  • Hydraulic fracturing fluids with an aqueous base fluid and clay stabilizer and methods for hydraulic fracturing using the same
    Patent number: 11608467
    Abstract: According to one or more embodiments of the present disclosure, a method for hydraulic fracturing includes pumping a hydraulic fracturing fluid through a wellbore into a subterranean formation at a pressure greater than a fracturing pressure of the subterranean formation. The hydraulic fracturing fluid may include an aqueous base fluid and a clay stabilizer consisting of one or more polyethylene polyamines having a first structure H2NCH2CH2(NHCH2CH2)xNH2, where x is an integer greater than or equal to 3. The amount of the clay stabilizer may be from 1 lbm/bbl to 20 lbm/bbl relative to the total volume of the hydraulic fracturing fluid. The average molecular weight of the polyethylene polyamines in the hydraulic fracturing fluid having the first chemical structure may be from 200 g/mol to 400 g/mol. All of the polyethylene polyamines in the hydraulic fracturing fluid having the first chemical structure may be encompassed in the clay stabilizer.
