Abstract:
Viscosifying proppants including proppant particles coated with a CO 2 -philic coating in which the CO 2 -philic coating has a solvable portion that viscosifies a CO 2 -based fluid when the viscosifying proppant is added to the CO 2 -based fluid are provided. Methods of making viscosifying proppants are also provided that include coating proppant particles with a precursor material of a CO 2 -philic material, and polymerizing the precursor material to form a viscosifying proppant. Viscous hydraulic fracturing fluids include a CO 2 -based fluid and the viscosifying proppants and methods of treating subterranean formations that include contacting a subterranean formation with a viscous hydraulic fracturing fluid and propagating at least one subterranean fracture are also provided.

Claim (Index 1):
A method of preparing a viscous hydraulic fracturing fluid, the method comprising:\n combining a CO 2 -based fluid having a first viscosity at a pressure of less than or equal to 1000 pounds per square inch (psi) and a temperature of less than or equal to 32\u00b0 C. with a viscosifying proppant comprising proppant particles coated with a CO 2 -philic coating that has a solvable portion that viscosifies the CO 2 -based fluid to produce a viscous hydraulic fracturing fluid having a second viscosity at a pressure of less than or equal to 1000 psi and a temperature of less than or equal to 32\u00b0 C. that is at least 25% greater than the first viscosity, in which the second viscosity is measured at least 30 minutes after combining the CO 2 -based fluid and the viscosifying proppant.
