摘要： Enhanced methods for recovering viscous hydrocarbons from a subterranean formation as a follow-up to thermal recovery processes. The methods include injecting a solvent flood vapor stream into a first thermal chamber, which extends within the subterranean formation, via a solvent flood injection well that extends within the first thermal chamber. The injecting includes injecting to generate solvent flood-mobilized viscous hydrocarbons within the subterranean formation. The methods also include, at least partially concurrently with the injecting, producing the solvent flood-mobilized viscous hydrocarbons from a second thermal chamber, which extends within the subterranean formation, via a solvent flood production well that extends within the second thermal chamber. The first thermal chamber was formed via a first thermal recovery process, and the second thermal chamber was formed via a second thermal recovery process, and the first thermal chamber and the second thermal chamber are in fluid communication with one another.

摘要： The present disclosure relates to production of a bitumen product from a subterranean reservoir with improved processes for solvent recovery at end of production or near end of production (i.e., “late life”) of heavy oil from a solvent-based heavy oil extraction process. The process include converting at least some of the wells in the subterranean reservoir, and injecting gas phase dilution agent into the reservoir, converting at least a portion of the liquid solvent to a gas phase, and recovering, in the vapor phase, at least a portion of the solvent remaining in the reservoir.

摘要： The present invention relates generally to in situ hydrate control during hydrocarbon production when applying a recovery method utilizing cyclic injection of light hydrocarbon solvents. Hydrate formation is limited by creating an energy reserve within a hydrocarbon reservoir adjacent to the wellbore. A heated solvent is injected during an injection phase of a cyclic solvent dominated recovery process to form a heated region adjacent to the wellbore at the end of an injection cycle. The energy reserve is used to act against the evaporative cooling effect caused by subsequent production and associated depressurization to maintain reservoir conditions outside of hydrate formation conditions. In situ conditions are estimated and injected energy amounts are controlled.

摘要： Methods and apparatus for recovering heavy oil from subterranean reservoirs. A steam-utilizing heavy oil recovery process may be used to recover the heavy oil while employing a steam-solvent mixture. The solvent may be a tailored hydrocarbon solvent obtained from a precursor mixture of hydrocarbon compounds from which light end hydrocarbon compounds have been removed.

摘要： Systems and methods for enhancing production of viscous hydrocarbons from a subterranean formation. The methods may include heating a hydrocarbon solvent mixture to generate a vapor stream, injecting the vapor stream into the subterranean formation to generate reduced-viscosity hydrocarbons, and producing the reduced-viscosity hydrocarbons from the subterranean formation. The methods also may include selecting a composition of the hydrocarbon solvent mixture by determining a threshold maximum pressure of the subterranean formation, determining a stream temperature at which the vapor stream is to be injected into the subterranean formation, and selecting the composition of the hydrocarbon solvent mixture based upon the stream temperature and the threshold maximum pressure. The systems may include a hydrocarbon production system that may be configured to perform the methods and/or that may include an injection well, an injectant supply assembly, and a production well.

摘要： Thermal recovery methods for recovering viscous hydrocarbons from a subterranean formation. The thermal recovery methods include performing a plurality of injection cycles. Each injection cycle in the plurality of injection cycles includes injecting a heated solvent vapor stream into a heated chamber that extends within the subterranean formation and fluidly contacting the viscous hydrocarbons with the heated solvent vapor stream to generate mobilized viscous hydrocarbons. Each injection cycle also includes injecting a steam stream into the heated chamber. The thermal recovery methods further include producing a chamber liquid and/or mobilized viscous hydrocarbons from the subterranean formation.
