PSTM (Pre-stack Time Migration) includes straight ray, curved ray and eikonal travel times. Turning waves are supported for imaging beyond ninety degrees, which is useful for imaging salt overhangs or over thrust geology. PSTM includes AVO-compliant amplitude preservation techniques, and is often th ...

PSDM (Pre-stack Depth Migration) uses the Tsunami Ray Tracer to calculate travel times tables. The travel times may be obtained from first arrivals, maximum energy, minimum distance or, eikonal calculations. PSDM supports ISO, TTI and VTI modeling. Tsunami Desktop Solutions are used to build epsilon ...

TOMO is a second generation, grid based tomography. It includes sophisticated software for gather conditioning and picking residual velocities which are key to superior results. New features include: “Multi-pass” grid cell refinement with each iteration User specified velocity constant which may ...

RTM (Reverse Time Migration) is a shot domain migration. Tsunami's RTM implements wave propagation calculations in a highly parallel environment for efficient propagation of the waves through subsurface media. By storing every source wave time step it solves the problem of reverse order access to th ...

Hi-FI is an application that allows the user to get substantially higher resoution from conventional seismic data. This improved resolution is achieved by performing reflectivity estimation by using an inversion process to remove the wavelet from each seismic trace and then reconstruct the trace wit ...

Tsunami’s GatherView is a multi-tool box solution for your gather conditioning and interpretation needs. Build custom workflows by dragging and dropping any of our 15 modules to the workflow builder, and watch as your conditioning is applied in real time to your selected gather or stack. Either time ...

  The Semblance plug-in is used to pick velocity-time pairs and ETA-time pairs based on hyperbolic searches for coherence between multiple seismic signals in migrated gathers. The goal of this utility is to provide a robust velocity analysis to aid in further iterations of migration. In Tsunami’s S ...

WHAT IS DEPTH SEMBLANCE Tsunami’s depth semblance tool allows the user to manually update velocity models by estimating the residual NMO needed to correctly flatten a gather in depth. The user can pick interval velocities and epsilon values at the same time to correctly flatten a gather. Additional ...
