Frequency decomposition provides us with the ability to highlight stratigraphic features and nuances that are often obscured in data volumes containing the entire band of recorded frequencies. We color-blend discrete frequencies to produce highly-informative RGB volumes.
Additional volumes are then added to the blend as shown in the upper panels where dip and instantaneous-phase volumes are blended with the original RGB volume.
We use an interactive polygon tool to select voxels across features we identify as representing distinct seismic facies units. Algorithms search for, and color code, all voxels within the 3D seismic volume that satisfy the blended voxel values within the original polygon. The final result is a fully-classified 3D seismic facies volume which can be viewed in a variety of 2D-line or 3D-cube displays, or extracted along horizons.
