2026 GSH Spring Symposium
Technology Trends Impacting Geoscience Today and in the Near Future
Overview
As seismic datasets grow in size and complexity, interpreters face increasing challenges in accurately identifying and classifying fault systems. Traditional workflows often require significant manual effort and can be impacted by noise, stratigraphic features, and interpreter bias.
In this presentation, Rocky Roden introduces an integrated machine learning-based workflow designed to enhance fault detection and classification in 3D seismic data. By combining deep learning, advanced attribute analysis, and unsupervised classification techniques, this approach reduces interpretation time while improving the clarity and consistency of fault interpretation.
About the Talk
This workflow begins with seismic data preconditioning, followed by the application of a 3D CNN trained on synthetic datasets to identify fault probability across the volume. While CNN outputs are powerful, they often include non-fault discontinuities such as unconformities and noise.
To address this, image-processing techniques are applied to enhance true fault features and suppress false positives. Fault attributes such as dip and azimuth are then transformed into continuous geodetic components, enabling more effective clustering and classification.
Finally, a self-organizing map (SOM) is used to classify fault components into meaningful groups, allowing interpreters to isolate fault sets by orientation and better understand structural trends within the subsurface.
What You’ll Learn
- How convolutional neural networks (CNNs) can be used to generate high-quality fault probability volumes
- Techniques to enhance fault discontinuities and suppress non-fault artifacts such as noise and stratigraphic edges
- A novel approach to fault parameterization using geodetic fault components
- How self-organizing maps (SOMs) enable automated fault classification and segmentation
- Ways to reduce interpreter bias and accelerate structural interpretation workflows
Why It Matters
By integrating deep learning with advanced seismic attribute analysis, this workflow:
- Improves fault detection accuracy
- Minimizes the impact of noise and stratigraphic artifacts
- Reduces manual interpretation effort
- Provides more consistent and unbiased results
- Enables clearer visualization of complex fault systems
This approach represents a significant step forward in leveraging machine learning to support faster, more reliable seismic interpretation.
