T2GEORES: A Python Library to Manage TOUGH2 Simulations on Geothermal Systems

Abstract

Detail numerical reservoir modeling is the preferable approach for a resource assessment once exploitation has started in a geothermal field. Moreover, it can give an insight about the general understanding of a system once some wells have been drilled. At present, TOUGH2 is the main simulator for modeling in geothermal systems. However, due to the fixed format of its input file, creating a large model by manual editing could be time consuming and a source of error. A long the years many efforts have been done through the use of scripting languages to manipulate the string of data on the preprocessing and postprocessing steps necessary to setting up a model, avoiding manual editing of input files and manual output selection. This paper introduces T2GEORES, a Python library developed with aim to be handy and simple, specifically oriented to perform modeling in geothermal reservoirs, providing TOUGH2/iTOUGH2 input files generation capability from mesh creation to parameters setting, creates visualization from outputs of simulations and reduces the time consumed during the calibration process of a model by comparing the outputs with real data from the field such as formation temperature, flowing enthalpy, drawdown pressure and cooling history.
