Understanding gas adsorptions in porous media is of critical importance to numerous
academic research and industrial applications. Here, adsorptions of methane and carbon …

Although many coal permeability models have been developed in the past decades to
describe the coal permeability behaviour under elastic state, few of them address the coal …

Low velocity non-Darcy flow in shale and tight oil reservoirs is described by nonlinear or
nonhomogeneous models. These models, especially for well shut-in period, are usually …

Hydraulic fracturing enhances the recovery of gas from ultralow permeability shales, into
which water-based fracturing fluids, proppants, and activators are typically injected …

The variation of methane adsorption property of coal after the treatment of hydraulic slotting
and methane pre-drainage was investigated by testing the seven coal samples obtained …

Fractional-derivative models have been developed recently to interpret various hydrologic
dynamics, such as dissolved contaminant transport in groundwater. However, they have not …

Heat-injection into coal seam has gained great attention as a supplementary method for the
improvement of unconventional gas recovery from deep reservoirs in recent years. However …

Due to complex pore structures and ultra-low permeability in unconventional gas reservoirs,
the flow consistency between the macro-flow in fracture network and the micro-flow or gas …

Naturally fractured carbonate reservoirs have been discovered in many oilfields around the
world and are characteristic of a complex, heterogeneous porosity system. The presence of …

Borehole drainage is the most effective means of extracting coal seam gas. However,
numerous boreholes are usually needed to create strong drainage from a single coal seam …
