Abstract
A method and system for enhancing petroleum production are provided, in which petroleum is displaced from a fractured formation by selectively injecting fluid into selected fractures in the formation without injecting into the other non-selected fractures. The injected fluid flows out into the fractured formation and enhances recovery from the non-selected fractures. Petroleum is selectively collected from the non-selected fractures.
