Résumé :
Multiphase Hydrocarbon Vacuum Enhanced Recovery with Transport
BIOSLURP, by RASI is an areal finite-element model to simulate three-phase (water, oil and gas) flow and multi-component transport in ground water in the unsaturated zone gas phase. Currently the most advanced model of its kind, BIOSLURP can be used to optimize the recovery of LNAPL, water, and gas by minimizing NAPL entrapment in the saturated/unsaturated zones, and simultaneously simulate multispecies aqueous and gas phase transport in unconfined aquifers. BIOSLURP can also simulate coupled flow of water and LNAPL with a static atmospheric gas phase.
BIOSLURP simulates heterogeneous, anisotropic porous media or fractured media. It allows use of isoparametric elements to accurately represent material and physical/hydraulic boundaries.
BIOSLURP can be used to design NAPL recovery and hydraulic containment systems for the free phase hydrocarbon plume and dissolved phase plume under complex hydrogeological conditions. Bioslurping (vacuum enhanced recovery) increases gradients in water and oil potentials with minimal fluctuations in the fluid tables and thus helps to reduce volume of residual product and enhance free product recovery. BIOSLURP has the following key features:
• The preprocessor allows import of DXF site maps.
• Initial fluid pressures, species concentration distribution, and free oil volume are estimated internally from the monitoring well fluid level data.
• Rectangular and/or isoparametric quadrilateral elements to accurately model irregular domain and material boundaries.
• Bioslurping (vacuum enhanced recovery) of NAPL and water phases is simulated.
• Areal distribution of oil, species mass, and contaminant loading to ground water and vadose zone updated continuously.
• Convection, dispersion, diffusion, adsorption, microbial processes based on first order, and oxygen-limited biodegradation kinetics in water and gas phases.
• Spatially-variable water recharge, injection or LNAPL leakage.
• Model multiple pumping and/or injection wells.
• Model specified head, specified concentration, and flux conditions for flow and transport.
• MATRIX SOLUTION BY CONJUGATE GRADIENT METHOD.
• Simulate fractured media or granular porous media.
