MICA Flakes
MICA is essentially naturally Occurring Muscovite Mica flakes seized in Fine Medium and Coarse grades essentially used in the Loss Circulation applications during Drilling Operations
Common Name: Mica flakes
Application:
MICA FLAKES can be 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.
Advantages:
- Effective Low-cost LCM.
- Does not adversely affect the properties of OBM or WBM.
- Generally Inert Material with no reactions to Hydrocarbons, acids, Brines.
