Our Story

ENSIGN IS A GLOBAL ENTERPRISE, PROVIDING A UNIQUE EDGE IN OILFIELD SERVICES.

We’ve grown to be one of the world’s largest and technologically advanced oilfield service providers.

We are defined by our inspired thinking and our culture of achievement, delivering a superior customer experience and trusted, reliable performance. Our premium services include contract drilling, directional drilling, underbalanced and managed pressure drilling, rental equipment, well servicing and production services.

Established in 1987, our operations now extend from Canada and the United States to Latin America, the Middle East and Australia.

Over the past quarter-century, we have built a reputation as technology innovators. We were the first in Canada to drill a horizontal well and the first in the world to employ PLC technology, now the industry standard, on an automated drill rig. Those are just two of the many innovations that have kept us at the forefront of technology.

Driving To Zero

DrivingToZeroLogo-Colour_HiRes

Ensign’s goal is to Drive to Zero® – zero safety incidents, zero injuries, zero days off work due to injury. Driving to Zero® means accepting that every incident is preventable and focusing on the operational discipline to achieve zero incidents and injuries.

Our tools and processes have resulted in an increasingly safety‐aware workplace culture and safer operations overall.

Unique to Ensign, our Global Risk Management System (GRMS) captures data from all our operations so performance metrics can be trended, shared and analyzed down to rig level, ensuring every Ensign employee in every location around the globe is actively engaged in best in class safety practices.

Sometimes the most important work we can do is to stop working. Our Stop Work Authority procedure encourages our crews to proactively identify and intervene to stop the unsafe behaviors and conditions that can lead to workplace incidents and injuries.

EnCAAP is a tool to that improves communication between our leaders and their teams in order to better execute core tasks consistently and effectively. It requires that teams effectively engage with each other when they plan tasks and transition to work to ensure safe execution. EnCAAP also helps to identify performance gaps in operational and safety systems and behaviours.
