T2Well/EOS7NC (EOS7NC) v1.0Beta

Abstract

T2Well/EOS7NC extends TOUGH2/EOS7C to include the choice of any three of a variety of non-condensable gas components and adds the coupled well-reservoir capability of T2Well. T2Well/EOS7NC is applicable to geologic carbon sequestration, CO2-enhanced gas recovery, compressed air energy storage, geologic hydrogen storage, and other subsurface porous-media injection/withdrawal processes involving non-condensable gases. The advantage of T2Well/EOS7NC over TOUGH2/EOS7C is that TOUGH2/EOS7C is restricted to modeling CO2 or N2, a gas tracer, and CH4 whereas T2Well/EOS7NC can model and three non-condensable gas components chosen from a long list within the code. In addition, T2Well provides the coupled well-reservoir capability.
