    • The current application discloses fluids and methods for treating a subterranean formation penetrated by a wellbore, such as hydraulic fracturing. In one aspect, there is provided an oilfield fluid comprising chitosan at an amount sufficient to inhibit the growth of bacterial in the oilfield fluid. In another aspect, there is provided a method of preserving an oilfield fluid containing adding chitosan at a concentration that is sufficient to inhibit the growth of bacteria in the oilfield fluid. In a further aspect, there is provided a method of treating a subterranean formation penetrated by a wellbore, comprising preparing a treatment fluid, adding chitosan at a concentration sufficient to inhibit the growth of bacteria in the treatment fluid, introducing the mixture to the subterranean formation, and treating the subterranean formation with the mixture.
