Abstract
Methods of continuously forming and suspending consolidatable resin composition coated particulate material in a gelled aqueous carrier liquid and transporting the coated particulate material by way of the gelled aqueous carrier liquid to a zone in which the sand is consolidated. In accordance with the methods, substantially continuous streams of a gelled aqueous carrier liquid, uncoated particulate material, a resin composition which will subsequently harden and a surface active agent are admixed whereby the particulate material is continuously coated with the resin composition and suspended in the gelled aqueous carrier liquid.
Claims17
A method of continuously forming and suspending consolidatable resin composition coated particulate material in a gelled aqueous carrier liquid comprising intermixing substantially continuous streams of said gelled aqueous carrier liquid, prepared by admixing from about 20 to 120 pounds of a hydratable polysaccharide having a molecular weight of from about 100,000 to about 4,000,000 with an aqueous carrier liquid per 1000 gallons of said carrier liquid, a particulate material, a resin composition which will subsequently harden and a surface active agent whereby said particulate material is substantially continuously coated with said resin composition and suspended in said gelled aqueous carrier liquid, said resin composition comprising a hardenable polyepoxide resin, a hardening agent for said resin, a substantially water immiscible reactive diluent and substantially water immiscible non-reactive diluent for said resin, said reactive and non-reactive diluents being present in said resin composition in amouns sufficient to lower the viscosity of the resin composition to a level in the range of from about 100 to about 800 centipoises at ambient temperature.
A method of continuously forming and suspending consolidatable resin composition coated particulate material in a gelled aqueous carrier liquid comprising intermixing substantially continuous streams of an aqueous carrier liquid gelled by the addition of a polysaccharide polymer thereto, a particulate material, a surface active agent including a noncationic surfactant and a resin composition which will subsequently harden whereby said particulate material is substantially continuously coated with said resin composition and suspended in said gelled aqueous carrier liquid, said resin composition comprising a hardenable polyepoxide resin, at least one substantially water immiscible first diluent for said resin, a second diluent which is non-reactive with said resin and a hardening agent for said resin, said diluents being present in said resin composition in an amount sufficient to lower the viscosity of the resin composition to a level in the range of from about 100 to about 800 centipoises at ambient temperature and said polysaccharide is present in said aqueous carrier liquid in an amount of from about 20 to about 120 pounds per 1000 gallons of said carrier liquid.
