Tips & Tricks How to Create a Good HorizonCube

Tips & Tricks

Please have a look at the video below, in which dGB's dr. Paul de Groot shows you how to create a fantastic Horizon Cube.

'I have done some processing on a survey in Rotterdam to improve the shallow section. In the process I also made a HorizonCube, which I consider to be quite good given the quality of the original input. The trick is in the steering cube. I use CSM steering. The same steering as is used to create TFL and planarity.

These are my processing steps:

  1. Filled the holes (some fiddling in OpendTect)
  2. RMS scaling (OpendTect)
  3. Removed the footprint in the cross-line direction (MGS-Destriping plugin)
  4. Dip-steered Median filter (dip-steering plugin using FFT background 333 median filtered)
  5. Thinned Fault Likelihood attribute (Faults & Fractures plugin; CSM dip-steering default)
  6. CSM Smoothing (Faults & Fractures plugin)
  7. HorizonCube (HorizonCube plugin; To constrain the HorizonCube I interpreted two horizons using the unconformity tracker - dip-steering plugin. The steering cube is the CSM steering cube and I used planarity to constrain).'
