Borehole thermal recovery sensitivity tests: COMSOL base model, MATLAB analysis scripts, and parameter sweep results.

This dataset contains the COMSOL base model, MATLAB scripts, and sensitivity test results used to investigate borehole thermal recovery as a method for quantifying subsurface permeability. The COMSOL model is used to run the parameter sweep simulations by changing selected parameters. MATLAB scripts are included for analyzing temperature–time series and fitting exponential decay functions. Result files (.mat) contain paired vectors of time and residual temperature for individual sensitivity tests, including variations in permeability, formation thickness, depth, flow rate, and flow duration. These files support the study by Purwamaska and Fulton on borehole thermal recovery and are intended for reuse by researchers interested in hydrogeology, permeability estimation, and borehole thermal methods.
