Abstract:
A lost circulation material (LCM) is provided having a nanosilica dispersion. The nanosilica dispersion of the LCM may form a gelled solid after interaction with a formation over a period. Methods of lost circulation control using LCMs are also provided.

Claim (Index 1):
A method to control lost circulation in a lost circulation zone in a carbonate formation, comprising:\n introducing a lost circulation material (LCM) into the wellbore such that the LCM contacts the lost circulation zone and reduces a rate of lost circulation into the lost circulation zone as compared to a period before introducing the LCM, wherein the LCM consists of an acidic nanosilica dispersion and at least one of: calcium carbonate particles, fibers, mica, and graphite.
