Depth Imaging vs. Diffraction Imaging
Generic depth imaging improves reflected energies, while seismic diffraction imaging reduces them. In fact, the goal of diffraction imaging is to scale down the reflected energies, within limits. Why do this? Because by reducing the reflected energies, as best as possible, the diffraction results reveal subtle features that are below seismic resolution from reflected energies. As a rule of thumb, if the spatial extent is less than 1/4 wavelength, reflected energy cannot resolve the target.
Examples of geological features that produce such energy scattering include salt/sediment interfaces, subtle faults, fractures, geobody edges, fluid boundaries, and other types of traps and discontinuities.
In-Depth has developed an advanced Diffraction Imaging Analysis (DIA) process that can reveal subtle geological features that common seismic reflection techniques simply cannot.
