Surface Flux Card (EOR)

STOMP-EOR has two core implementations: 1) compositional and 2) black-oil. Under the compositional option, STOMP-EOR solves coupled conservation equations for energy, water mass, CO₂ mass, CH₄ mass, salt mass, and a user-specified number of petroleum components in variably saturated geologic media with the potential for three mobile phases: 1) aqueous, 2) nonaqueous-liquid, and 3) gas. Alternatively under the black-oil option, the simulator solves problems involving the transport of oil, gas, and salt passive solutes or reactive species through variably saturated geologic media under isothermal conditions. The simulator additional solves equations for the transport of passive solutes, allowing for partitioning of the solutes between the host rock/soil and mobile phases.  When the ECKEChem module is implemented with the simulator, the simulator has capabilities for solving reactive transport problems involving equilibrium, kinetic, and conservation type geochemical equations.  For this operational mode the fluxes of interest are those associate with advection of the aqueous and gas phase, and heat transport. If the simulation involves passive solutes, the Surface Flux Card is used to specify the output of transport rates and integrals of solutes crossing grid-cell surfaces.  Likewise if the simulation involves reactive species and code implementation includes the ECKEChem module, then the the Surface Flux Card is used to specify the output of transport rates and integrals of solutes crossing grid-cell surfaces.
