Near-Bit Placement

Type H — Near Bit

Designed for placement immediately above the bit, eliminating the need for a pilot section and helping reduce drilling time and operational risk.

Its compact design allows it to run below a downhole motor or point-the-bit rotary steerable system (RSS) in directional applications.

Compact & Reliable

Type S — String

A compact solution designed for simplicity and reliability, capable of increasing pilot size by up to 50%, even in smaller diameters.

Reamer bodies staged on the shop floor

Field-Ready Assemblies

Built & Inspected for the Job

Every reamer body and connection is staged, measured, and verified before it leaves the shop floor.

Fixed Cutter Reamers

Three enlargement platforms engineered for hole centering, staged operation, and reduced differential-sticking risk.

  • Fixed Cutter Reamer

    TPXR™

    Features a pronounced profile designed to improve hole centering. It can be combined with PDC, steel tooth, or insert bits to achieve larger bicenter diameters while reducing design, cost, and availability constraints.

  • Fixed Cutter Reamer

    TPCR™

    A versatile solution that can operate as a two-stage bit or stand-alone hole opener.

  • Fixed Cutter Reamer

    DuoForce™

    An efficient, cost-effective enlargement solution for rotary and steerable systems, designed to reduce the risk of differential sticking.

Flexible enlargement solutions for complex wellbore requirements.
