Underreaming while drilling

Rhino integrated borehole enlargement system

Overview

Underream and drill in a single run

Operators face increasing pressure to improve drilling efficiency and reduce rig time without compromising borehole integrity. The Rhino™ integrated borehole enlargement system enables single-run underreaming and drilling, eliminating redundant trips and accelerating well delivery. With more than 8,000 runs and 13 million ft reamed, the Rhino system delivers reliable performance across the most demanding formations.

Precision-engineered integration for optimal performance

The Rhino system is designed to integrate seamlessly into the BHA. Each reamer is modeled using the IDEAS™ integrated dynamic design and analysis platform to predict behavior and mitigate vibration. Activation can be triggered mechanically, hydraulically, or via wired command—delivering flexibility across well types. Dual-reamer configurations facilitate rathole elimination while drilling, improving operational efficiency and reducing overall well cost.

Applications

Precision-engineered underreaming for complex drilling environments

Swelling or unstable formations

Improve borehole quality and reduce risk of stuck pipe.

Extended-reach and high-inclination wells

Maintain borehole stability while maximizing ROP.

Highly abrasive environments

Maintain durability and cutting efficiency in abrasive formations.

Deep water

Ensure reliable performance and reduced trip time in high-pressure, deepwater wells.

Using three reamers on a single BHA saves PETRONAS Suriname 16 hours.
