For example, EOS3 describes water and air which can exist in single or two-phase conditions and can be used for groundwater or geothermal applications. EOS7C includes methane-carbon dioxide or methane-nitrogen gas mixtures. Applications include subsurface geologic carbon sequestration sites and natural gas reservoirs. The components modeled include water, brine, non-condensible gas (CO2 or N2), gas tracer, methane, and heat.
All EOS module executables are optimized and integrated into PetraSim, so no further compilation is required. The user just clicks and runs. If you have developed a modified variation of TOUGH, support is provided to pre-process and post-process those results also.
