Distributed temperature sensing for borehole monitoring

Abstract

The aim of this research is to collect temperatures in wells or boreholes at high spatial and temporal scales to understand groundwater mechanisms, to improve the knowledge of the geology for geothermal exploration, and to perform borehole climatology.

Distributed temperature sensing for borehole monitoring

 

The following photographs were taken during the 2015 field trip to Copiapó and Vallenar. This field campaign was performed with St. Francis Xavier University and Université du Québec à Montréal (Canada). Additional funding was provided by CEDEUS.
