Migration Algorithms

Kirchhoff Pre-Stack Depth Migration (KPSDM)
KPSDM is a full Kirchhoff-diffraction summation algorithm that includes state-of-the-art anti-aliasing filters, full VTI and TTI anisotropy and Beylkin amplitude corrections.

Travel times are computed by a dynamic ray tracer using the wavefront reconstruction technique, yielding very accurate results, as well as dynamic amplitude corrections.

KPSDM is fully parallelized and scales linearly to thousands of cluster nodes.

Wave Equation Migration (WEM)
Wave equation migration is a shot domain migration based on the paraxial approximation of the full wave equation.

Regularization is handled within the migration and an adaptive grid size is chosen dynamically during run times.

Angle gathers can be computed, and a VTI implementation is available.

Reverse Time Migration (RTM*)
Reverse time migration is a wave equation migration algorithm where no approximations have been made. It suffers from none of the shortcomings inherent to the WEM and has a full dip response capable of imaging turning rays.

Reverse time migration can generate illumination volumes based on the 2-way wave equation.
