Method of coalbed methane production
Patent
·
OSTI ID:7182393
This patent describes a method for producing coalbed methane from a coal seam containing coalbed methane and penetrated by at least one injection well and at least one producing well. It comprises: injecting an inert gas through the injection well and into the coal seam. The inert gas being a gas that does not react with the coal under conditions of use and that does not significantly adsorb to the coal; and producing a gas from the production well which consists essentially of the inert gas, coalbed methane, or mixtures thereof.
