3D Land Processing in the Foothills

Audience

Land processing geophysicists (time and depth).

Content

This course teaches the land processing workflow from a floating datum (a smoothed version of the topographical surface) using the double square root equation for NMO and velocity analysis.

This method is best used in areas of large elevation changes (more than a few hundred meters), as it minimizes errors introduced by non surface consistent static corrections and conventional NMO.

It may yield more robust velocities and better continuity of events on stack sections, and it uses surface consistent statics which are required for data input to pre-stack migration. Furthermore, the DSR NMO equation is the same as the one used in pre-stack time migration, so should we want to apply such migration, we will be maintaining consistency throughout.

Learning Objectives

  • Describe how this technique works
  • Know all geovation modules and interactive applications used in the workflow
  • Process a real 3D land dataset in geovation using this workflow
  • Know the advantages and limitations of the method
