METHOD AND SYSTEM FOR ENHANCING THE RECOVERY OF HEAVY OIL FROM A RESERVOIR

The present disclosure provides a method and system for enhancing recovery of heavy oil from a reservoir that includes increasing a reservoir pore pressure, then; creating a first differential pressure, then; producing primary sweep volume; injecting an injection media into the subsurface formation,...

Zusammenfassung:The present disclosure provides a method and system for enhancing recovery of heavy oil from a reservoir that includes increasing a reservoir pore pressure, then; creating a first differential pressure, then; producing primary sweep volume; injecting an injection media into the subsurface formation, then; ceasing injecting the injection media before the injection media is produced by the at least one production well and ceasing producing primary sweep volume from the subsurface formation before the injection media is produced, then; shutting in one or more of the at least one injection well and the at least one production well; and one of recompleting one or more of the at least one production well as a recompleted injection well and recompleting one or more of the at least one injection well as a recompleted production well.
