ABSTRACT: 3D Visualization of VSP Solutions

We have developed a 3D visualization tool specifically for vertical seismic profiling (VSP) solutions. 3D VSP visualization applications often involve multiple datasets with a large number of different types of property parameters, including grid-based velocity models, layer models, surface seismic volumes, VSP migration image volumes, log data, interpretation results, and many more. Interpretive integration of these multiple datasets will better characterize reservoir structures. Viewing and interpreting this data requires the interactive manipulation of multiple data volumes in a highly efficient fashion. VSP volumes generally cover a smaller, but overlapping segment of the 3D seismic volume. The desire to display 3DVSP volumes within the larger 3D surface seismic volume complicates visualization control. Simultaneous 3D VSP and surface seismic visualization requires the capability to handle all of the data information in a simple and robust manner. Our objective is to simplify the display control while still offering the geophysicist a great deal of flexibility for data display and manipulation. 
Applying Java 3D technology, we have implemented a portable 3D VSP visualization package that can be operated on multiple computer platforms. Users may import any dataset and display all of them right away. To adjust display parameters or any objects properties, the user simply selects the object and a uniform control panel will appear for making changes. This simple convention is maintained for all types of objects, making the tool very user friendly. Other capabilities include creating movie files, saving the current display, and creating 3D stereo displays with a one-button click. We will demonstrate the application using synthetic data, as well as actual data acquired in the Gulf of Mexico to show that this is a simple yet powerful geophysical tool.
