Abstract
A method is disclosed for increasing the methane recovery rate through a wellbore which penetrates a coal seam. The invention utilizes the cavitation of the coal seam surrounding the wellbore after a substantial percentage of the original methane-in-place which is available for recovery from the wellbore has been recovered from the coal seam.
