Abstract: Abstract Modelling wettability of tight rocks is challenging due to their complex pore networks, sub-micron pore throats, and organic pores. The experimental results show oil-wet behavior of dry core plugs. Assuming different flow paths for… read more here.

DOI: 10.1016/j.fuel.2020.118974
Abstract: Abstract Adsorbed-phase surface diffusion has been recognized as an important controlling factor on gas apparent permeability in micropores and smaller mesopores. However, for the estimation of surface diffusion coefficients of shales, the commonly used empirical… read more here.

DOI: 10.1021/acs.energyfuels.0c02160
Abstract: Recent studies show that oil production from unconventional tight rocks is inefficient since the oil is mainly trapped in their submicron hydrophobic pores. Different types of surfactants have been... read more here.
