Well treatment fluids containing a multimodal polymer mixture are disclosed, as are methods for their use. The fluids can contain a fluid, a polymer mixture, and a crosslinking agent. The polymer mixture has a multimodal molecular weight distribution such as a bimodal distribution, a trimodal distribution, or a tetramodal distribution. The polymer mixture can be a mixture of the same polymer, where different batches of different molecular weight distributions are combined. Alternatively, the polymer mixture can be a mixture of different polymers having different molecular weight distributions.
