Coupled XFEM–Fluid Pipe Element Modeling of Nonuniform Fracture Propagation in Multicluster Fracturing: A Case Study of the Shaximiao Formation, Zitong Area in China
This study investigates the challenge of imbalanced fracture propagation during multicluster hydraulic fracturing in tight sandstone reservoirs of the Zitong Shaximiao Formation. A coupled extended finite-element method (XFEM)–fluid pipe element model is developed to systematically analyze the influence of operatio...
