The World’s Leading Geometry and Statics Solution
Seismic StudioTM is the premier statics solution for challenging land andmarine data sets where shallow subsurface velocity and geometry prob-lems degrade the quality of seismic data. In addition, geometry problemscan be identified and corrected.
2D and 3D Geometry Corrections & First Break Picking
Robust seismic processing requires accurate geometries, yet typical landand marine OBC surveys often have errors in source and/or receiver loca-tions that can significantly degrade the integrity of the seismic data andlater processing workflows. Seismic Studio interactively determines seis-mic geometry errors and allows the user to correct them with ease.
Interconnected windowsallow the user to pick firstbreaks simultaneously inseveral sort planes. Auto-matic picking and guidedpicking speed up theprocess, as well as pickprediction based on analysisof sparsely picking every“Nth” source gather.

the quality of first
break picks.
Refraction Statics
Seismic Studio provides numerous diagnostic displays for the analysis and creation of the near surfacemodel and computation of refraction statics.
Assigning first break picks to refractor ranges.
Refractor velocities.
Cross-section of model can be seen in
arbitrary orientations.
Refractor delay times.
Tomographic Statics
When refraction statics can't addressall of the complexities of the shallowvelocity field, such as high-velocityzones in low-velocity layers, tomo-statics can provide the answer. Seis-mic Studio includes a verysophisticated hybrid tomostatics al-gorithm that is designed to addressthe most difficult velocity challengesin complex geologic settings.
Stacking Capability
A powerful feature in Seismic Studio is the ability to perform stack comparisons of your statics solutions in anyorientation through your 3D data.
Cross-section of tomographic model.
Stack comparison of elevation statics vs. hybrid tomographic statics.
