Abstract
Natural gas can be produced from coalbeds by drilling holes from the surface into the coalbed. These holes are not like ordinary gas wells because the coalbed is not like an ordinary sandstone reservoir, nor is it like a shale reservoir. Gas is held in coalbeds mainly by sorption and the coalbeds that contain large quantities of gas are water-saturated. In developing the flow characteristics of a coalbed for gas production, a two-phase system must be considered--namely, gas and water. The Bureau of Mines has developed methods for routinely determining the gas content of coalbeds and as a larger data base is established, it will be possible to estimate accurately the gas that can be recovered from United States coalbeds.
