Summary:THE INVENTION IS A METHOD AND SYSTEM OF SEPARATING A MULTI-COMPONENT FLUID IN A WELLBORE (1O). AT LEAST ONE FLUID SEPARATION MEMBRANE (21) COMPRISING A FEED SIDE AND A PERMEATE SIDE IS INCORPORATED IN THE WELLBORE. A FLOWING STREAM OF THE MULTI- COMPONENT FLUID OBTAINED FROM A SUBTERRANEAN ZONE BEING IN FLUID COMMUNICATION WITH THE WELLBORE (10) IS PASSED ACROSS THE FEED SIDE OF THE MEMBRANE AT A FIRST PRESSURE. A RETENTATE STREAM DEPLETED IN AT LEAST ONE COMPONENT COMPARED TO THE MULTI-COMPONENT FLUID IS WITHDRAWN FROM THE FEED SIDE OF THE MEMBRANE AND PASSED TO THE EARTH'S SURFACE. A PERMEATE STREAM AT A SECOND PRESSURE IS WITHDRAWN FROM THE PERMEATE SIDE, IN WHICH THE PERMEATE STREAM IS ENRICHED IN AT LEAST ONE COMPONENT COMPARED WITH THE MULTI-COMPONENT FLUID. THE SECOND PRESSURE IS CONTROLLED TO MAINTAIN THE SECOND PRESSURE BELOW THE FIRST PRESSURE. (FIG. 1)
