11.13.2 Unstructured Column-Layer Grid Representation

Topic Version1Published09/11/2015
For StandardRESQML v2.0.1

The unstructured column-layer grid is based on the unstructured column-layer cell geometry, and hence the column-layer cell geometry. In a 2D sense, these grids are not structured, and all column and pillar adjacency information is explicit. However, just as with IJK grids, there is a well-defined global layering within these grids, which holds for all columns.

The grid description for an unstructured column-layer grid (Figure 11.13.2-1) has many of the same elements as the IJK grid. However, unlike an IJK grid, RESQML provides no optional extensions, because none arise in current industry practice. If such a requirement does arise in the future, then the general purpose grid description is available for use.
