This present work reports on the heat losses associated with the upward flow of hot air, water, and CO2 in a production well. The heat losses considered here are the frictional heat loss, the gravitational heat loss, the Joule-Thomson effect, and the conduction heat loss to the surrounding rock formation. These heat losses were characterized using the mass flow rate, the operation time as variable parameters while the surrounding formation was assumed to have constant properties with a linear geothermal ...
