Paper presented at the SPE/IATMI Asia Pacific Oil & Gas Conference and Exhibition, October 10–12, 2023
Paper Number: SPE-215314-MS
... Abstract An advanced numerical simulation method was developed to accurately characterize the heterogeneous geomechanical damage of heterogeneous matrix, hydraulic fractures, and natural fractures during production. The proposed model can automatically obtain the geomechanical damage correction...
