In the Los Humeros geothermal field, temperatures higher than 400C have been found, being a suitable case study of a super-hot system. In Acoculco area, there are two exploratory holes with temperature of 300C at 2000m depth with practically null permeability. Hence, representing an interesting case to develop an Enhanced Geothermal System (EGS). Both areas were study subjects in the project “Mexico-Europe Cooperation to investigate improved geothermal systems and super-hot geothermal systems” (GEMex). We conduct magnetotelluric (MT) surveys in both areas to provide information on the electrical resistivity distribution at depth. We measured 123 MT sites in Los Humeros and 68 in Acoculco. The observation sites were distributed with a high spatial density to provide well-constrained resistivity models. The models clearly detect a conductive zone between 500 and 1000m deep associated with a clay zone of hydrothermal alteration. In Los Humeros the clay-cap overlies an intermediate resistivity zone probably related to the reservoir. At Acoculco, the resistivity increases rapidly beneath the clay-cap, in agreement with the presence of impermeable metamorphic rocks.","PeriodicalId":147283,"journal":{"name":"First EAGE Workshop on Geothermal Energy in Latin America","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114432938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This investigation evaluates the possibility of implementing a SWSHP system to cool at 3°C a preservation room for exportation flowers in La Virginia S.A.S located in La Ceja, at 41 km to the southeast of Medellin (Antioquia, Colombia). The temperature of two reservoirs belonging to the flower farm was monitored to analyze their potential as heat sinks for a SWSHP. The traditional and geothermal refrigeration systems were compared using empirical formulas based on the theoretical performance proposed by Carnot. It was found that the water temperature had a very little variation with respect to the ambient air temperature. The feasibility of using a surface water body as a heat sink of a SWSHP was evaluated. The coupling with other geothermal arrangements such as vertical and/or horizontal Ground Source Heat Pumps (GSHP) and even combining aerothermal is suggested.","PeriodicalId":147283,"journal":{"name":"First EAGE Workshop on Geothermal Energy in Latin America","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114168128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its fundamental base lays in the injection of electrical current through a transmitter square loop laid on the ground which induces a magnetic field that travels through the ground layers. Measurements of the resulting magnetic field are made in a receiving coil in the center of the loop since this is related to the resistivity of the ground rock layers. Due to its easy deployment, low electromagnetic noise susceptibility, and low-cost TDEM is used to monitor the shallow resistivity instead of other techniques. Since the prospection depths are not higher than 1000 m, TDEM is used to monitor the resistivity variations caused by the changes in the chemistry of the rock due to the interaction of geothermal fluid. This way, monitor a geothermal field becomes necessary to anticipate problems that could affect the supply of fluid from the reservoir or endanger the geothermal powerhouse, surrounding buildings, or houses inside the geothermal area as a result of the loss of the mechanical strength.","PeriodicalId":147283,"journal":{"name":"First EAGE Workshop on Geothermal Energy in Latin America","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115281798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
