Stage-Dependent Responses in Sequential Dual-Well Supercritical CO2 Fracturing: A Sparse Second-Order Choquet Fracability Framework with Monte Carlo Uncertainty

Deep tight-reservoir fracability depends on temperature, fluid transport, in situ stress, fracture development, and injection energy, so no single response can provide a defensible ranking of fracturing conditions. This study develops a sparse second-order Choquet–Monte Carlo fracability framework. Additionally, the CR...

Experimental Study of Supercritical CO2 Dual-Well Fracturing under the Effects of High Temperatures and In Situ Stress Differentials

Supercritical CO2 (SC–CO2) dual-well fracturing is a key technology for the development of deep tight reservoirs, where fracture propagation is predominantly influenced by the coupled effects of high temperature and in situ stress. To address the lack of systematic experimental investigations under high-temperature c...

A Porosity-Dependent Constitutive Model for Concrete Under Wetting–Drying Cycles: Experimental and Field Validation

The degradation of concrete under wetting–drying cycles significantly compromises the safety and durability of bridge structures; however, existing constitutive models often exhibit limitations in practical engineering applicability. To improve the engineering applicability of existing constitutive models, this study p...
