The collapse pressure and fracture tension for shale–sandstone were being computed across various elastic modulus and Poisson’s ratios to ascertain the Harmless density window. As illustrated in Figure 9, when the rock’s elastic mechanical parameters approximate isotropy, the outcome from the transversely isotropic model proven Within this examine show https://this-site77432.wikilima.com/2480909/not_known_facts_about_wellbore_stability_issues
