The collapse pressure and fracture force for shale–sandstone had been computed throughout varying elastic modulus and Poisson’s ratios to find out the Harmless density window. The Patchy Aircraft of Weak point criterion extends Jaeger’s single weak plane model by in the same way dividing the failure of laminated shale https://bookmarkfame.com/story21401262/an-unbiased-view-of-rock-mechanics-in-wellbore-stability
