Rhino® AB Reamer

The Rhino AB (At Bit) Reamer extends SMITH’s industry leading borehole enlargement technology to directional and downhole motor applications. For below-the-motor hole enlargement applications with challenging profiles, the Rhino AB delivers a high-quality, concentric wellbore.

The Rhino AB is designed for hole enlargement needs in marginal or brownfield developments where economic constraints preclude the use of more expensive rotary steerable systems, and the hole quality delivered by eccentric reaming tools compromises the ability to successfully run and cement casing strings.

Features and Benefits

·         Concentric PDC cutter blocks ensure a high quality full gauge concentric wellbore

·         Differential hydraulic activation allows circulation without opening the tool

·         Dependable cutter block retraction to avoid stuck BHAs

·         IDEAS cutting structures ensure optimum ROP while minimizing vibration

·         Integral backreaming capability

·         Minimizes rathole length

·         Minimized shoulder to shoulder length and weight for placement below motor in directional applications

Applications

• Simultaneous drilling and hole enlargement in operations where reliability is critical
• Enlargement operations run with directional drilling assemblies

Ordering instructions

• Expanded diameter
• Size and weight of casing to be run through
