Underreaming while drilling
Rhino integrated borehole enlargement system
Overview
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.
Multiple activation mechanisms
Mechanical and hydraulic activation available within the Rhino system family
Configurable cutting structure and opening size
Dynamic cutter block design for specific applications
Advanced bit and reamer optimization
IDEAS™ integrated dynamic design and analysis platform modeling
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.
Cutter Blocks: 3D Innovations for the Best Performance
From the AxeBlock™ torque-reducing ridged diamond element cutter block to stabilizer blocks, our industry-leading family of cutter blocks combine the best cutters with a dynamically stable design for the best performance in a variety of formations—all in a variety of BHA configurations.
