Flexible Modeling Approaches
Classical modeling approach.
Build your 3D conceptual model using existing GIS data and wells/boreholes. The grid-independent conceptual model gives you the flexibility to experiment with different grid types and simulators. Cell locations and parameters are automatically calculated for you, reducing the need to define these manually on a cell-based level. From one conceptual model you can easily generate multiple numerical models of different grid types and modeling scenarios, and easily update or modify the model as needed.
