Introduction to CoViz 4D
This class gives a complete, yet concise introduction to the CoViz 4D Viewer and the associated Data Registry. Data imports and procedures are explored, and a range of data types are interrogated and analyzed in the Viewer environment. Later exercises cover topics such as temporal animation, instant volumetrics, statistical tools, and creating vue files. The class is condensed into one day to provide a comprehensive overview in the shortest possible time. (1 day)
Outline of Topics

- Reservoir surveillance visualization
Advanced CoViz 4D
Quantitative Visualization and Analysis within CoViz 4D are the focus of the Advanced class. Hands-on exercises introduce in-viewer calculations such as summing, averaging, and back-interpolation of properties⁄attributes within simulation grids, seismic grids, seismic attribute files, and well logs; these calculations facilitate quantitative comparison and statistical analysis of spatially overlapping, but geometrically dissimilar data sets. Other more specialized features, such as Wellcentric viewing, data queries, and streamline visualization are covered. (1 day)
Outline of Topics
- Focus on Quantitative Visualization and Analysis
- In-viewer calculations
- In-depth use of statistical tools for comparative cross-plots
- Wellcentric viewing
- Data queries
- Streamline visualization
- 4D (time-lapse) seismic and reservoir simulation comparative workflow
The Advanced training course requires a basic knowledge of the CoViz 4D software, including usage of the Viewer and the associated Data Registry. Participation is at the Instructor′s discretion.
Introduction to EarthVision 2D and 3D Modeling
An introduction to EarthVision®, with a primary emphasis on the program′s WorkFlow Manager®. The class uses 2D and 3D data and grids for faults and horizons as components in building 3D structure and property models. Class topics include: data visualization and validation, data editing in 3D, constructing fault hierarchies, building stratigraphic sequences, and constructing the final 3D volume model. The extraction of 2D maps and cross sections from the finished model completes the sequence of activities. Other topics include the calculation of precise volumes, Formula Processor operations for file manipulation, and exploring the program′s powerful Graphic Editor. Upon completion of the course, students will have a solid introduction to building three-dimensional faulted models and will be comfortable using the 3D visualization tools. (4 days)

Introduction to Reservoir Cellular Gridding
This two day course introduces students to Dynamic Graphic′s Cellular Gridding software. EVCELL enables users to quickly and efficiently build cellular reservoir grids that accurately portray the structure and$frasl;or property in an EarthVision 3D model. The course is organized into lectures and demonstrations, along with hands-on exercises. Activities include defining the cellular model space and aligning the grid with major structural feature(s), such as faults. Various fault treatment methods for building cells along faults, including I, J, IJ, and IJK stair-step are discussed, along with the definition of flow units based on stratigraphic geometry and lithologic character. Different property populating methods are examined, followed by export of the cellular grid to the industry standard simulation formats: GridGenr(GTF), VIP, ECLIPSE, CMG, FLOGRID, and RESCUE. By the end of the course, students will have experience building, examining, QC′ing, and exporting cellular grids (3 days)
