Loss Circulation Material

Mica is a group of silicate minerals whose outstanding physical characteristics is that individual mica crystals can easily be split into extremely thin elastic plates.

Mica is used in the well-drilling industry as an additive to drilling fluids. The coarsely ground mica flakes helps prevent the loss of circulation by sealing porous sections of the drill hole and use in other products such as drywalls, paints, fillers, especially in parts for automobiles, roofing, and shingles, as well as in electronics.

Fluids loss additives such as solid particles and water-thickening polymers may be added to the drilling mud to reduce fluid loss from the well bore to the formation. Insoluble and partially soluble Fluids loss additives includes mica, bentonite, carefully sized particles of calcium borate , starch, crushed walnut hulls etc.
