Thermal response geothermal testing unit

A method for performing a thermal response test to determine the thermo-physical properties of a geothermal heat exchange resource, comprising:

• providing a geothermal heat exchanger coupled with fluid in a sample borehole in the geothermal heat exchange resource;
• performing a thermal response test on the geothermal heat exchange resource, comprising:
• controlling a time-dynamic flow rate of the fluid using a variable speed pumping system, and
• applying a series of time-dynamic heat pulses via a multi-stage heating system;
• and
• collecting test data including fluid temperature and one or more of fluid pressure, fluid density and/or fluid flow rate, and determining the thermo-physical properties of the geothermal heat exchange resource.

A non-transitory computer readable medium storing computer readable program code for causing a computer to perform a process that includes the steps of:

• accessing a test procedure plan;
• performing a thermal response test based on the test procedure plan, the thermal response test including the steps of:
• controlling a time-dynamic fluid flow rate using a variable speed pumping system of a sample geothermal heat exchanger, and
• applying a series of time-dynamic heat pulses via a multi-stage heating system;
• recording measured test data from the thermal response test;
• and
• saving the measured test data to a storage medium.
