Abstract:
A method of natural gas production from wells drilled into geopressured aquifers containing methane saturated water, comprising using wells which permit initial flow of water with a complete absence of back pressure at the well head, and containing the flow of water until loss of pressure in the aquifer exsolves sufficient gas to reverse the gas/water permeability ratio, thus converting the flow entirely to natural gas and water vapor and creating a gas cap. A further embodiment is the subsequent use of rings of secondary wells of similar design, each ring located at approximately equal radial distances from the initial well, to produce similar gas caps which interact with-, and produce from-, the gas cap created by production from the initial well and the gas caps of the other secondary wells.
