An Unstructured Depositional Grid for Property Modeling

The presentation first develops a transform from geological space to depositional space based on large deformation elasticity. A depositional grid is constructed using this mapping. It is shown that this grid, even though it is unstructured and capable of modeling complex geology, can be used directly in geostatistical modeling without a need for an upscaling step as is more usually the case for performant unstructured grids.
