Abstract:
1. A well stimulation composition comprising a fracturing fluid comprising an aqueous fluid, a guar polymer or a derivative thereof, a cross-linking agent capable of increasing the viscosity of the fracturing fluid by cross-linking the polymer in the aqueous fluid, and a breaking agent; and a gas hydrate controller selected from the group consisting of homopolymers or copolymers of N,N-dialkylamineoethylmethacrylates, homopolymers or copolymers of N-vinyl-N-alkyl amides, homopolymers or copolymers of N-vinyl lactams, homopolymers or copolymers of N-methyl-N-vinylacetamide/lactams, homopolymers or copolymers of N-acyl substituted polyalkeneimines, and mixtures thereof, wherein the gas hydrate controller is present in the composition in an amount effective to control the formation of gas hydrates.
