Developed to Madagascar package, version 2.0.
This package is a set of Madagascar SConstruct scripts to simulate several diffraction hyperbolas in a Stacked Section and migrate with a velocity model that produce best focusing of the simulated hyperbolas. It uses recipes (python functions) called inside SConstructs to migrate the data with simulated diffractions.
The algorithm is based on velocity continuation, that migrate the data multiple times with a different background velocity. After that migration steps, it measures the focusing of the diffraction hyperbolas using local varimax measure. The velocities that produce best hyperbolas focusing will have high varimax and will be the optimal ones.
This package is based on the numerical experiment of the Madagascar reproducible paper Post-stack velocity analysis by separation and imaging of seismic diffractions
- v1.0 (Beta - In progress)
- v1.0 (Beta - In progress)
- The diffractionSimulator programs are designed for the Madagascar seismic processing package. In order to use them, you should install the actual Madagascar stable version.
- Follow the steps in the Installation section of our README to add the programs in the current version of your Madagascar package.
