LCM-NS
Nutshell Lost Circulation Material
Granular bridging material used in lost-circulation pills and preventive LCM programmes in water- and oil-based muds.
Application
Partial losses and preventive wellbore strengthening where medium-grade granular LCM is specified. Particle size must match fracture width.
Technical characteristics (quality certificate)
