Shallow geothermal projects are commonly framed in terms of conductivity, heat capacity, borehole resistance, and thermal response tests.

In groundwater-active settings, these thermal descriptors may be incomplete. Flow can advect heat, boundaries can distort the response, phase and amplitude can imply different properties, and early-time borehole storage can be confused with formation properties.

A site-specific groundwater assessment clarifies when groundwater conditions control the reliability of thermal interpretation.

For industry partners, the question is concrete: does the TRT or thermal field interpretation support scale-up, or does it need a model-assumption review first?
