... derived from core samples, well logs, and seismic data, are often insufficient for dynamic reservoir conditions where fracture behavior is influenced by changing stress, fluid interactions, and geological factors (Gale et al., 2014; Bostrom et al., 2014; Gong et al., 2023). These limitations can lead...
