Abstract
Methods for hydraulic fracturing may utilize a fracturing fluid that includes a dual-polymer base fluid for all stages of a hydraulic fracturing operation. The dual-polymer base fluid includes a polysaccharide polymer and a polyacrylamide polymer. The dual-polymer base fluid and a crosslinker may be pumped into a wellbore drilled into a formation. A pump rate may be increased to induce one or more fractures in the formation. Proppant may be added to the dual-polymer base fluid while pumping. The proppant may be injected into the one or more fractures. The pump rate may then be reduced, and the dual-polymer base fluid may flow back into the wellbore.
