High viscosity complexed aqueous gels and methods and additives for forming such gels utilize solid crystalline organic titanate complexing agents. The organic titanate complexing agents react over broad pH and temperature ranges and the reaction rates are controlled by the rate of dissolution of the agents. A solid crystalline complexing agent reacts with aqueous gels containing hydrated organic polymers such as polysaccharides and polyacrylamides to form the aqueous gel into a high viscosity complexed aqueous fluid. In addition, solid additives containing one or more hydratable organic polymers and the complexing agent are combined with an aqueous fluid to form a highly viscous complexed aqueous gel at a desired pH and/or temperature. High viscosity complexed aqueous gels and methods of forming such gels utilizing the complexing agents and additives also are provided. The complexing agents are solid crystalline organic titanate monomers, homopolymers of such monomers and mixtures of such monomers and homopolymers such as titanium bis acetylacetone-enolate dihydroxide. 9 claims.
