摘要
Viscosifying proppants including proppant particles coated with a CO2-philic coating in which the CO2-philic coating has a solvable portion that viscosifies a CO2-based fluid when the viscosifying proppant is added to the CO2-based fluid are provided. Methods of making viscosifying proppants are also provided that include coating proppant particles with a precursor material of a CO2-philic material, and polymerizing the precursor material to form a viscosifying proppant. Viscous hydraulic fracturing fluids include a CO2-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.
