Stress effects on the relative permeabilities of tight sandstones
Comptes Rendus. Géoscience, 2018 This note deals with the study of stress-sensitive relative permeability experimentally observed in low permeable sandstones. These sandstones are made up of quartz grains surrounded by permeable interfaces between grains and pores. A micromechanical model of relative permeability behaviour under loading highlights the role of the closure of interfaces.

Seismic wave equations in tight oil/gas sandstone media [PDF]
Science China Earth Sciences, 2020 The paper is devoted to the derivation of a combined system of motion equations for solid and fluid in isotropic tight oil/gas sandstone media through volume averaging theorems (VAT). Based on the features of the media, four physical assumptions are proposed as the foundation for our derivation.
