摘要：

Previous investigators suggest that more than one half of the gas stored in the Devonian Shales may exist in an adsorbed state. However, adsorption is considered to be an unconventional mode of gas storage and is not often accounted for in conventional reservoir engineering analysis. This article examines the role that desorption may play in gas production from Devonian Shale reservoirs. The results suggest that accounting for gas desorption can have a significant effect on production forecasts and estimates of gas reserves. A methodology is presented for detecting the presence of gas desorption and for estimating the parameters that describe the desorption process from Devonian Shale production data. The accuracy of these parameter estimates and the effects of stimulating the desorption mechanism are also examined.
