To prevent downhole equipment plugging and ensure safe fluid and cement pumping through bottom hole assemblies (BHAs), SLB locally designed and manufactured a high-pressure filter unit (HPFU) tailored to the operator's exact requirements on the Norwegian Continental Shelf (NCS).

Offshore operators on the NCS have requested HPFUs for cementing operations where there was a risk of clogging downhole equipment, such as BHAs. Faced with drilling through faults and high-risk loss zones in this area, an operator required a unit specific to their technical requirements to ensure safe cement pumping.

SLB responded by designing and manufacturing an HPFU locally in Norway that met the operator’s technical specifications for safely pumping fluids and cement through BHAs. Designed to filter any debris, such as cement rocks, from fluid and slurry at surface before it travels downhole, the HPFU contains a high-pressure strainer that can be replaced with different mesh sizes depending on requirement, ranging from 500 to 5,000 um.
