Abstract

Lost circulation material (LCM) compositions may include an epoxy resin, an emulsifier comprising a polyaminated fatty acid, water, a crosslinker, and an optional cementitious and/or weighting agent. These LCM compositions may have a density of from about 63 pounds per cubic foot (pcf) to about 99 pcf and may be capable of being injected through a drill bit of a drill string into a lost circulation zone in wellbores. Corresponding methods of eliminating or reducing lost circulation in a lost circulation zone from a well may include introducing these LCM compositions into the well.
