Lithology-Dependent Fracture Propagation in Ultra-Large True-Triaxial Hydraulic-Fracturing Experiments
Tight reservoirs commonly exhibit low permeability and pronounced lithological heterogeneity, resulting in complex interactions among far-field stress, local structural weakness, and fluid-driven fracture propagation. In this study, four non-replicated 2 m × 2 m × 1 m physical-model specimens representing tight gluteni...
