... Abstract The exploitation of shale gas has attracted extensive attention in industry and academia. Multi-scale gas transportation mechanisms in matrix and fractures have been well studied. However, due to the presence of water originating from both fracking fluids and connate water, shale gas...

... that a reservoir depth is generally 500 ~ 3,000 m and the reservoir pressure is 5 ~ 30 MPa in shale gas reservoirs in North America ( Curtis 2002 ). Furthermore, in China, a reservoir depth is generally 3,000 ~ 6,000 m with up to 60MPa of a reservoir pressure ( Wang et al. 2011 ). Gas transport mechanisms in shale...

... at walls, is only valid within continuum regime. However, the Knudsen number K n in most shale reservoirs lies between 10 −3 to 1 ( Ziarani, 2011 ), which indicates that the slip and transition flow regimes are most likely to be encountered in most shale gas reservoirs. The apparent permeability...

In nanopores, as encountered in tight shale gas reservoirs, the effects of diffusion can overcome advection and should be included in reservoir flow calculations. As the permeability of shale is very low, conventional reservoir...

... A sharp initial decline in the production rate is being experienced in many shale gas plays. One reason is the closure of natural micron and micro fractures. The natural fractures, which widely exist in the over-pressurized source rock, react sensitively to the change of subsurface stress. The change...

... Natural gas in shale gas formations is present both as a free gas phase and as adsorbed gas on solids in pores. In these reservoirs, gas or methane molecules are adsorbed mainly to the carbon-rich components, i.e. kerogen ( Silin and Kneafsey, 2011 ; Mengal and Wattenbarger, 2011 ; EIA, 2011...
