Maximize riser cleaning without compromising flow area
The CleanWell® Riser Bristle Tech® 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 reduce the 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 can be run as a stand-alone device for off-line riser cleanout runs.
While drilling a pre-salt offshore deepwater appraisal well in Brazil, a major operator found
that the well needed a robust and efficient single-trip wellbore cleanout system. Due to
anticipated well challenges during the completion, they needed to find a system that was
capable of drilling cement, shoetrack, and reaming while still providing an effective wellbore
