Fine Lost Circulation Material
Lost circulation materials (LCM) are used in the mitigation and remediation of seepage, partial, or complete loss of drilling fluid from the hole into rock formation. Fine lost circulation materials (lb/bbl) can pass through 20-mesh screen. On the contrary, coarse LCM cannot pass through 20-mesh screen.
