Near-Well Upscaling to Simulate Wells with Hydraulic Fractures

Resumo

An important task in reservoir simulation is to take into account the effect of a hydraulic fracture on the well’s performance. The upscaling method allows efficiently computing the inflow into a well with a fracture on a coarse grid. A numerical near-well upscaling procedure for hydraulic fractures on an unstructured Voronoi grid is proposed. The upscaling procedure is shown to be significantly more accurate than the classical EDFM method.
