Abstract

Sustainability Utilization of the Fault-Controlled Wentang Geothermal Field With Hydrogeological Numerical Model at Site Scale

Highlights

  • Geothermal energy is a renewable geological resource with the potential to provide a reasonable amount of electricity, heating/cooling, and balneology (Anderson and Rezaie, 2019; Soltani et al, 2021)

  • A numerical study dedicated to the prediction of the long-term sustainability of geothermal heat extraction in a fault-control geological setting while integrating site-specific information and monitoring data is of great value to both academia and industry (Meng et al, 2019)

  • The geothermal water flow is blocked by the fault structure near Wentang geothermal field (WGF) and is discharged to the surface in the form of ascending hot spring

Summary

INTRODUCTION

Geothermal energy is a renewable geological resource with the potential to provide a reasonable amount of electricity, heating/cooling, and balneology (Anderson and Rezaie, 2019; Soltani et al, 2021). The flow rate of exploited water (and thermal), which mainly depends on the local hydraulic properties of the reservoir and the model of utilization, must be lower or equal to the renewable recharge of the system (Kaczmarczyk et al, 2020). Due to the development of local tourism and health industries, the demand for hot water is increasing, which is met by drilling wellbores that exploited the thermal groundwater. The ongoing exploitation seems renewable for the utilization of the WGF geothermal resource. Even though rigorous management policies have been established in WGF for energy production, the literature is lacking detailed information on the sustainable utilization of thermal water for tourism purposes. A large amount of hot water needed cannot be extracted immediately This phenomenon is more obvious in winter with large consumption demand.
