MICA is made available in fine (F), medium (M) and coarse (C) grades.

MICA have been preferably used in water-based and oil based oil-well drillings operations as an additive mud chemical to prevent loss of circulation and seepage. Mica is specially added to seal-off the lost 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 keeping the solids in suspension.
