EnduraTrol Fluid Loss Control Additive | SLB


Fluid loss control additive

Blue fluid around drillstring.

EnduraTrol fluid loss control additive is a nonionic natural polymer designed for use in the Endura drilling fluid system, including in high-salinity and high-hardness brines.

This economical and effective filtration-control additive has some benefits when used as a standalone filtration control additive but is most optimally used in conjunction with a primary fluid loss control additive.
