Gaussian Packet Migration (GPM) Imaging

Our Gaussian packet migration with full image-gather output offers a new migration approach in terms of speed, frequency content, and underlying algorithm. GPM is capable of creating high-resolution steep-dip images in complex environments or high-frequency images for post-salt targets where stratigraphic resolution is key. In addition, GPM can handle all forms of WAZ, NAZ, or FAZ acquisition and ISO, VTI, and TTI data.

GPM features

  • Accurate solution to the acoustic wave equation
  • Handles amplitudes and wavefront curvature through dynamic ray tracing
  • Honors multipathing wave propagation
  • Localized in space and time
  • Enables real-time prestack depth migration
  • Always outputs gathers
