BI-CENTER

Bi-Center bits are used to increase the wellbore diameter, to replace under reaming, to help control trouble zones, and for expandable tubulars. They are also specifically designed to reduce the risk associated with operating hole openers and under reamers.

Features / Benefits

One Piece Design
Shortens overall length of the bit for better directional control if needed and enhances the hydraulic efficiency of the bi-center bit.

Force3 Cutters
Superior proprietary cutter testing methods provide the best cutter for any challenge.

Cutting Structure Drill Out Feature
Varel’s Casing Saver Design cutting structure feature provides a reliable drill out mode while protecting both the cutting structure when inside the casing as well as the casing itself.

Force Balancing
During the design process the pilot and reamer cutting structure are force balanced as a single unit. This provides increased drilling efficiencies in both vertical and deviated wells.
