Principles of Geothermics: Physical basis of heat transfer: fundamental terms of heat conduction, heat conduction equations, and thermal properties of rocks. Thermal state of the earth's interior: methods of temperature determination (of uppermost crust, at great depths). Geothermal Data Acquisition: Temperature profiles from fluid injection and production wells. Processing of temperature data from borehole (wellbore) measurements. Radioactive, acoustic, radiometric & electrical well logging methods. Hydrogeology for Geothermal Energy Production: Introduction to hydrogeology and water cycle. Hydrological rock properties, water flow in porous and fractures aquifers, Darcy’s law and groundwater flow equation, groundwater modeling with MODFLOW. Introduction to hydrochemistry, water composition: major, minor and trace elements, Sampling techniques, application of tracer, water pollutants. Hydro-chemical characterization of groundwater levels. Thermodynamic fundamentals for hydro-geochemical modeling, training on the use of PHREEQC and PHAST software
