Vista Seismic Processing Tutorial Pdf

This modern introduction to seismic data processing in both exploration and global geophysics demonstrates practical applications through real data and tutorial examples. General Processing Flow Seismic processing flow is a computer program Implemented as a 'script' (DISCO, SIA, SU), 'instruction list' (ProMAX), or visual 'graph' (Vista, Omega) User builds the processing sequence using a collection of tools for data manipulation Results in generation of a code customized to perform the specified task.

1 VISTA Desktop seismic data processing software VERSION 2015 2 VISTA Desktop seismic data processing software Comprehensive seismic processing and QC software VISTA* desktop seismic data processing software is a Windows application built on proven algorithms for optimal quality control from field acquisition to final processing and interpretation, eliminating the need for specialized Linux hardware platforms and support personnel. In today s time-compressed environment, VISTA software provides users complete control over their assets with flexibility, reliability, ease of use, and compatibility with all industry and manufacturer data formats.
