A liquid gel concentrate for forming a high viscosity treating fluid is provided which can be premixed and stored before being used. The concentrate is comprised of an aqueous formate solution, at least one hydratable polymer which yields viscosity upon hydration and optionally an inhibitor having the property of reversibly reacting with the hydratable polymer in a manner whereby the rate of hydration of the polymer is retarded. Upon the selective reversal of the hydration inhibiting reaction the polymer is hydrated and high viscosity yielded thereby. The concentrate can be diluted with water to hydrate the hydratable polymer and form a large volume of high viscosity treating fluid.

Formate based liquid gel concentrates

The present invention provides improved methods of consolidating particulate material in a subterranean zone penetrated by a well bore. The methods basically comprise the steps of coating the particulate material with a hardenable resin composition and irradiating the hardenable resin composition coating on the particulate material with microwaves to thereby accelerate the hardening of the resin composition whereby the particulate material is rapidly consolidated into a stationary permeable mass.
