Developing a data processing framework for analyzing borehole temperature profiles in geothermal heat pump systems with DTS technology

Objectives of the thesis

A distributed temperature sensing system (DTS) has been installed in 2016 in two different boreholes. It has been detecting the ground temperature of the two close boreholes, at different depths, at each time step. One of the two boreholes has been actively used along this period of time, while the second one was only used for experimental porposes, rarely subjected to heat injection or extraction.
Building upon the significance of accurate data management in geothermal research, the objectives of this thesis are:
1. To develop a structured and reproducible methodology for processing borehole temperature data.
2. To analyze temperature patterns and the historical interaction between two boreholes of the same field.
3. To lay the groundwork for future testing and system optimization.
