The collapse strain and fracture pressure for shale–sandstone were computed across different elastic modulus and Poisson’s ratios to find out the Protected density window. As illustrated in Determine 9, if the rock’s elastic mechanical parameters approximate isotropy, the outcomes through the transversely isotropic product recognized Within this review exhibit https://jeffreypumgu.idblogmaker.com/40434941/what-does-shale-wellbore-stability-mean
