Mica LCM Coarse


Mica flakes, seized in Fine and Coarse grades, is essentially used in Loss Circulation applications during drilling operations. Mika flakes can be used in water-based and oil based mud drillings operations as a mud additive chemical to prevent loss of circulation and seepage. Mica is added in particular to seal-off the loss circulation zones. The platy structure of mica facilitates the overlapping of particles to form a layer or wall and acts as a sealant that bridges the openings. The use of mica helps to seal porous formations and contributes to regain circulation, thus keeping the solids in suspension.
