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.
