Rhino

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.

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.

Configurations

• Rhino XS hydraulically expandable reamer
• Rhino XS2 full-cycle expandable reamer
• Rhino XC on-demand hydraulically actuated reamer
• Rhino XM on-demand multiactivated reamer.

Rhino system cutting structures are customizable to the operational requirements of the formation. 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.

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