VISTA IVA is a powerful, highly interactive velocity analysis application for 2D and 3D seismic data that brings versatility and efficiency to the velocity analysis workflow in the time domain. It provides multiple options for the robust analysis of velocity and eta, with various moveout methods available for isotropic and anisotropic media.
Users of the app can easily create and adjust input datasets without leaving the application. Sophisticated QC tools enable efficient validation of velocity models using visual 3D displays, including real-time brute stack updates.
VISTA IVA enables users to efficiently manage multiple 2D lines and transfer velocity and eta picks from one 2D line to another at intersection points.
