Create volumes of Intercept and Gradient from gathers in real-time. Because these are complete volumes, you can use them like any other: view them along arbitrary lines or time/depth slices; in stratigraphically flattened space; or draped on a horizon, to name a few.
Left: near stack; Centre: far stack
Right: stack rotation of -62 degrees, highlighting a fluid effect in a sand wedge not obvious on the input angle stacks
AVA Stack Rotation is DUG’s implementation of Extended Elastic Impedance (EEI). EEI can be defined as a constant angle projection of seismic data, designed to help discriminate between different AVA responses.
Different stack rotations or weighting functions can optimally enhance or suppress certain types of AVA. One of the many things you can learn from the Rock module is which rotation angle should highlight specific fluid and lithology effects.
