METHODS OF TREATING LOST CIRCULATION ZONES

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 los...

More Information
Summary: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.
