Multiphase filtration modeling of complex structure reservoirs on dynamic adaptive PEBI-grid
Abstract
The paper presents generation methods of dynamic adaptive unstructured PEBI-grids for efficient multiphase filtration modeling of complex structure reservoirs with multiple structural and technology features (faults of complex geometry, inclined and horizontal wells, including hydraulic fracturing). We have developed the algorithm of local grid rearrangement due to newly opened wells and hydraulic fracturing, reducing simulation time. Three-phase filtration problem has been solved numerically, accounting for gravitational, viscous and capillary forces and phase transition of hydrocarbon components. Original numerical method for direct flow computation in hydraulic fractures is proposed.
