On larger projects a conductivity test is important. WHY? Ground formations vary, conductivity tests show what that ground will store for energy.
If the test shows the ground will store less energy, the geothermal field must be enlarged. If the test shows the ground will store more energy, the geothermal field may be reduced.
Here are the 3 basic steps of a conductivity test:

Directional drill rig advancing rods to pull back geothermal loop.
Formation Thermal Conductivity Test Unit
This unit includes: heating elements, datalogger, controls, pumps
The unit is hooked up to the generator.
The generator and thermal conductivity test unit are hooked up to the geothermal loop.
The equipment and loop are under an insulating blanket to maintain
