The collapse pressure and fracture force for shale–sandstone had been computed across varying elastic modulus and Poisson’s ratios to find out the Secure density window. The PPW criterion far better reveals the strength of shale with different bedding angles. In this examine, the JPW and PPW standards are applied https://holdennjfzu.wikinarration.com/7744011/the_ultimate_guide_to_wellbore_breakout_analysis
