  • Patent number: 5014788
    Abstract: A method of increasing the rate of methane production from a coal seam includes introducing a desired volume of a gas, that causes coal to swell, into the coal seam adjacent a wellbore, maintaining the coal seam adjacent the wellbore in a pressurized condition for a period of time to permit the gas to contact a desired area of the coal adjacent the wellbore, and relieving the pressure within the coal seam by permitting fluids to flow out from the wellbore at a rate essentially equivalent to the maximum rate permitted by the wellbore and any surface wellbore flow control equipment. Uneven stress fractures should be created in the coal by this method which will increase the near wellbore permeability of the coal seam.
