Riser brush is designed to mechanically assist in cleaning subsea risers by polishing and removing mud film and other restrictive material from the inner wall diameters. The brush provides superior riser wall cleaning without reducing circulating flow area. Fluid flow can either be directed around the outer diameter of the tool, self cleaning the bristles, or under the brush sleeves helping to eliminate potential for pressure drop. The Riser Bristle Tech brush can be integrated into a single-trip system in combination with other wellbore cleaning tools during the displacement process.
It can also be run as a standalone device for offline riser cleanout runs.
