A rock brittleness evaluation method in interbedded reservoirs based on statistical damage constitutive

Abstract The significant heterogeneity of sandstone and mudstone interbedded reservoirs complicates the accurate evaluation of formation brittleness, thereby affecting the optimization of fracturing stage design. This paper first derives a statistical damage constitutive model to predict rock stress...
