Abstract: Abstract An in-depth understanding of gas transport in ultra-tight porous media is the key to quantifying flow properties of shale rocks with pore space as small as a few nanometers, where the gas rarefaction effects… read more here.

Abstract: Abstract It is a well-established fact that mineral matter in actual ultra-tight gas reservoirs presents a strong affinity for water. However, the presence of water within nanopores has not drawn due attention and is generally… read more here.

DOI: 10.1016/j.jngse.2021.104215
Abstract: Abstract Gas rarefaction phenomenon during gas flows in tight pore spaces makes the gas permeability of tight and ultra-tight rocks higher than the intrinsic permeability. Gas permeability equations in the literature usually assume a pre-defined… read more here.
