(Use Case Vocabulary) geothermal borehole - opengeospatial/boreholeie GitHub Wiki
Summary
Borehole(s?) deployed to exploit geothermal resource (heat or electricity generation). But also geothermal probe deployment to assess subsurface heating storage capacity via Ground Thermal Response Testing (TRT).
Terms
Concept/Feature: Borehole
Definition
"A borehole is the generalized term for any narrow shaft drilled in the ground.". INSPIRE definition (removing ", either vertically, horizontally, or inclined." from the initial GeoSciML one).

Concept/Feature: Thermal Response Test (TRT)
Definition
"Thermal Response Test (TRT) is a measurement method to determine heat transfer properties of a borehole heat exchanger and surrounding ground in order to predict the thermal performance of a ground-source energy system." (from http://projects.gtk.fi/Annex21/trt.htm).

Concept/Feature: Thermal Response Test Observations
Definition
"Observations generated by the TRT and associated ones necessary to understand it." ground temperature, probe observed thermal resistivity, mean ground thermal conductivity, rock material specific heat (chaleur spécifique in French -> regionalized abacus of some sort).
Properties/Attributes
observations & measurements properties seem ok :)
Concept/Feature: Geothermal log
Definition
"Log representing geological units heat storage capacity. Based on native geological log + local studies."
