SYSTEMS AND METHODS FOR ENHANCING PRODUCTION OF VISCOUS HYDROCARBONS FROM A SUBTERRANEAN FORMATION

摘要

Methods of selecting a composition of a hydrocarbon solvent mixture for injection into a subterranean formation to enhance production of viscous hydrocarbons from the subterranean formation. The hydrocarbon solvent mixture may be injected into the subterranean formation as a vapor stream with a vapor pressure. The method may include selecting a composition of the hydrocarbon solvent mixture based at least in part on a stream temperature at which the vapor stream is to be injected into the subterranean formation and a threshold maximum pressure of the subterranean formation.
