... The matrix pore structure of unconventional gas reservoirs, such as tight gas and shale gas, has an important control on both hydrocarbon storage and transport yet its characterization has proven difficult. The finest pore sizes, typically associated with organic matter and clays, are often in...

For example, there can be gas present in the fracture system of a shale gas reservoir that gives short-lived, early production but the dominant gas production mechanism may be the longer-term desorption of gas from the shale and transport to the producing well. Thus, production...
