Underreaming while drilling

Rhino integrated borehole enlargement system

Rhino integrated borehole enlargement system.

Underream and drill in a single run

The rugged, precision-engineered Rhino™ integrated borehole enlargement system comprises a family of hydraulically actuated reamers that save rig time and bring production online faster. Rhino system reamers deliver high-quality, concentric boreholes for close-tolerance and expandable-casing programs. They improve drilling performance by enhancing wellbore quality and reducing the number of trips to underream while drilling.

Customize your cutting structures

Rhino system reamers are customizable to suit any specific underreaming need, including a variety of activation systems and cutting structure options, to achieve operation objectives in numerous challenging applications. As part of the design process, we simulate the behavior of the bit, the underreamer, and each component of the BHA and drillstring to reduce harmful downhole dynamics.

Eliminate extraneous trips

Dual-underreamer Rhino systems facilitate rathole elimination by enlarging the borehole to the top of the directional tool or bit in one run. A passive near-bit reamer is activated at TD, enlarging the rathole while drilling. This eliminates the need for a dedicated rathole cleanout run, which can add 24 hours or more to well construction.
