A method is disclosed for increasing the production of methane from a solid carbonaceous subterranean formation having a standard initial production rate of a methane-containing gas of X standard cubic feet per unit time. The method comprises the steps of injecting an inert methane-desorbing gas into the formation; terminating injection of the methane-desorbing gas; and thereafter recovering greater than X standard cubic feet per unit time of a methane-containing gas from the formation. In some embodiments, a number of well systems exceeding the number of available inert gas production and injection units can be operated in accordance with the present invention to yield greater methane-containing gas production than would be obtained if the available injection systems were dedicated continuously to particular well systems.

A method for increasing the production of methane from a solid carbonaceous subterranean formation having a standard initial production rate of a methane-containing gas of X standard cubic feet per unit time, where X is a positive number, said method comprising the steps of: injecting an inert methane-desorbing gas into the formation; recovering greater than X standard cubic feet per unit time of a first methane-containing gas from the formation during the injecting step; terminating injection of the methane-desorbing gas; and thereafter recovering greater than X standard cubic feet per unit time of a second methane-containing gas from the formation.
