Support for EOS7C Added

October 12, 2012
PetraSim now supports EOS7C, a TOUGH2 module for 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. If you want to be a beta tester, please contact Alison Alcott at RockWare (alison@rockware.com).  Read More...
