The collapse tension and fracture stress for shale–sandstone have been computed throughout different elastic modulus and Poisson’s ratios to ascertain the safe density window. As illustrated in Determine nine, when the rock’s elastic mechanical parameters approximate isotropy, the final results with the transversely isotropic model proven Within this analyze https://jaredonfzr.thecomputerwiki.com/6674609/the_5_second_trick_for_wellbore_stability_in_drilling
