“…In 2018, Moreno et al [21] performed 2D modeling of groundwater flow and heat transfer in a fractured geothermal reservoir in the northwestern area of the NRV. This work concludes and validates that secondary permeability, represented mainly by local and regional geological faults, behaves as a natural conduit that connects the surface with deep geological environments, and it is responsible for the hydrothermal activity observed on the surface.…”

Colombia is a country with great potential for the exploitation of geothermal energy due to its high volcanic activity caused by the subduction between the Nazca and South American tectonic plates. However, this energy is yet to be exploited. This article seeks to describe, by means of a literature review and information processing, the current status of geothermal energy in Colombia, including the current regulations, the limitations, the recommendations to develop the geothermal energy, and some of the most important projects, studies, and research papers that have been emerged on the discovery, exploration, and exploitation of geothermal energy within the country, emphasizing the areas where exploration projects have been initiated, such as the Nevado del Ruiz volcano, the Tufiño–Chiles–Cerro Negro volcanic system, the Azufral volcano geothermal area, and the Paipa geothermal area. Over the years, energy vulnerability in Colombia and a government policy of fostering sustainable development in different territories have generated favorable conditions for the exploitation of geothermal resources. Nevertheless, there are several technical, infrastructural, legal, and institutional barriers that slow the proper development of these projects.

“…The high bicarbonate, low chloride composition indicates that thermal fluids have mixed with cooler groundwater or meteoric water as it circulates in upwelling zones along faults (Truesdell 1975). Due to the highly fractured and faulted crustal structures hosting the geothermal systems in Madagascar, there is considerable potential for meteoric water to infiltrate into deeper aquifers and for groundwater to ascend along faults, depending on their dip directions (Reed 1983;Moreno et al 2018). This is why faults have been assumed to be flow paths in our conceptual models for all six Madagascar geothermal areas (Figs.…”

“…The hot springs in the prospective areas of Madagascar are usually located near faults, and the fluid flow appears controlled by tectonic structures. The temperature of the hot springs is likely to decrease at the end of their flow path before reaching the surface, as a result of dilution with cold superficial waters and conduction-convection heat processes (Reed 1983;Ferguson et al 2009;Moreno et al 2018). The fluids of geothermal systems in Madagascar are thus related to the deep circulation of meteoric water along faults and fractures, similar to the geothermal systems of the Basin and Range Province where there is no active magmatism (Muffler 1975).…”

The first investigation into the geothermal potential of Madagascar was compiling an inventory of the hot springs (Besairie 1959), which was followed two decades later by an assessment of the geochemical characteristics of geothermal energy sources using chemical and isotopic analysis and chemical geothermometers on samples of hot spring water (Gunnlaugsson et al. 1981). The results provided a general characterization of the geothermal regions of Madagascar (Andrianaivo 2011). The prospective areas in this study have been subject to geological assessments, including structural geology (Andrianaivo and Ramasiarinoro 2010a, b). Knowing that geothermal exploration in Madagascar is at an early stage and that there is currently no geothermal power production in the country, this study reviews the available results from previous work with the objective to better understand the factors affecting the geothermal energy source and to produce the first catalogue of geothermal systems in Madagascar. The aim of the classification is to highlight the dominant characteristics of each area.

“…In Chile, students from PhD to undergraduate level have been involved in geothermal and hydrogeology research in fractured geological media at the CEGA and they presented their results and ongoing work during the IGCP636 2017 Annual Meeting. Main areas of interests are Baños Morales and Baños Colina hot springs (Anselmo et al, 2017), the Aysen region (Negri et al, 2018), Pica thermal spring area (Placencia-Marin et al, 2017), the Aconcagua Basin (Taucare et al, 2017), and the El Tatio Geyser Field (Slagter et al, 2017).…”

Geothermal fluids are extracted through deep wells drilled in a geological reservoir, which can be represented by highly heterogeneous volcanic complex, sedimentary basins or deep basement rocks. The main objective of this project was to propose suitable methodologies and techniques for the characterization and modeling of fractured geothermal reservoirs, to ensure their sustainable exploitation and, therefore, ensure acceptation of this kind of energy by local communities. This goal was achieved with experiences from the volcanic complex of the Nevado del Ruiz (Colombia), the St. Lawrence Lowlands sedimentary basin (Québec, Canada), the Carboniferous limestone reservoir in the area of Mons (Belgium), the Soultz-Sous-Forêts power plant and the Ploemeur fractured rock hydrogeological experimental site (France), and various areas of interest for geothermal exploration in Chile. The work conducted provided new insights into the construction of conceptual and numerical models for geothermal reservoirs and allowed the creation of a solid research network between Europe and Americas, fostering participation in geosciences of young researchers, students, and women.
