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 improving 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 system cutting structures are customizable to the operational requirements of the formation. As part of the design process, the behavior of the bit, the underreamer as well as each component of the BHA and the drillstring is simulated 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.
Field proven with more than 8,500 runs and 13 million ft reamed worldwide as of April 2019, Rhino system reamers can be customized for a variety of challenging applications, including
