HorizonCube: Visualizing and Extracting Geological Information

By 0

Horizon picking can be time consuming especially if we are dealing with a dense grid of 3D seismic volume. This process becomes more complicated when seismic data is characterized by complex geology. To extract detailed stratigraphic, and structural information, more horizons need to be mapped.

OpendTect’s HorizonCube is a game changer when it comes to mapping dense sets of horizons in a semiautomated technique. Geoscientists can interpret a few key horizons, then use them as bounding stratigraphic events and generate the HorizonCube. Users can take advantage of our advanced data driven inversion tracking approach, in which the algorithm tracks horizons based on seismic dips and amplitude.

The HorizonCube model can be used further to investigate, analyze and extract more geological insights. 3D Slider or Stratal slicing, which is part of the HorizonCube plugin, is a technique that allows geologists / geophysicists not only to visualize HorizonCube events in 3D, but to interpret and extract depocenters, pinchouts, stratigraphic channels, ….etc.

This short video shows HorizonCube results on a data set from Taranaki Basin, New Zealand. Seismic section depicts the complexity of the data, the amount of channel cuts, and other geomorphological features.
