Vertical Propagation Behavior of Hydraulic Fractures and Fracability Evaluation in Shale Reservoirs: A Case Study of the Yongchuan Block, Sichuan Basin
Vertical hydraulic-fracture propagation controls the effective stimulated thickness of deep layered shale, yet conventional fracability indices omit this response. Coupled hydromechanical cohesive-zone models were built for nine sublayers in the northern and southern Yongchuan sub-blocks, Sichuan Basin, using rock-mech...
