Rhino XS

Hydraulically Expandable Reamer

Superior borehole quality

The Rhino XS hydraulically expandable reamer can be configured for a wide range of borehole sizes and borehole enlargement applications, including extended intervals drilled with advanced rotary steerable systems (RSS), extended-reach (ERD) wells, highly abrasive formations, and loosely consolidated formations.

Application-specific and robust construction

The single-piece body of the Rhino XS reamer enables a higher tensile- and torque-load capacity. The tool features a symmetrical, concentric arrangement of three PDC cutter blocks that improve ROP without sacrificing durability.

How It Works

The Rhino XS reamer is primarily used with RSSs. Reliable hydraulic actuation is provided by the Z-Drive reamer cutter block deployment system. When activated from an activation ball dropped at surface, the Z-Drive system pushes the cutter blocks upward and radially outward to the fully open position, facilitating rapid cutout and ensuring a full-gauge, concentric borehole. When pumping stops, the cutter blocks retract. Dependable retraction of the cutter blocks helps avoid stuck BHAs.

Cuttings evacuation

Integrated jet nozzles and flow paths improve evacuation of cuttings while drilling. The reamer enables full flow through the BHA in both open and closed positions.
