The collapse pressure and fracture strain for shale–sandstone have been computed across different elastic modulus and Poisson’s ratios to determine the safe density window. Mechanical testing serves as being a foundational step in analyzing rock mechanical parameters, which might be important for investigating the stability of shale–sandstone horizontal wellbores. https://vertechs.mystrikingly.com/blog/advancing-well-control-how-vertechs-is-shaping-the-future-of-safe-drilling
