioneered the "Deep Freeze-Hole" technique to sink shafts through waterlogged potash formations in Saskatchewan.
