Contract Drilling - Canada

Ensign Energy Service's operates our Canadian drilling rig fleet, the second largest in Canada, through the Ensign Drilling Partnership, which comprises five business divisions: Big Sky Drilling, Champion Drilling, Encore Coring & Drilling, Ensign Drilling and Tri-City Drilling.

Ensign's Canadian drilling rig fleet offers customers both quality and flexibility, and encompasses the complete spectrum of oil and natural gas drilling depths - from approximately 400 metres (1,300 feet) to more than 6,000 metres (20,000 feet). The mobility characteristics of a drilling contractor's fleet are critical to its competitive nature. Ensign's rig fleet meets the highest standards for mobility. In addition, Ensign's Canadian drilling rig fleet is configured to accommodate the requirements of the latest drilling technology and processes, such as horizontal and underbalanced drilling technology, slant drilling, and the horizontal re-entry of existing wells.
