Abstract
ISTRICI was developed to facilitate the use of Seismic Unix, a free software designed to process seismic data. Seismic Unix is a powerful tool for performing pre-stack depth migration and using the residual parameters to update the seismic velocity model based on the pre-stack depth migration results. What is missing are codes and scripts that allow practical, interactive, and easy application of the Seismic Unix algorithms. Therefore, ISTRICI was developed to fill this gap. ISTRICI consists of three workflows (INTER, CIG and TRAD) for interactively performing residual velocity analysis and pre-stack depth migration, switching from one workflow to the next depending on the characteristics and type of seismic data. To demonstrate the flexibility and efficiency of our package, we describe the application of this tool on marine seismic data.
