Abstract
A method of obtaining a hydrocarbon material from a subterranean formation comprises forming a flooding suspension comprising degradable particles and a carrier fluid. The flooding suspension is introduced into a subterranean formation containing a hydrocarbon material to form an emulsion stabilized by the degradable particles and remove the emulsion from the subterranean formation. At least a portion of the degradable particles are degraded to destabilize the emulsion. An additional method of obtaining a hydrocarbon material from a subterranean formation, and a stabilized emulsion are also described.
