Method and apparatus for desorbing methane from coal formations via pressure waves or acoustic vibrations |
摘要 |
One embodiment of this method involves using an acoustic device (including devices that emit acoustic waves at subsonic, sonic, and ultrasonic frequencies) that induces pressure changes at high frequencies. Those pressure changes could be induced across a large area from a single device location. Thus, one acoustic device located in one wellbore can desorb gas from a large volume of coal.
