Northwestern Michigan College Formation Thermal Conductivity Test Report
This report summarizes a formation thermal conductivity test performed July 29-31, 2025 on a579-ft vertical bore at Northwestern Michigan College in Traverse City, Michigan. It describes the test setup, operating conditions, data acquisition procedures, calibration details, and bore construction information, with loop temperatures and heat-input measurements collected at five-minute intervals. Using the line-source analysis method consistent with ASHRAE and IGSHPA guidelines, the test produced an average formation thermal conductivity of 1.34 Btu/hr-ft-F, accompanied by figures and summary statistics documenting the measured response.
