EarthStudy 3D Illumination is an interactive tool that facilitates effective quality control of subsurface imaging. It is dedicated to deciphering the capacity of a given acquisition to illuminate the subsurface.

Features:

• Flexible data input for model building and model changes
• CRP ray tracing for building a comprehensive illumination database (CRP ray time, CRP ray coordinates, incidence angles, reflected angles, surface azimuth, inline and crossline displacement, geometric spreading, etc.)
• A flexible geometry filter which fits the illumination results into the acquisition geometry
• Maps and interactive ray tracing for QC and analysis
• Isotropic and anisotropic illumination
• Offset or angle domain ray

Analysis of the illumination results serves several purposes:

• As a tool to assess the quality of Pre Stack Depth Migration (PSDM) by performing a thorough illumination of the supplied velocity model and correlation of the results to the seismic data images.
• For help in determining the migration parameters that will yield optimal imaging results (e.g. help in setting aperture).
• For help in survey design by checking how different geometries illuminate a given model. Such an analysis can generate an optimum geometry for imaging a specific target.
