Increasing media permeability with acoustic vibrations

A method of methane production in a coalbed, comprising:

• drilling a borehole into a coalbed deposit with adsorbed natural gas;
• disposing within said borehole at least one sonic acoustical radiator;
• and
• operating said sonic acoustical radiators to generate sound waves which vibrate the inside faces of said borehole and the immediate adjacent coalbed media;
• wherein, said vibrations increase the permeability of said inside faces of said borehole and the immediate adjacent coalbed media and result in an increase in the exhaust of natural gas from said coalbed.

A system for increasing the material removal flowrates of hydrocarbon gases or liquids from porous and fractured media in underground deposits, comprising:

• an exhaust well borehole drilled into an underground deposit, wherein drilling has been completed;
• a drillstring pipe for disposal in the exhaust well borehole after drilling is complete, and providing for the extraction of hydrocarbon gases or liquids from any porous and fractured media surrounding the exhaust well borehole;
• an acoustic radiator mounted on the drillstring pipe such that when the drillstring pipe is disposed in the exhaust well borehole, the first acoustic radiator will be positioned proximate to expected deposits of said hydrocarbon gases or liquids in said porous and fractured media surrounding the exhaust well borehole;
• a hydraulic or pneumatic flow that is forced down the pipe during operation to power a whistling of the acoustic radiator;
• wherein, whistle vibrations coupled into said media which cause the permeability of the porous and fractured media surrounding the exhaust well borehole to be increased such that said hydrocarbon gases or liquids flow more readily into the drillstring pipe from said underground deposit.
