Kwik-Seal F/M/C is a common mixture of loss circulation materials which is applicable in both water-based and oil-based drilling fluid systems. Kwik-Seal F/M/C is composed of Mica flakes, saw dust, sized wood particles and etc. It can alleviate downhole loss circulation with severity of up to 150 BBL/Hr. Kwik-Seal F/M/C is available in three different sizes (fine, medium and coarse). It is better to pumped as LCM pills, and functions more efficiently when it is used with other type of LCMs such as NUT-PLUG, MICA and Sized Calcium Carbonate.
