Pore Structure and Heterogeneity in Deep Coal Reservoirs: Macrolithotype Controls and Implications for CBM Development

The heterogeneity of pore structure in deep coal reservoirs is a critical factor controlling the storage and transport capacity of coalbed methane (CBM). However, the fundamental control exerted by macrolithotypes remains inadequately quantified.

Constant volume CBM reservoirs: An important principle

, 2009
Much research and many field trials have shown that the permeability of coal seams varies inversely with the effective stress acting on coal. It was later theorized by Gray (1992) that desorption-induced matrix shrinkage may counter-act the effect of ...
