Structural Imaging


Time proven robust solutions for complex ray path imaging. Imaging structured seismic data is a core strength at Divestco. Experienced geoscience solutions for onshore Time and Depth projects.

Structural Imaging

Time proven robust solutions for complex ray path imaging. Starting with the near surface Tomography model to each step in Structural imaging, we provide optimal resolution of dipping events and velocity models tied to geological dip. 6D Interpolation (SPRINT6D) is specialized for complex datasets requiring angular weighted MWNI.  We offer advanced anisotropic time and depth imaging services. Divestco has proven geophysical experience in rugged terrain and complex geology.

AccuracyRay based single path.Wave based multi paths.
Offset definitionSurface Shot-to-Receiver. Subsurface Shot-to-Image.
Domain- Offset.
- Wavefield can NOT move across offset volumes, but within only.
- Shot.
- Wavefield can move across offsets within the migrated shot volume.
In the presence of multiplesMultiples migrate within the offset volume.Multiples migrate towards near offsets.
CIGs- Variable and coarser offset increments.
- Fewer offset traces.
- AVO friendly.
- Regular and finer offset increments.
- More offset traces.
- More information.
- AVO friendly.
