Abstract

A method for increasing the production of methane from a subterranean coal formation by chemically stimulating the formation of cleats in the coal formation in order to facilitate removal of formation water, and increase the rate of methaneproduction from the coal formation.

The method comprises injecting an aqueous oxidant solution into the coal formations to stimulate the formation of cleats in the coal formation; and thereafter producing methane from the coal formations at an increased rate. The aqueous oxidant solution preferably comprises hypochlorite, metaic salts of hypochlorous acid, hydrogen peroxide, ozone, oxygen and combinations thereof.
