1. A method for separating and recovering methane and other similar fuel components from the liquids in underground fluid zones that exist naturally at high pressures comprising the steps of:
- (a) incorporating a gas permeable membrane selective for the methane and other similar fuel components into a gas collection system;
(b) subjecting said membrane to the liquid containing the methane and other similar fuel components;
(c) permeating the methane and other similar fuel components through said membrane; and
(d) collecting the permeated methane and other similar fuel components while rejecting the liquid.

Abstract
In accordance with the method of the present invention, methane and other similar fuel components are separated from the brine found in geopressurized geothermal zones by immersing gas permeable membranes selective for these fuel components into the brine in these zones, and permitting these fuel components to permeate through the membranes while rejecting the brine. The permeated fuel components then are collected.
