摘要
A method of stimulating coalbed methane production by injecting gas into a producer and subsequently placing die producer back on production is described. A decrease in water production may also result The increase in gas production and decrease in water production may result from: (1) die displacement of water from die producer by gas; (2) die establishment of a mobile gas saturation at an extended distance into the coalbed, extending outward from the producer; and (3) the reduction in coalbed methane partial pressure between the coal matrix and die coal's cleat system.
