Quad-D Dual-Diameter Drift and Drill Reamer

Overview Product Sheets

Maximize performance in rotary applications

Quad-D dual-diameter drift and drill reamers are designed to maximize performance in rotary applications. This tool is intended to be run with various BHA configurations on rotary steerable systems (RSSs).

Pilot conditioning optimizes hole quality while drilling

The Quad-D reamer is positioned in the drillstring at a distance from the pilot bit, determined by the application. The pilot conditioning section ensures centralization and stabilization, with the aim of optimizing hole quality while drilling. The Quad-D reamer provides directional and BHA flexibility for precise control of the wellbore, diameter control for a full-gauge hole, and formation-specific design for optimized drilling efficiency.

Make just one trip with drillout capability

The Quad-D reamer’s ability to drill out cement prior to underreaming means that two separate trips in the hole can be replaced with one.
