SP Casing Brush

Ensure effective casing cleaning with high-performance tools

The Sharp Razor SP casing brush is a durable tool designed for deepwater, deep, and deviated well applications. It is used to brush and clean the interior diameter (ID) of casing and remove scale, rust, mud residue, and any other particles of debris. The tool can be run by itself or as an integral part of a complete wellbore cleaning and displacement system with circulation tools, scrapers, magnets, filters, and bit.

The casing brush features a one-piece mandrel design without any internal connections. The tensile and torque ratings of the tool are higher than those of the tool joint. This allows the tool to be used in deepwater wells, deep wells, or deviated wells in which higher tensile and torque rating are required.

One feature of the tool is its high allowable rotation speed. Allowing drillpipe to rotate up to 150 rpm significantly increases the cleaning efficiency and allows the tool to be used in the drilling or milling applications in which a high rotational speed is required.

The tool also provides large ID and annulus flow areas. It allows more effective circulation and displacement operations.

The non-rotational stabilizers and brush sleeve, plus the field-proven brush technology, prevent wear or damage to the casing wall, while allowing for maximum casing ID cleaning in straight or high-angled holes. The brush is not vulnerable to chemical or acid attack.
