Abstract
It is important to develop a regional hydrogeological model to identify possible recharge and discharge areas for a sustainable use of a geothermal reservoir. The Los Humeros geothermal area is situated within five surficial watersheds and coveres an area of more than 15.000 km2. A total of 208 well and spring samples were collected between June 2017 and November 2018. The stable isotope data for this region define a regression line of δDH2O = 8.032·δ18O + 12 and indicate that groundwater is recharged by regional precipitation. At least 39 groundwater wells, with a maximum temperature of 35 °C, show temperatures above the reported mean average surface temperature of 15 °C. Characteristic elements for geothermal reservoir fluids (B, Li, As) are also present in these groundwaters, indicating a possible connection between the reservoir fluid and the local groundwater through local fracture systems. Concentration of B in these hot wells is between 150 and 35000 ppb.
Highlights
The geothermal field of Los Humeros is one of the four geothermal energy exploitation areas under the responsibility of the Federal Electricity Commission (CFE in Spanish)
As part of the GeMEX project approved at the end of 2016, different sub-projects are being carried out in this area, one of which is the development of a hydrogeological model for the Los Humeros region
The respective temperature ranges of the wells and springs of the Los Humeros region permitted a division of the samples into four groups: cold springs (63 samples), hot spring (1 samples), wells with lower than mean average air temperature (30 samples; cold wells), and wells with higher than mean average air temperature (39 samples; hot wells)
Summary
The geothermal field of Los Humeros is one of the four geothermal energy exploitation areas under the responsibility of the Federal Electricity Commission (CFE in Spanish). As part of the GeMEX project approved at the end of 2016, different sub-projects are being carried out in this area, one of which is the development of a hydrogeological model for the Los Humeros region. These studies identified the aquifers present in the different watersheds and estimated approximate water balances
