Product Details

Product Description

*The roller centralizers are designed in rigid body with straight or spiral blades.

*Rollers provide low drag to get casing, liners, or screens to bottom successfully with reduced rig time and costs.

*Minimal roller-contact area in open hole applications reduces the risk of differential sticking and provides optimal standoff for increased operational efficiency.

*The roller centralizer is used in deviated and horizontal wells.
