Abstract: Provided is a loss circulation material that may consist essentially of an acidic nanosilica dispersion and an activator. The acidic nanosilica dispersion may consist of acidic silica nanoparticles, stabilizer, and water, and may have a pH in a range of 3 to 6. The activator may be one or more from the group consisting of sodium bicarbonate, sodium chloride, or an amine salt. A method is provided for controlling lost circulation in a lost circulation zone in a wellbore comprising introducing the loss circulation material and forming a gelled solid from the loss circulation material in the lost circulation zone.

Abstract: A method of treating a lost circulation zone may include positioning a cured lost circulation material composition in the lost circulation zone of a subterranean natural resource well to produce a barrier operable to mitigate wellbore fluids from passing into the lost circulation zone. The cured lost circulation material composition may be a foam comprising a gas phase and a liquid phase. The cured lost circulation material composition may include a cured bisphenol epoxy resin, one or more surfactants positioned at the interface of the liquid phase and the gas phase of the foam and carbon dioxide in the gas phase of the foam. The cured bisphenol epoxy resin may be a reaction product of a bisphenol epoxy resin system including uncured bisphenol epoxy resin, one or more curing agents, and optionally, a diluent. The carbon dioxide may be a reaction product of one or more carbon dioxide gas-generating compounds.

Abstract: A lost circulation material (LCM) composition for sealing lost circulation zones in wellbores may include 50 weight percent to 97 weight percent epoxy resin, 2 weight percent to 30 weight percent curing agent, 0.1 weight percent to 40 weight percent weighting material, and 0.1 weight percent to 20 weight percent amide accelerator. The LCM composition may have a density of greater than or equal to 1121 kilograms per cubic meter and may be capable of being injected through a drill bit of a drill string into the lost circulation zone. The amide accelerator may enable the viscosity of the LCM composition to be reduced while providing a reduced cure time. The LCM compositions are suitable for treating high-injectivity lost circulation zones.
