The collapse pressure and fracture tension for shale–sandstone were being computed across varying elastic modulus and Poisson’s ratios to ascertain the safe density window. Lamellar shale oil reservoirs acquire millimeter-to-centimeter-scale siltstone and mud shale complexes with lamellar constructions, which are the main development targets immediately after 2030.
