Processing & Imaging: Depth Velocity Model Building and Depth Imaging using Aspen GeoDepth 2D

In this course users learn how to create an initial interval velocity model, perform depth imaging, and update the velocity model using GeoDepth 2D. Students first build an initial grid-based
velocity section with Constrained Velocity Inversion (CVI), run 2D Kirchhoff Prestack Depth Migration, and then update the depth/velocity model with 2D Grid Tomography. Students are also taught how to
create a horizon-based interval velocity section using Coherency Inversion Analysis and normal incidence ray migration, and to update the depth/velocity model with tomography. Students also learn
how to run 2D Grid Tomography in multi-2D line mode, and how to perform residual moveout analysis in vertical mode and use CVI to update interval velocity sections.

Audience:

New GeoDepth users, geophysicists
