In order to determine in detail the underground temperature for the utilization of geothermal energy, researchers at the Institute for Renewable Energy (IER) of the National University of Mexico (UNAM) designed and developed software that determines the thermal diffusivity of the subsoil, i.e., how fast heat is transferred through the rocks without removing them from the ground.
This tool obtains in situ data with temperature measurements from the shaft in 36 hours. The thermal history is reconstructed from the start of drilling, during and in recovery. Various parameters can be determined such as heat flux, cementation processes, or the viability of exploiting the geothermal resources.
Dr. Jorge Wong, project leader, explained that the so-called "simulator to determine the formation diffusivity at the bottom of geothermal wells," developed since 2013, works as a start module with the polynomial rational method, patented in 2015 by its inventors.
