... to describe shale micropores or microcracks, simply because each is fed with gas by dozens or hundreds of intricately connected nanopores, which themselves may be slits rather than circular cylinders, and are charged with the dense, liquid-like gas. In the small-scale, low-velocity flows of gases, failure...

... are characterized by their own effective uniform permeability fields; hence, they are continua for fast viscous/diffusive transport of the free gas. Micropores, on the other hand, are primary pores retaining the bulk of the gas in-place at an adsorbed state. Resistence in the micropores is due to surface diffusion...

... model in a coalbed reservoir simulator. In the bidisperse model, gas adsorption is assumed to take place only in the micropores, with the macropores providing storage for free gas, as well as tortuous paths for gas transport between the micropores and cleats.

A micropore network allows diffusion of gas desorbed from the coal matrix to enter the macropore system. The desorption process is modelled on the basis of equilibrium Langmuir isotherms and desorption rate...
