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 ...
