Study of geothermal power generation from a very deep oil well with a wellbore heat exchanger

The simulations demonstrated the importance to consider the change of fluid properties inside the exchanger. With a water flowrate of 15 m3/h the optimum condition is obtained; under such condition, the thermal power is 1.5 MW and the net electrical power is 134 kW for single well. The results lead also to conclude that the water is the best heat transfer fluid.
