The 3D Gridding workflow

After you have developed a 3D structural model, you are ready to create a 3D grid that you can use for volumetrics and simulation of your reservoir or other geological models. Most manual work has been done, and creating the 3D grid is largely an automatic process, guided by the steps on the 3D Grid strip (Model > 3D Grid).

The first step in creating a 3D grid from your structural model is to actually create the grid as a placeholder in the JewelExplorer. You then assign data to this grid by selecting the structural model to use. Next, you can edit your grid, if needed. You then need to assign an area to the grid, including attributes such as cell size and the number of cells, before finally creating the grid.

The 3D grid creation shares the same logic as used in the 3D structural modeling workflow, as both modeling steps are based on the hierarchy of the stratigraphic model. The latter serves as a building template that determines the sequence in which the elements are built and depend on each other. For example, whether a zone is contained in another one and how the corresponding layers should be aligned. As the 3D grid is built on the basis of a 3D structural model, the building sequence is inherited.
