Linearly Transformed Wave Equation Modeling
, by Zhiming Li
A new wavefield extrapolation algorithm, the Linearly Transformed Wave
Equation (LITWEQ) method, was developed in 1984 (Li, 1984). The method
was originally developed to migrate seismic reflection data.
This paper will show how to use the LITWEQ in the modeling of (1) zero-offset
sections of primary reflections, and (2) nonzero-offset sections (including
common-shot profile, common-midpoint gather and VSP) of all seismic waves,
such as direct arrival, primary reflections, refractions, and multiples. c
