Casing Brush

It is a heavy-duty wellbore clean-up brush suitable for all downhole conditions with robust, high-performance features.

Run separately or as part of a comprehensive wellbore clean-up, the brush is designed to effectively scrub cement and other debris from the casing wall through reciprocation.

The brush segments are arranged to allow unhindered fluid bypass while circulating through clearly defined flow paths.

The alloy bronze bearings feature both axial and radial elements to allow extended rotation in harsh environments, preventing tool and casing wear.

 

Applications

Pre-completion wellbore clean-up

Workovers and sidetracking

Abandonment

Drilling/milling cement plugs

 

Features

Stainless steel crimped wire brushes safely scrub the casing wall to remove residual cement, scale, and other debris

Centralizers provide centralization and allow rotation of the tool body without casing wear

Large flow area between the exterior of the tool and the ID of the casing, which reduces equivalent circulating density and guards against surge

Available with all API and premium drill pipe connections

 

Advantages

A properly executed wellbore clean-up mitigates risk during completion operations and the productivity of the well

Prepare casing wall to ensure packer setting while RIH

Prepare casing wall to ensure packer element sets and mitigate premature elastomer failure

Assists in chemical cleaning action
