2:30 PM – 2:50 PM: Modeling and Simulating a Geothermal Closed-Loop System with Aspen METTE™

Geothermal energy production may be achieved through a variety of system configurations. In the closed-loop system, the fluid circulates into a sealed system contained entirely within a cased or sealed borehole. The circulation fluid, initially injected at a lower temperature, extracts heat from the rock formation inside the wells, with the cementing and pipe walls serving as resistance for the heat transfer mechanism. Aspen METTE simulates the entire thermodynamic heat transfer process along the closed-loop system. The simulation accounts for the heat coming from the rock, the resistance created by the cementing and pipe layers, and the fluid interactions. In a pipe-in-pipe layout, the interactions between annulus and tubing are also considered. By considering elements like heat transfer, fluid phase transitions, pressure differentials, and temperature profiles, Aspen METTE enables users to take into account heat produced for diverse operational scenarios. Equipment such as compressors, pumps, valves, and heat exchangers can also be included in the simulations, providing a realistic reproduction of the system. Thus, Aspen METTE serves as a valuable tool for comprehending the complex dynamics inherent in closed-loop geothermal setups, unlocking their potential as a sustainable and efficient energy source.
