ABSTRACT:
This invention is directed to a method for recovering residual oil from produced fines and solid materials which are obtained during the production of viscous oil from a formation. The fines and produced materials are injected into a formation with or without fracturing for their disposal. Once in the formation, a non-thermal enhanced oil recovery method is used to remove residual oil from the fines or solid materials. Use of this method provides an inexpensive and environmentally safe method for recovering residual oil from formation fines or solids.
