Reduce downhole torque and vibration with Cougar roller reamers.
Well tortuosity and torque can create a less stable environment in vertical and directional drilling applications. Roller reamers are often needed to enlarge the borehole or smooth rough ledges that can increase wear and tear on equipment and increase risk of not reaching total depth.
Cougar roller reamers are engineered for durability and reliability, even under the most severe reaming conditions. Offering many of the benefits of taper blade reamers, roller reamers also provide a rolling surface along the wellbore, which reduces torque, allows for greater energy transfer to the bit, and increases ROP.
We design and build each roller reamer to your specifications from heat-treated, stress-relieved steel at our Canadian facilities. Each one must pass our thorough inspections and testing for quality assurance before shipment to your location.
