VISTA* desktop seismic data processing software is a Windows® application. Arsenal of DVD and web-based user resources.

VISTA desktop seismic data processing software provides data processing from early-stage acquisition QC to final processing and interpretation of 2D and 3D seismic data acquired on land or offshore or as a vertical seismic profile (VSP), in all industry and manufacturer data formats. With VISTA software, you can easily navigate workflows and seamlessly evaluate datasets using the interactive and interlinked displays. You can also add in your own algorithms through a C++ or MATLAB SDK interface. The software supports advanced processing capabilities including AVO and angle of incidence (AVA) analysis, multicomponent processing, and 2D and 3D VSP processing.
