PyBHT: Model estimates of subsurface temperatures from borehole temperature records

PyBHT is a model code that calculates formation temperature from time series of three or more bottom hole temperatures (BHT) recorded at the same depth. The model simulates cooling as a result of drilling and the subsequent thermal recovery using an explicit finite difference solution of the radial heat flow equation. Formation and borehole temperature are calibrated using the downhill simplex algorithm provided by Scipy.
