On-demand multiactivated reamer
Achieve more reliability with a truly on-demand hydraulically activated reamer—more reliable than third-party reamers.
Dual-reamer rathole elimination system
The Rhino RHE dual-reamer rathole elimination system is an integrated dual-reamer drilling system that enlarges the borehole to the top of the directional tool or the bit in one run. A passive near-bit underreamer 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 24 or more hours to drilling time.
The dual-reamer system comprises a Rhino XS2 full-cycle expandable reamer or a Rhino XS hydraulically expandable 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. It also offers the ability to work with Schlumberger MLWD real-time data extenders, enabling underreamer placement within the MLWD toolstring.
