The main goal of this project is to provide a tool for a new workflow in the interpretation process of seismic data. In this industrial field, "Seismic Reflection Volumes" are analysed together with other data (e.g. "Well-Logs"). This analysis provides a better understanding of the subsurface structures and is the basis for simulations of changes in the formation of cavities when producing gas or oil from wells.
The application provides interactive tools for interpreting and visualizing such seismic volumes and its additional data. Large volumes can be loaded, displayed and processed and additional volumes with different properties can be added as well. Some key aspects are:
- An integrated framework for interactive seismic visualiziation, interpretation and subsurface model construction.
- A novel way of creating these interpretations and subsurface models.
- A novel volume shading approach to enhance the visualization of horizon structures within the volume.
- Live volume deformation for on the fly depth conversion, including exploded views.
Horizons between sub-surface layers are traced, using a seed-point from the user. During this fully automatic tracing, the user can change parameters and interactively correct traced surfaces on the fly, resulting in a much faster interpretation time than with traditional methods in the industry. By assigning a speed of sound to each layer that is bounded by these surfaces, time-depth conversion of the dataset can be achieved. This time-depth conversion is generated on-the-fly. An additional volume view display the deformed volume using a single pass raycasting method with minimal preprocessing.
