The collapse stress and fracture force for shale–sandstone were computed throughout various elastic modulus and Poisson’s ratios to determine the safe density window. Mechanical testing serves to be a foundational phase in figuring out rock mechanical parameters, that are important for investigating the stability of shale–sandstone horizontal wellbores.
