# Example 2: Geothermal Direct-Use Example Problem using a Linear Heat Sweep Model.
# This problem considers an EGS reservoir at 3km depth.
# Ramey's model is applied to simulate production wellbore heat losses. The heat
# is used in direct-use heat application with reinjection temperature of 70deg.C
