RTM

Reverse time migration (RTM) is an ultra high-end prestack two-way wave equation migration for accurate imaging in and below areas with both structural and velocity complexities.

Historically, RTM has been considered impractical because of high computational costs and a greater sensitivity to velocity and reflectivity parameters. However, large parallel compute clusters, coupled with more accurate velocity model building workflows, now make RTM a viable option in the imaging portfolio.

We have extended RTM to include both tilted transverse isotropy (TTI) and vertical transverse isotropy (VTI), and it is fully compliant with the latest multi-, wide-, and full-azimuth geometries.
