Converted Wave Processing Sequence

• To get the most value out of converted wave data one must have a good handle on:

  • P-wave velocities
  • Anisotropy, or eta
  • Gamma to correlate P to PS data
  • S-wave velocities
• Use of variable parameter migration is helpful
• S-wave sequence:
  • Estimate gamma
  • Migrate with initial s-wave velocities
  • Pick Vs
  • Test veracity of gamma
  • Iterate previous two steps
  • Migrate with final s-wave velocities

Workflow to properly define gamma and s-wave velocities for converted wave migration.
