ELECTROMAGNETIC COAL SEAM GAS RECOVERY SYSTEM |
摘要 |
A system for recovering gas trapped within the earth includes a casing (24) sized and configured to be positioned within a borehole in the earth, the casing (24) formed of a material that is transmissive to electromagnetic energy and gas within the earth; an antenna (40) sized and configured to be positioned within the casing (24). The antenna (40) has a distal end and a proximal end and including a radiating element at the distal end of the antenna (40) which, in operation, transmits electromagnetic energy toward a desired area of the earth, and an interior channel for allowing gas to be conveyed from the distal end to the proximal end of the antenna (40).
