Shales typically possess ultra-low permeabilities (usually below 1 μD) with very complex micro-structure, and is mainly composed of quartz, carbonates, clays, and organic matter (Zoback and Kohli, 2019).

Despite its significant industrial use, the method has several fallacies which include noninclusion of inelastic time-dependent effects and horizontal stresses accumulating from tectonic processes (Sone and Zoback, 2014a, 2014b; Yang et al., 2015) when describing present day stress...

Therefore...
