Abstract
A method of increasing the recovery of hydrocarbons from a highly fractured reservoir uses the steps of injecting into the reservoir a membrane-forming fluid to form a membrane over the surface of at least part of 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.
