Purpose: To flatten 3D seismic data (or attribute volumes) so that we can slice through the cubes to pick up stratigraphic details. Theory: Stratal slicing (or proportional slicing) is the interpolation option of the model-driven mode for creating chrono-stratigraphic horizons. It is the mode in which the thickness interval between mapped top and bottom horizon is distributed equally over the number of chrono-stratigraphic horizons. Software: OpendTect + Dip-Steering + SSIS
Workflow:
Select a pre-calculated chrono-stratigraphy.
Create a Wheeler Cube. (This step is required for displaying data in a Volume viewer in the Wheeler domain.)
Add a Wheeler scene and load the Wheeler cube in the Volume viewer. Use the time slicer to movie-style, inspect the data. Remember that a time-slice in the Wheeler domain corresponds to a horizon slice in the Structural domain.
Tips:
To improve time-slicing in the Wheeler domain you need to improve the underlying chrono-stratigraphy, which can be done by adding more mapped horizons.
