Stratigraphic modeling and the Stratigraphy strip

The concept of the stratigraphic modeling workflow is the creation of accurately defined zones and the development of the hierarchy that governs these zones. The goal is to create the modeling framework by combining the available data and apply a stratigraphic hierarchy upon them in such a way that it captures enough detail and contains the important fluid boundaries.

The stratigraphic levels that are created from this hierarchy are used to define the construction sequence during the creation of the 3D structural model. The separation of levels also allows you to construct a structural model based on specific levels. Using this approach, you could first create a model for the highest stratigraphic level (Level 1) that contains the most important zones.The model can be complemented with the successive zones at deeper levels (Level 2, 3, etc) that are perhaps only defined by markers.

The Stratigraphic Modeling workflow in the Stratigraphy strip (prepare > Stratigraphy) contains the functionality needed for defining these levels and zones in your stratigraphic model, creating zones and associating events with those zones. In order to use your stratigraphic model later in the structural model or 3D grid, you need to set a top and base event, represented by a marker or horizon interpretation within your project, to each zone and at all levels. The actual horizon or marker will be 'assigned' during the creation of the 3D structual model and 3D grid. Various tools are also provided to aid you in developing your model, such as those for creating zone logs and automatically generating events in manually defined models.
