Example X Description: This example problem considers a simple reservoir
8+
at 2 km depth with an initial production temperature of 145deg.C. The thermal drawdown
9+
is assumed linear at 0.5%/year. The heat is converted to electricity with a subcritical
10+
ORC. It is accessed by a closed loop well.
