STAR Geophysics, Inc. is a full-service Seismic Data Processing company serving the Oil & Gas Exploration industry since 1986. We are located in the downtown business district of Oklahoma City, Oklahoma, and have applied our skills to projects throughout the world from the smallest 2D lines to 3D surveys of well over 1000 square miles. From our uniquely experienced staff of Senior Processing Geophysicists to our most recent college graduates, STAR’s goal is to provide and maintain the highest level of expertise. We emphasize in-house mentoring and have a serious commitment to professional development through continuing education and professional society affiliation. Our service offerings include a full suite of 2D and 3D processing methodologies, a broad selection of pre- and post-stack imaging algorithms, expert seismic velocity analysis, interpretive processing including AVO and attribute analysis, data transcription and copy services, as well as 3D survey design and project management.
2D/3D Services Imaging Techonlogies
Basic processing is conducted within Landmark’s SeisSpace/ProMAX seismic data processing suite. As a package that allows us to organize projects effectively and that contains all of the most essential routines normally included in our process flows, it provides a platform for highly customizable approaches to the many unique situations presented in modern seismic exploration. The flexibility inherent in SeisSpace/ProMAX and its continued development with new routines that reflect the most recent advances in the field, provides us the opportunity to bring to bear our many years of experience and attention to detail to deliver reliable solutions to the increasingly sophisticated requirements of our clientele.
Seismic Time and Depth Imaging
STAR Geophysics incorporates a broad range of imaging technologies into its 2D and 3D seismic processing services. The offerings include a wide variety of pre-stack and post-stack migrations in both time and depth domains.
Pre-Stack Time Migration
Our most requested product is 2D or 3D Kirchhoff Pre-Stack Time Migration which is a highly accurate imaging method applicable to many geologic settings and is most often performed at STAR using the Tsunami Imaging Suite. This world-class time migration implementation features options for straight or curved ray algorithms, ETA field input for anisotropic corrections, and an optional converted wave mode. The ability to directly output angle gathers for subsequent AVO analysis is another distinctive feature of this program.
Pre-Stack Depth Migration
STAR’s implementation of 3D Kirchhoff Pre-Stack Depth Migration also incorporates the Tsunami Imaging Suite. Featured in this application is the ability to use turning waves to image beyond ninety degrees (as with salt overhangs). Travel-time files are built using a ray-tracer program based on wavefront reconstruction. Velocity updates for iterative image improvement are based on tomographic inversion from residual moveout picks of the depth migrated CRP gathers.
Post-Stack Time and Depth Migration
We also offer a wide variety of post-stack migrations included in our general seismic data processing platform Seis Space. Various methods including Kirchhoff, Finite-Difference, Phase Shift and Stoldt are available.
