Clean the riser even through a restricted ID

The riser cleaning tool allows operators to clean debris from the riser. The tool is effective even when a restricted ID above the riser, such as a surface blowout preventer (BOP) stack, prevents the entry of large-diameter tools. The riser cleaning tool is designed to pass through ID restrictions, yet still provides aggressive mechanical scratching and wiping to remove even the most stubborn  fluid sheaths that accumulated. The debris is extracted from the riser with the associated integral junk bucket.


The tool is used prior to any completion operation requiring a clean riser or when displacing drilling fluid from the riser. It ensures removal of the sheath of debris-laden fluids from the riser wall and prevents the remaining fluid sheath from depositing solids on sensitive completion string components, thus helping eliminate the risk of expensive and time consuming NPT.
