Method of improving recovery from hydrocarbon reservoirs

A method of increasing the recovery of hydrocarbons from a highly fractured or carbonate reservoir using the steps of injecting into the reservoir a membrane-forming fluid to form a semipermeable membrane over the surface of at least part of an exposed formation, injecting into the reservoir a fluid...

Beschreibung
Zusammenfassung:	A method of increasing the recovery of hydrocarbons from a highly fractured or carbonate reservoir using the steps of injecting into the reservoir a membrane-forming fluid to form a semipermeable membrane over the surface of at least part of an exposed formation, injecting into the reservoir a fluid to establish a chemical potential gradient across the membrane and letting fluid enter the formation across the membrane to increase the pressure inside the formation and to force additional hydrocarbon from the formation.
