Salt Dome Interpretation Tool ver 1.0

 

At CeGP, we are conducting research on the automation of seismic interpretation for post-migrated seismic volumes using advanced pattern recognition, machine learning, and human vision system models. The Graphical User Interface (GUI) version 1.0 for visualizing, testing, and benchmarking various algorithms for salt dome delineation is now available to download. This version (v1.0) of the GUI compares different salt dome delineation algorithms.

We seek your feedback and suggestions. You are also welcome to send your salt dome delineation algorithms to include in the GUI for benchmarking, and comparison with other algorithms.

Microseismic Monitoring

Dataset:

We have used the real seismic dataset acquired from the Netherland’s offshore, F3 block in the North Sea, whose size is 24 x 16 km^2 [1]. The seismic volume that contains the salt dome structure has an inline number ranging from #151 to #501, a crossline number ranging from #401 to #701, and a time direction ranging from 1,300ms to 1,848ms sampled every 4ms.

Salient Features of the GUI:

  • Comparison of different salt dome delineation algorithms, which include
    • 2D GoT by Wang et al. [2]
    • 3D GoT by Shafiq et al. [3]
    • 3D Sobel filter by Aqrawi et al. [4]
    • Texture attributes by Berthelot et al. [5]
    • Codebook by Amin et al.
    • Active Contour by Shafiq et al. [6]
  • Visualizing 3D Salt Dome
  • Objective evaluation of the results of different salt dome delineation algorithms
  • Interactive salt dome boundary correction

How to download the salt-dome interpretation tool?
