Abstract: Abstract Experimental measurements of shale permeability are normally conducted under conditions of constant effective stresses. Based on the theory of poroelasticity, shale permeability in non-sorbing media is determined by the effective stress alone and remains… read more here.

Abstract: The effects of temperature on the permeability coefficients of carbonaceous shales and the underlying mechanisms have been investigated experimentally. Pressure-pulse-decay gas-permeability tests were performed on seven shale plugs with different lithological compositions, organic-matter contents ranging… read more here.
