As the particularly popular green energy, geothermal resources are gradually favored by countries around the world, and the development model centered on geothermal dew point cannot meet the increasing geothermal demand. In this paper, a GIS model combining PCA and AHP is proposed, aiming to select the advantages of geothermal resources at the regional scale and analyze the main influencing indicators. Through the combination of the two methods, both data and empirical can be considered, then the geothermal advantage distribution on the area can be displayed through GIS software images. A multi-index evaluation system is established to qualitatively and quantitatively evaluate the mid-high temperature geothermal resources in Jiangxi Province, and carry out the evaluation of the dominant target areas and the analysis of geothermal impact indicators. The results show that it is divided into 7 geothermal resource potential areas and 38 geothermal advantage targets, and the determination of deep fault is the most critical index of geothermal distribution. This method is suitable for large-scale geothermal research, multi-index and multi-data model analysis and precise positioning of high-quality geothermal resource targets, which can meet the needs of geothermal research at the regional scale.

Jiangxi Province is located in the tropical zone of mid-high temperature geothermal resources along the southeastern coast of China. Geothermal geological surveys, the exposed natural hot springs, the explored geothermal walls and the reported geothermal research results related to the potential of geothermal energy indicate the abundant geothermal resources and the high formation potential of mid-high temperature geothermal resources in Jiangxi Province. However, the research level of geothermal resources in this area is relatively low, the distribution of geothermal hotspots is uneven, and the specific resource distribution, geothermal temperature, and resource quantity are not well understood, so it is difficult to systematically carry out the mid-high geothermal development in this province. Therefore, we collect the data of the study area, established a multi-index evaluation model combining experience and data, and carried out the evaluation of geothermal resources advantageous target areas and the analysis of geothermal impact indicators. The main purpose of this study is to use analytic hierarchy process (AHP) and principal component analysis (PCA) to qualitatively and quantitatively evaluate the mid-high temperature geothermal resources of the Jiangxi Province, and also to propose a dual-method comparative evaluation model for the study of the mid-high geothermal target area. Based on the quantitative data from geological, hydrological and geophysical sources and the extensive experience of regional workers and geologists, by using the AHP and PCA, we divide the study area into 7 geothermal resource potential zones and 38 geothermal optimal target areas. It is determined that deep large faults are the most critical indicators affecting the distribution of geothermal resources in the study area, followed by the heat storage value of the silicon enthalpy equation and the magmatic rocks. This study is of great significance for geothermal research in similar areas, multi-index and multi-data model analysis, and accurate positioning of high-quality geothermal resource target areas. It also has important guiding significance for the follow-up development planning of geothermal resources the research area or further research on the geothermal target area.

“…Local examples of conduction-dominated systems include the pilot project by Parex Resources in Casanare's Las Maracas and Rumba fields, undergoing assessments to enhance conductiondominated and low-entalphy geothermal resources are being performed in the Llanos Basin [López-Ramos et al, 2022]. Similar studies are underway internationally, such as in China, where the feasibility of using abandoned oil and gas wells for energy is being assessed [Bu et al, 2012], and in Uruguay, where the geothermal potential of sedimentary onshore basins is explored [Morales et al, 2021].…”

The Aguas de Vichy thermal spring (SAN-001), identified by the Colombian Geological Service (SGC) and located in Santander, Colombia, represents a significant yet underexplored geothermal resource. This study is the first to conduct subsurface imaging of the geothermal system, employing Electrical Resistivity Tomography (ERT) and Induced Polarization (IP) methods to investigate the hydrogeological framework. Geochemical analyses of the spring water indicate high salinity and elevated temperatures, suggesting a substantial energy capacity. The geological setting is characterized by north-south (N-S) and northeast-southwest (NE-SW) faults, intersecting Cretaceous and Precambrian formations, along with a Quaternary aquifer. Three ERT transects were conducted around the inferred fault, which was hypothesized to be the main conduit for geothermal fluids. Two transects crossing the fault revealed resistivity values ranging from near zero to over 1500 ohm-meters, suggesting the presence of zones of clay, groundwater accumulation, and geothermal fluids. High resistivity anomalies at depths of 5 to 10 meters indicate the lower boundaries of the Quaternary deposits. The third transect, situated within the Quaternary deposit but distant from the fault, exhibited elevated resistivities and a diminished prevalence of anomalies, indicating a possible clay deposit with reduced influence of water. IP measurements validated the presence of geothermal fluids and illuminated areas with elevated chargeability, suggesting the presence of clay levels within the aquifer. Our findings support the existence of a geothermal system where convection plays a significant role, alongside notable advective movements within the aquifer. This suggests a complex interaction of subsurface fluid dynamics, integrating both fault-mediated fluid transport and advection processes rather than being solely advection-dominated as suggested initially. The complexity observed in these findings underscores the necessity for further detailed studies to enhance our understanding of the geothermal system's dynamics and potential, which could make a valuable contribution to Colombia’s energy sustainability objectives.
