Machine Learning Workflows - Seismic Inversion using AI - Machine Driven Seismic Inversion Workflow
- Written by: Paul de Groot
Today, in our series on OpendTect Machine Learning workflows, we show a workflow for rock property prediction using real wells.
This workflow has many variations. You can train on real or synthetic seismic data to predict well log properties of interest.
Machine Learning Workflows - De-risking charge and seal issues with AI - Neural Network Chimney Cube
- Written by: Paul de Groot
Today, in our series on Machine Learning Workflows, we go back to the origins of the OpendTect Machine Learning platform. OpendTect started life as a neural network-based seismic pattern recognition and attribute processing system. The primary goal of the original system was to create Chimney Cubes for fluid migration path interpretation. The software was used for geohazard interpretation and for de-risking hydrocarbon charge and seal problems.
The video shows a chimney interpretation study in the Gulf of Mexico by Roar Heggland of Equinor.

Machine Learning Workflows - Fast and Simple Seismic Facies Analysis - 3D UVQ Waveform Segmentation
- Written by: Paul de Groot
OpendTect Machine Learning supports supervised and unsupervised workflows for seismic facies analysis.
Today’s post discusses an unsupervised workflow. The 3D UVQ Waveform Segmentation workflow is the 3D variant of the Quick UVQ workflow that we discussed earlier in this series on OpendTect ML workflows. In Quick UVQ we segment (cluster) seismic waveforms (trace segments) around a mapped horizon into a user-defined number of segments. A typical number of segments in Quick UVQ is 10.

Machine Learning Workflows - Using AI for Salt Detection
- Written by: Paul de Groot
This is the second post in our series on OpendTect Machine Learning workflows. This time we show how to extract a salt body from 3D seismic. The ML workflow is called “Seismic Image Segmentation.” We train a 2D Unet (128x128 samples) to transform a seismic image into an image with values between 0 (no salt) and 1 (salt). The labels for training the Unet are created from interpretations of salt boundaries on a few sections. The trained Unet generates a new volume with values between 0 and 1 from which a 3D salt body is extracted.
