The collapse tension and fracture strain for shale–sandstone were computed across different elastic modulus and Poisson’s ratios to determine the Risk-free density window. To obtain the wellbore strain, it's important to ascertain the conversion partnership concerning the geodetic coordinates along with the strain coordinates, the wellbore orthogonal polar coordinates, https://sergiotyunt.plpwiki.com/7693192/an_unbiased_view_of_shale_wellbore_stability
