Seismic Processing
Our group is responsible for the operation, and maintenance of the Energy Resources Program’s 2-D and 3-D seismic reflection data processing facility located in Denver, Colorado. We process newly acquired seismic data, and re-process older vintage data. These data can be either single or multi-channel 2-D seismic lines, or 3-D seismic data cubes. Also included in our responsibilities are various geophysical analyses of well logs. The end products we generate provide detailed subsurface structural and stratigraphic information which provides the foundation for geologic based hydrocarbon resource estimations, petroleum reservoir characterization, basin analysis, fluid flow modeling, geologic framework studies, characterization of petroleum systems, recognition of geologic hazards, and the analysis of hydrologic systems.

Hardware
We are currently using a dual processor IBM IntelliStation A Pro to process both our 2-D, and 3-D data sets. This workstation is running an Enterprise version of Red Hat Linux. We have almost completed the migration of our processing capabilities from our SUN Sparc based workstations. All of our users have the capability to use their desktop PCs to connect to and process on the workstation via a secure connection.
Software
In processing seismic data, the geophysics group has at its disposal, both ProMAX 2-D and ProMAX 3-D. Our license configuration currently allows three simultaneous users to process data. Myung Lee, John Miller, Harold Oliver, Nick Zihlman, and Warren Agena all have many years experience in using this software and Myung has written and continues to write software modules that we incorporate into the ProMAX processing environment.

Seismic Interpretation
For interpreting and vizualizing seismic data, we have two main software packages, one PC based and one workstation based. For relatively smaller sized interpretation/vizualization projects, we use the PC based GeoGraphix by Landmark and for larger projects requiring huge amounts of data manipulation, we use the workstation based OpenWorks by Landmark. Larson Software Technology (LST) is used to plot all of our workstation based seismic displays.
