One of the essential aspects of visualization is the ability to view and analyze the data and information in many different platforms at varying scales. 2D, 3D, or 4D seismic data analysis involves the interpretation of a large volume of subsurface attributes. While a more complete analysis and visualization requiring collaboration may use visualization centers for better results, smaller platforms such as laptops can be sufficient when scaling 3D seismic data for visualization and analysis. The ability to integrate non-seismic data into the interpretation in its correct geospatial position, process, and scale them for any size visualization platform provides interpreters the unique opportunity to view the data in 3D or 4D while collaborating with multi-discipline asset teams.
Visualization of 3D Seismic Data in Multiple Platforms
Efficient seismic interpretation requires the inclusion and integration of seismic exploration data and models with a wide range of non-seismic geological and petrophysical data. Visualization enhances this analysis by converting these diverse ranges of data sets into 3D simulation models. Often, the integrated data sets are multi-dimensional and may require complex analysis and visualization. While smaller platforms like laptops are capable of visualizing large datasets via high-resolution displays, they may not be as sufficient for analysis.
Software platforms such as CoViz 4D provide geologists, geophysicists, and reservoir engineers with a wide range of data manipulation and analysis abilities, such as:
- Importing processed seismic data and interpreted seismic cubes and co-visualizing them with other relevant reservoir data
- Performing correlation analysis of well logs, reservoir simulations, gravity, and magnetic data
- Comparing grids and models to see where data doesn’t align or where uncertainty exists
- Computing time-step differencing to analyze the seismic response
Scaling 3D Seismic Data in Various Formats
In order to visualize a wide range of interpretations efficiently and in high-quality resolution, CoViz 4D is able to present data and models in different viewing configurations that show compatibility with a wide range of visualization and display platforms. CoViz 4D allows the processing and saving of data files in .vue or .vlist format which allows files to be displayed in a wide range of settings and parameters.
A .vlist format allows a series of specific views to be saved in a single file. This allows asset teams to present the files as a presentation with multiple slides or frames. Interpreters can also use annotations such as texts or images in these file types. Each frame in the file can be deleted or reinserted in a sequential format to allow teams to visualize data in a consecutive and interactive pattern.
CoViz 4D: Enhanced Collaboration and Interpretation
Dynamic Graphics Inc.’s CoViz 4D has the capability to incorporate multi-dimensional data in their correct geospatial position, into any scale computer platform and provide the user with a unique and complete ability to view a variety of data in 3D or 4D. CoViz 4D fosters information sharing and collaboration with teams by processing the data easily and quickly—which is especially helpful during team meetings and presentations. The software’s ability to scale 3D seismic data and other cross-correlated data enhances team communication allowing them to make effective and economic decisions.
