An update of MATLAB-EOM for converted wave data

John C. Bancroft and Thais A. Guirigay

ABSTRACT

The MATLAB code for equivalent offset migration has been updated to include the processing of converted wave data. This new procedure estimates a converted wave velocity that is then used to estimate a shear wave velocity. The compressional and shear velocities are then used in the double-square-root equation to compute traveltimes.

Parameter options are defined. Some of the new parameters define a limited offset and spatial range during the gathering process to form converted wave gathers with one converted-wave velocity.
