ABSTRACT:
Compositions and methods for modifying the permeability of subterranean formations are shown. The compositions and methods generally comprise forming a dispersion of water swellable crosslinked polymer particles, adding the dispersion to a carrier fluid to form a treatment fluid, and injecting the treatment fluid into the subterranean formation. The particles are made by polymer emulsion or microemulsion processes, resulting in particles that are much smaller in size than that of the formation pore strictures. Upon injection, the particles become trapped in the formation, and upon flowback of water, the particles swell in size and adsorb onto the formation, forming a film and restricting further fluid flow.
