Technical Bulletin

Description : Loss Circulation Material (LCM) mica products an excellent choice for the oil and natural gas drilling mud and field services industries.

Application : Used in the Loss Circulation applications during drilling operations.

* RXSOL LCM Mica  products can be used in both oil and water-based drilling muds to prevent loss of circulation.  Our mica can be used in horizontal , directional and veritcal drilling applications where it aides in sealing loss circulation zones with its flakey, flat structure and increases borehold stability.

* Secondary but significant benefits of LCM Mica include improved sample recovery, formation pressure control, cuttings dropped more easily in a surface disposal area, minimization of drilling fluid losses into formations and reduction of wear and corrosion on the drilling equipment.

Advantage :

* Chemically inert except to hydrofluoric and concentrated sulfuric acids

* Used to treat all forms of loss circulation

*Flat, flakey structure aides in lubrication

*Compatible with other LCM products

*Effective low cost LCM
