Requirements for 3D gridding differ substantially depending the type of processing that is being considered. For example, for complex faulted systems, honoring orthogonality that is required by flow simulators for better numerical accuracy can be achieved using a stair-stepped grid. This grid however is not fit for geomechanical simulations since geometrical movements resulting from simulated stress changes require smooth surfaces along faults.
Forcing a single grid for all processes to account for all requirements leads very often to oversimplified models and questionable results. On the other hand, using different and unrelated grids leads to challenges in collaboration and consistency.
In this presentation, a portfolio of fit-for-purpose grids for wide range of reservoir modeling and engineering applications is presented. These grids are optimal for the simulations they are used for while preserving geological integrity. They are representations of a common subsurface model ensuring consistency, fast model update cycles and accurate data and uncertainty propagation between the different disciplines.
