Thermal Gradient Holes:
"A hole logged by a temperature probe to determine the thermal gradient. Usually involves a hole less than 500 ft deep drilled specifically for this purpose"
Other definitions:Wikipedia Reegle


 
Introduction
"Thermal gradient holes are typically shallow holes that are drilled and surveyed with a temperature probe. Designing a drilling program that will maximize the information based on orientation of the reservoir and faults can reveal an abundance of information about the hydrogeology and thermal properties of the deeper hydrothermal system (Smith, 1983; Coolbaugh, et al., 2007). Innovations in measuring temperature profiles in wells and projecting thermal anomalies beyond the temperature measurements have led to moderately accurate depictions of the hydrologic system." cannot be used as a page name in this wiki.

Use in Geothermal Exploration
"Temperature gradient holes are very useful in revealing hydrothermal properties of a geothermal system, ultimately decreasing the risk associated with drilling deeper and wider wells for further exploration or production. Thermal gradient holes are used for locating broad hydrothermal characteristics of a resource. They do not have the accuracy of predicting reservoir temperatures or depths. Although, if an array of thermal gradient holes are drilled across a field then more details will be revealed about the resource and its hydrologic system. Thermal gradient holes can provide important information about a resource increasing the confidence and likelihood of targeting a high temperature resource." cannot be used as a page name in this wiki.
