A method is provided for substantially self-powering turbines by expanding compressed gases released downhole or in adjacent formations. These gases do work in the turbines as the gases expand toward atmospheric pressure at the earth\s surface. The method offers alternative and supplemental approaches to recovering hydrocarbon gases, water vapor, carbon dioxide, other gases, and petroleum from watered out wells and from deep or hot wells.

A substantially self-powered method of recovering watered out natural gas comprising: (a) providing at least one well into at least one formation containing the said watered out natural gas such that fluids from the said formation can flow into the said well, (b) emplacing at least one centrifugal turbine in the said well, (c) providing at least one conduit through which gas substantially at or below formation pressures can flow from the said centrifugal turbine to lower pressures substantially at the earth\s surface, (d) providing at least one additional conduit through which liquids can flow to be discharged, (e) providing means for substantially separating natural gas and brine, (f) flowing fluid from the said formation and to the said centrifugal turbine in the said well, (g) expanding the said fluid in the said centrifugal turbine, thereby providing self-powering, (h) separating the said expanded fluid into released natural gas and spent brine, (i) flowing the said released natural gas from the well, through the said one conduit and substantially to the earth\s surface, (j) flowing the said spent brine from the said well and through the said additional conduit means to discharge, and (k) allowing brine circulation in formations adjacent to the well corollary to brine flow into and out of the well.
