SYSTEM FOR IMPROVING COALBED GAS PRODUCTION |
摘要 |
A method of simulating coalbed (5) methane production by injecting gas into a producer (2) and subsequently placing the producer (2) 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: the displacement of water from the producer (2) by gas; the establishment of a mobile gas saturation at an extended distance into the coalbed (5), extending outward from the producer (2); and the reduction in coalbed (5) methane partial pressure between the coal matrix (11) and the coal's cleat system.
