The collapse stress and fracture force for shale–sandstone ended up computed throughout different elastic modulus and Poisson’s ratios to find out the safe density window. As illustrated in Figure 9, in the event the rock’s elastic mechanical parameters approximate isotropy, the results in the transversely isotropic model founded On https://bookmarkdistrict.com/story21284993/an-unbiased-view-of-shale-wellbore-stability
