Abstract
A byproduct of intensive research conducted by the Bureau of Mines on degasification of coalbeds for improved mine safety is evidence that commercial quantities of pipeline quality natural gas can be produced. Coalbed degasification by draining gas from the coalbed before it is mined can be accomplished by drilling vertical holes into coalbeds with subsequent stimulation by hydrofracturing. By drilling horizontal holes into virgin coalbed areas from small specially designed boreholes, drainage holes from large ventilation shafts can be sunk to the coalbed in advance of mining. It is estimated that the minable coalbeds of the conterminous United States that are less than 3,000 feet deep may contain 260 trillion cubic feet of natural gas. The pertinent coalbed properties are discussed and results of a novel drilling method are presented.
