Kwik-Seal F/M/C


Appearance Silver/Brown/black/grey Flakes and Granules
Specific Gravity 0.8-1.3
pH (1% Solution) NA
Solubility Insoluble in cold water


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.


  • Easy to mix through hopper
  • Compatible with most types of regular water-based and oil-based muds
  • Stable up to 300°F
  • Provide sufficient sealing in fracture zones, vugular formations and thief areas


Main function of Kwik-Seal F/M/C is to minimize or cure downhole losses in fracture, vugs or permeable zones. Based on severity of losses, type and optimum concentration of Kwik-Seal is selected and pumped. It can be used in workover operations as well as drilling.

Safety tips

First and Measures Eye Contact: Check for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Skin Contact: Wash with soap and water. Cover the irritated skin with an emollient. Get medical attention if irritation develops. Inhalation: If dust is inhaled, remove from contaminated area.
  • Encourage patient to blow nose to ensure clear passage of breathing.
  • Immediately give a glass of water.
  • First aid is not generally required. If in doubt, contact a Poisons Information Centre or a doctor
