Thermal Properties Card (EOR)

STOMP-EOR is designed to solve problems involving the transport of energy, water, CO₂, CH₄, salt, and a user-defined number of petroleum components with passive solutes or reactive species through variably saturated geologic media under non-isothermal conditions.  The Thermal Properties Card allows the user to specify thermal conductivity models and parameters and grain specific heat as an intrinsic property of the rock/soil. Every rock/soil type defined on the Rock/Soil Zonation Card must be referenced. With the IJK Indexing option, node dependent parameters are entered via external files and node independent parameters are entered directly on the card. This card is required only for simulations involving the solution of the energy conservation equation. Declaration of the thermal conductivity depends on the operational mode and function option. The current version of STOMP-EOR only provides two thermal conductivity model options: 1) parallel function and 2) Somerton function.  The parallel function option requires the user to specify the rock/soil grain thermal conductivity.  The effective thermal conductivity of the grid-cell then depends on the porosity, saturation states of the fluids, and the thermal conductivity of the fluids.  The parallel function is a simple volume-weighted averaging model.  The Somerton function requires the user to specify the dry bulk rock/soil thermal conductivity and the aqueous-wet bulk rock/soil thermal conductivity.  The effective thermal conductivity of the grid cell then depends on the aqueous saturation of the grid cell.  The grain specific heat refers to the specific heat of the rock/soil grains, not the bulk specific heat.
