Tsunami™ Prestack Time Migration
Tsunami™ PSTM is a Kirchhoff based prestack time migration. It can be run using either straight ray or curved ray travel times. The curved ray travel times can use either the 6th order NMO equation or the eikonal method to calculate the travel times. The migration will image beyond ninety degrees which will allow the use of turning waves to image salt overhangs.
Tsunami™ PSTM can image from a fixed datum or a floating datum/topography as your project requires.
With Tsunami™ PSTM you have complete control of the output you can generate. You can select the inlines and crosslines you wish to output as well as the offset ranges and increments.
You have the ability to specify the migration aperture as a function of time and the output frequency as a function of time. This allows you to optimize imaging performance by specifying dips and frequencies needed by your particular job.
