The collapse stress and fracture strain for shale–sandstone were computed throughout varying elastic modulus and Poisson’s ratios to determine the Harmless density window. Assuming horizontal bedding in the formation and thinking about the impact of bedding planes, the variation of wellbore collapse strain polar plots with formation drilling time https://israelgfbrk.dm-blog.com/42953446/an-unbiased-view-of-rock-mechanics-in-wellbore-stability
