Dual-diameter drift and drill reamer
Designed to enhance rotary drilling performance, Quad-D dual-diameter drift and drill reamers can be run with various BHA configurations on rotary steerable systems (RSSs).
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, optimizing hole quality while drilling. The reamer provides directional and BHA flexibility for precise control of the wellbore, diameter control for a full-gauge hole, and formation-specific design for peak drilling efficiency.
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.
