Abstract
A hydraulic fracturing composition includes: a superabsorbent polymer in an expanded state and configured to break in response to a breaking condition; a plurality of proppant particles disposed in the superabsorbent polymer prior to release of the plurality of proppant particles from the superabsorbent polymer in response to breaking the superabsorbent polymer; and a fluid to expand the superabsorbent polymer into the expanded state. The hydraulic fracturing composition can be made by contacting a superabsorbent polymer with a fluid to expand the superabsorbent polymer into an expanded state; and disposing a plurality of proppant particles in the superabsorbent polymer to make the hydraulic fracturing composition.
