cleanout runs
The Rhino RHE rathole elimination system is an integrated dual-reamer drilling system that enlarges the borehole while drilling. A passive near-bit reamer is activated at TD, and the rathole is enlarged while drilling to avoid adding extra time to well construction, eliminating the need for a dedicated rathole cleanout run that can add *4 or more hours to drilling time.

The dual-reamer system comprises a Rhino XS hydraulically actuated reamer that is run above MLWD tools, a near-bit Rhino XC on-demand hydraulically actuated reamer, a PowerDrive rotary steerable system, and a customized PDC bit. The system provides on-demand activation of the enlargement system with surface confirmation and offers the ability to work with Schlumberger MLWD real-time data extenders, allowing reamer placement within the MLWD toolstring.
