Seismic Wave Equations in Tight Oil/Gas Sandstone Media [PDF]
Science China Earth Sciences, 2018 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.

Matrix gas flow through ‘impermeable’ rocks – shales and tight sandstone [PDF]
Solid Earth, 2021 Abstract. The effective pressure sensitivity of gas flow through two shales (Bowland and Haynesville shales) and a tight gas sandstone (Pennant sandstone) was measured over the typical range of reservoir pressure conditions. These are low permeability rocks such as can be exploited as caprocks above reservoirs that might be developed to store ...
