The collapse force and fracture stress for shale–sandstone were computed throughout different elastic modulus and Poisson’s ratios to ascertain the Harmless density window. Lamellar shale oil reservoirs develop millimeter-to-centimeter-scale siltstone and mud shale complexes with lamellar constructions, that are the main growth targets soon after 2030.
