Roller Reamer

Roller Reamer

Roller Reamers are downhole drilling tools designed to maintain wellbore gauge, stabilize the Bottom Hole Assembly (BHA), reduce torque and drag, and minimize differential sticking during drilling operations. Equipped with rotating hardened steel rollers, they effectively ream tight spots, remove ledges, and reduce friction between the drill string and the wellbore wall. Roller Reamers are suitable for both vertical and directional drilling in onshore and offshore oil and gas operations.

Our Roller Reamers are available for sale and lease, providing reliable performance for exploration, development, workover, and drilling projects.

Applications

Maintaining full-gauge wellbore diameter.

Reducing drill string torque and drag.
