Product details
VISTA desktop seismic data processing software is a leading software package for the full range of processing tasks from field QC to complete processing of 2D and 3D seismic data. VISTA software is used around the world to process land, marine, ocean-bottom cable (OBC), and vertical seismic profile (VSP) data. VISTA software is a Windows application available in four packages scaled to meet user needs: 2D and 3D Field QC, 2D and 3D Field Processing, 2D and 3D Full Processing and 2D and 3D VSP. It is flexible, reliable, interactive and easy to use.
VISTA 2D and 3D Field QC is used in the field to perform rapid QC and simple processing up through to brute stack. The VISTA 2D and 3D Field Pro package provides additional tools for today’s more sophisticated QC requirements, including post-stack migration. VISTA 2D and 3D Full Pro offers a complete QC and processing solution, with all of the field capabilities plus post-stack 2D line-tie and 3D data merge, 2D/3D pre-stack time migration, and time and depth image analysis. VISTA 2D and 3D VSP can be used for complete VSP QC and processing.
