Workflow-based reservoir grid modeling facilitates the construction of 3D stratigraphic grids, for modeling both simple or complex geological depositional environments. Overturned beds, listric faults, inverse or Y-faults, faults terminating in the middle of the layer can all be handled.
Stratigraphic grids are controlled by the top and bottom structures, fault network and wells, and are easily updated as new data becomes available. Within a structural unit, stratigraphic layer boundaries are computed using well marker information, accounting 100% for horizontal well constraints. Within each layer, the stratigraphy pattern may be proportional between top and bottom, parallel to top or parallel to bottom. Flexible areal gridding alignment may be either stair-stepped or smooth in both corner-point and cell-centered grids. The same workflow may be used to construct 3D grids for both geostatistical operations and flow simulations.
The reservoir model may be upscaled and exported for flow simulation using Rescue (Flow Grid), Eclipse and VIP formats. Flow simulation results may be recovered to visualize flow behavior within geological and geophysical models. Using property manipulation techniques, upscaling and flow simulation results may be painted into the fine-scale reservoir model for the purpose of analysis.
