Geothermal reservoir potential of volcaniclastic settings: the Valley of Mexico, Central Mexico

摘要: Abstract The geothermal potential of the Valley Mexico has not been addressed in past, although volcaniclastic settings other parts world contain promising target reservoir formations. An outcrop analogue study thermophysical rock properties Neogene rocks within was conducted to assess this area. Permeability and thermal conductivity are key parameters characterization values gained from samples serve as a sufficient database for further assessment. mainly low permeable lithofacies types may be operated stimulated systems, depending on fracture porosity deeper subsurface. In some areas also auto-convective water circulation might expected direct heat use without artificial stimulation becomes reasonable. Thermophysical tuffs siliciclastic qualify them horizons future utilization deep reservoirs.
