Abstract: 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.

Abstract: Methods of preparing a crosslinked hydraulic fracturing fluid include combining a hydraulic fracturing fluid comprising a polyacrylamide polymer with a plurality of coated proppants. The plurality of coated proppants include a proppant particle and a resin proppant coating on the proppant particle. The resin proppant coating includes resin and a zirconium oxide crosslinker. The resin includes at least one of phenol, furan, epoxy, urethane, phenol-formaldehyde, polyester, vinyl ester, and urea aldehyde. Methods further include allowing the zirconium oxide crosslinker within the resin proppant coating to crosslink the polyacrylamide polymer within the hydraulic fracturing fluid at a pH of at least 10, thereby forming the crosslinked hydraulic fracturing fluid.

Abstract: Proppant particulates like sand are commonly used in hydraulic fracturing operations to maintain one or more fractures in an opened state following the release of hydraulic pressure. Fracturing fluids and methods of hydraulic fracturing may also use proppant particulates composed of high-flow polyolefin coated mineral particles (referred to as high-flow polyolefin coated mineral proppant particulates). In some instances, the high-flow polyolefin-coated mineral proppant particulates have a particle density of equal to or less than about 1.35 grams per cubic centimeter, and further may be prepared using a one-pot hot melt process.

Abstract: A treatment fluid comprising a peroxide source and a perovskite family catalyst is provided. The treatment fluid can be useful in process for breaking the gelled component of a gelled fluid used in downhole operations. In particular, the treatment fluid can be useful in fracturing operations where it can not only break the gelled component of the fracturing fluid but the gaseous oxygen generated by the peroxide source and perovskite family catalyst can be used to further fracture a subterranean formation.
