More Than a Button: The Engineering Philosophy Behind OpendTect
- Written by: Marieke van Hout
To mark our 30th anniversary, I invited former dGB Earth Sciences CTO and long-time OpendTect user Friso Brouwer to share a few words about his experience with the software. Here's what he had to say:
As a former employee and current user of their software, my friends at dGB Earth Sciences asked me to write something to celebrate their 30th birthday. They requested a short reflection on OpendTect—what I like about it.
The challenge? Keep it to just half a page. That’s a bit of a problem, of course, because there’s so much to like about OpendTect. But here, I’ll focus on one thing that has always made my work more enjoyable.

OpendTect webinar: New AVO Formulation and Advances in Bayesian Inversion with the LTrace Bayesian Linear Inversion 'BLI' Plugin
- Written by: Marieke van Hout
📅 Free webinar | 18 September | 🕓 4 PM CET
Following the overwhelming response to our recent post on the new AVO formulation in BLI plugin, we've invited Dr. Leandro Passos de Figueiredo from LTrace Geosciences to host a special webinar on this exciting development and other updates in the LTrace BLI plugin.
At dGB Earth Sciences, we see BLI as a game-changer. It’s one of the most user-friendly and cost-effective solutions on the market for generating acoustic impedance, shear impedance, density, and predicting lithologies from seismic data. With GPU-accelerated performance, it outpaces comparable QI software, making it a powerful asset in today’s seismic interpretation workflows.

Interpretation Showdown: What is your take?
- Written by: Marieke van Hout
Take a closer look at this interval of interest from our well know F3 Demo dataset, offshore the Netherlands. What do you see?
Years ago, two seasoned geologists—both using this exact same intersection for teaching—gave me two completely different interpretations of the interval you’re looking at. Same data. Different minds. Wildly different conclusions.

New AVO Formulation in OpendTect's BLI (Bayesian Linear Inversion) plugin
- Written by: Marieke van Hout
We are excited to announce a major upgrade in BLI!
Dr. Leandro Passos de Figueiredo and Professor Dr. Dario Grana recently published two works introducing a new AVO approximation in terms of P-impedance and Vp/Vs ratio. One is a conference paper for the EAGE Annual Meeting, and the other is a full article in Geophysics.
This new formulation enhances facies classification when applied to seismic Bayesian inversion. It was derived in response to challenges encountered during facies classification with BLI tests on real data.

LUC (Low Unit Cost) Geothermal Energy – Field Trip to Piesberg Recap
- Written by: Marieke van Hout
Yesterday, we had the opportunity to explore the Piesberg quarry in Germany as part of our ongoing geothermal investigation for the Municipality of Dinkelland (Denekamp). This field trip is a component of the LUC Geothermal Energy project, aimed at identifying cost-effective and sustainable geothermal energy sources in the Twente region.

Transforming 2D seismic data into Pseudo-3D using cutting-edge machine learning techniques
- Written by: Marieke van Hout
For those of you who missed our webinar by David Markus, I am hereby sharing the video.
The session covered a workflow that combines traditional interpolation methods with deep learning to create high-resolution 3D volumes from 2D seismic data.
