Drill-N-Ream®
Introduction
Drill-N-Ream® is a patented, dual-stage wellbore conditioning tool that reams while you drill.
The DNR’s opposing eccentric PDC stages work in unison to centralize and stabilize cutting forces, smoothing out ledges, doglegs, and tortuosity as the well is drilled, eliminating dedicated reaming runs.
Proven on thousands of wells and more than 150 million feet of conditioned hole, the Drill-N-Ream® reduces torque and drag, extends lateral reach, and delivers smoother casing runs at a lower cost per foot.
Ream While You Drill
Conditions the wellbore during the drilling process, elimination of dedicated reaming runs and reduces the need for backreaming.
Motor and RSS Compatible
Compatible within conventional motor or rotary steerable BHAs without changing drilling parameters or how you operate.
Proven at Scale
Field-proven on thousands of wells and more than 150 million feet of conditioned hole worldwide.
How It Works
A Straighter Path to Target Depth
Wellbore tortuosity, ledges, and doglegs add torque and drag, restrict weight transfer, and put casing runs at risk. The Drill-N-Ream® conditions the wellbore during the drilling process, removing these problems at the source.
Its dual-stage design enlarges borehole drift up to ¼" over bit size, while progressive blades shear the formation with minimal reactive torque. A specialized profile relief draws the PDC cutting zone directly into the formation, and diamond domes protect the casing and cutting structure during trips and drill outs.
The result is a consistently smoother wellbore: reduced torque and drag, extended lateral reach, and casing to TD without a dedicated reamer run.
