Diffraction energy is a natural carrier of small scale subsurface information such as small scale faults, small heterogeneities, pinchouts and fractures. This type of energy is acquired in standard acquisition, but is largely lost during standard processing, because most imaging algorithms are biased against this type of energy, and they fail to separate the different wavefields during the summation process.
In this presentation we show how Paradigm retains and stores the different wavefields along full-azimuth directional angle gathers following depth migration in EarthStudy 360. We further show the different stacking options that this innovative technology supports in order to generate two different types of stacks, specular weighted and diffraction energy, with the aim of providing interpreters with valuable information that will increase confidence in their interpretation.
Specular reflection stacks are high-quality stacks used to emphasize and interpret major continuous events and major discontinuities. On the other hand, diffraction stacks can be used to interpret and delineate high-resolution subsurface stratigraphic and structural small scale features.
We also show how these two valuable deliverables can be blended and further used to complement the standard poststack, attribute-oriented interpretation approach which is in widespread use in the industry.
