High-Resolution 3D Waveform Segmentation
- Written by: Paul de Groot
In April 2022, Friso Brouwer of I^3 GEO, conducted an OpendTect webinar in which he showed how high-resolution 3D waveform segmentation can be used for quick geomorphological analysis.
In this post, we show another application of Friso’s workflow. We use the Delft survey, which is freely available from TerraNubis, our cloud portal. Delft is one of several free projects that do not check for license keys, meaning you can run OpendTect Pro and commercial plugins on this dataset.

OpendTect Pro and Petrel - a direct and seamless connection
- Written by: Marieke van Hout
Free webinar Thursday 25 August - 4pm CET
In this webinar we will demonstrate how you can use OpendTect functionality directly in Petrel or how you can copy data across if you don't want to tie the Petrel license.

Machine Learning: Lundin GeoLab SimpleDenoise
- Written by: Marieke van Hout
This week we want to show you an example of the 4th Lundin model 'Lundin_GeoLab_SimpleDenoise". We believe this model is applicable to almost all datasets. Unlike the AJAX model, the SimpleDenoise model preserves the amplitude - frequency content. It only removes random noise.
AJAX, an ML model to enhance the visual quality and interpretability of 3D seismic
- Written by: Marieke van Hout
This is the third and last post in our series on trained Machine Learning models developed by Lundin GeoLab that are released in OpendTect’s Machine Learning library. Two weeks ago, we presented SimpleHmult, a model to attenuate horizontal multiples. In last week’s post we showed an example of the application of Desmile, a model to remove migration smiles.

Desmile; another pearl in OpendTect’s library of pre-trained Machine Learning models
- Written by: Marieke van Hout
Last week we proudly announced the release of four stunning, pre-trained models from Lundin GeoLab in OpendTect’s Machine Learning solution. In last week’s blog post, we showed an example of one of these models: SimpleHmult, a 3D Unet model that attenuates horizontal multiples.

Sharing Trained Machine Learning Models is Redefining our Modus Operandi
- Written by: Marieke van Hout
As of version 6.6.8, OpendTect’s library of pre-trained models boasts 4 spectaculair seismic enhancement models developed by Lundin’s GeoLab R&D group:
- Desmile: This model removes steeply dipping noise and smile artefacts
- SimpleHmult: Attenuates horizontal multiples
- AJAX: Enhances the visual quality and interpretability
- SimpleDeNoise: Removes “salt & pepper / jitter” noise.
