Local dip and azimuth at each seismic sample

The dip-steering plugin allows you to create and use "steering cubes". A steering cube contains the local dip and azimuth of seismic events, at every sample position. The cube is used for:

  • Structurally oriented filtering (e.g. dip-steered median filter)
  • Improving multi-trace attributes by extracting attribute input along reflectors (e.g. dip-steered similarity)
    Calculating some unique attributes (e.g. Dip & Azimuth, 3D-curvature, and Dip-Variance)
  • Auto-tracking horizons either single horizons or in a dense set as is done in the HorizonCube.

"Many softwares offer coherency and curvature attributes, but those obtained through OpendTect's dip-steering are really something different."
--Guilherme Fernandes Vazques, Senior Geophysicist, Petrobras

Dip-steering is one of the most popular and most widely used plugins in the suite of OpendTect software tools. In all service projects conducted by dGB the first step after data loading is the creation of a steering cube. This cube is then used to enhance the input seismic data e.g. by removing random noise with a dip-steered median filter, or by drastically sharpening faults with a dip-steered fault enhancement filter. Such steps improve all subsequent work like horizon tracking and attribute analysis.

The Dip-Steering plugin is a required plugin for creating (data-driven) HorizonCubes.
