MATHEMATICAL-MODEL OF A HOT DRY ROCK SYSTEM

We derive a mathematical model which can be used to determine the evolution of the temperature in a Hot Dry Rock system. The essential feature of this approach is given by the fact that the solution is available by analytical methods. Therefore, long-term predictions of the evolution of the temperature as well as a detailed study concerning the influence of critical parameters become available. Although this approach is based on simplifying hypotheses, it provides a good overview of the evolution of the temperature in a Hot Dry Rock system which can be used for efficiency calculations.
