11.12.1 IJK Grid Geometry

The IJK grid geometry is a column-layer grid geometry together with a mandatory specification of the grid parity (left handed or right handed) (Figure 11.12.1-1). Parity is described in Section 11.12.2 IJK Grid Representation 11.12.4 IJK Grid Origin . In addition, IJK grids support areal gaps between columns of the grid through the introduction of additional “split” pillars. These are described using the IJ gaps object.
