Abstract
A fracturing fluid and method of including a cellulose polymer derivative, a diol functional group, and a borate crosslinker. The diol functional group may be a cis-diol functional group, a 1,2-diol functional group, or a 1,3-diol functional group. The cellulose polymer derivative further may include a hydroxyethyl group or a hydroxypropyl group. The fracturing fluid may also include at least one metallic crosslinker. The method may also include the steps of adding a pH adjusting agent, at least one breaker, a surfactant, a scale inhibitor, and/or a bactericide to the fracturing fluid, or mixing the fracturing fluid using mixing equipment or wherein the fracturing fluid is introduced into a subterranean formation using one or more pumps.
