SP Mica Course, medium, Fine
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, fillers . . . . . . . .
- Course SP Mica
- Medium SP Mica
- Fine SP Mica
This grade would likely contain larger mica particles, suitable for bridging larger voids or fractures encountered in the formation. Course SP Mica is typically used in situations where there are substantial losses of drilling fluids into highly permeable formations or fractured zones.
Medium-grade SP Mica would consist of mica particles of intermediate size. It could be applied in scenarios where the formation porosity or fractures are of moderate size, requiring a balance between bridging capability and flowability within the drilling fluid.
Fine-grade SP Mica would contain smaller mica particles. It might be employed in situations where the formation has smaller voids or fractures, necessitating a finer material to effectively seal off the loss circulation zones. Fine SP Mica can help achieve a smoother seal or finish in the drilling process.
