Hydraulic fracturing fluids include an aqueous fluid, an acrylamide-based polymer, and a crosslinker that crosslinks the acrylamide-based polymer to form a crosslinked gel. The crosslinker includes a cellulose backbone functionalized with branch structures. The branch structures comprise oxiranylalkanol branches or polyoxiranylalkanol branches. Methods for preparing the hydraulic fracturing fluids and methods for treating subterranean formations with the hydraulic fracturing fluids are disclosed.

Branched cellulose-based hydraulic fracturing fluid crosslinker

Hydraulic fracturing fluids include an aqueous fluid, an acrylamide-based polymers, and a hyperbranched crosslinker that crosslinks the acrylamide-based polymer to form a crosslinked gel. The hyperbranched crosslinker includes a hyperbranched polyethyleneimine polyoxiranylalkanol having a weight-average molecular weight from 10 kDa to 1500 kDa. The hyperbranched crosslinker may be a product of reacting a hyperbranched polyethyleneimine with an oxiranylalkanol to obtain the hyperbranched polyethyleneimine polyoxiranylalkanol. In examples, the oxiranylalkanol is glycidol. Methods for preparing the hydraulic fracturing fluids and methods for treating subterranean formations with the hydraulic fracturing fluids are disclosed.
