Compositional effects in thermal, compositional and reactive simulation

This work studies the influence of several compositional effects on thermal and reactive processes. First, impact using a fully model in context simulations is considered. Detailed phase behavior models rely descriptions oil up to tens components. Lumping large number components into smaller pseudo-components order reduce computational cost standard practice for simulations. schemes are typically calibrated experimental data, achieve good approximation initial oil. Due evaporation condensation under stimulation, composition will widely vary time space. works illustrates that even if lumped were able capture oil, lack resolution can lead modeling artefacts and/or fail relevant displacement Then, different interpretations pseudo-species appearing typical reaction investigated. A constant, mass-based fraction allowed react, modified. molecular weight effects, rate larger when light medium react. Those result an increased displacement, leading faster fronts, banks more pressurization system.
