Five Spot Demo

November 23, 2010

This video demonstrates input, execution, and analysis of the 5-Spot Geothermal Production/Injection example presented in the TOUGH2 User's Guide. PetraSim is a graphical interface for TOUGH2, TOUGH2-MP, T2VOC, TMVOC, TOUGHREACT, TOUGH-Fx/HYDRATE, and TETRAD. These simulators are recognized for their powerful simulation capabilities involving fluid flow and heat transfer in porous and fractured media.
