Abstract
A hydraulic fracturing composition includes: a superabsorbent polymer in an expanded state; a plurality of proppant particles disposed in the superabsorbent polymer; an additive comprising a surfactant, a viscose polymer, or a combination thereof, and a fluid to expand the superabsorbent polymer into the expanded state. A process for disposing a plurality of proppant particles in a fracture comprises: disposing a hydraulic fracturing composition in a downhole environment; forming a fracture; disposing the hydraulic fracturing composition in the fracture; breaking the superabsorbent polymer after forming the fracture; and releasing the plurality of proppant particles from superabsorbent polymer. The process also comprises injecting a proppant-free fluid and a proppant-containing fluid in an alternating order into a subterranean formation.
