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.

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.

This year marks dGB’s 30th birthday🎉—a perfect moment to reflect on where it all began.

Written by: Marieke van Hout

Our journey started in the early 1990s when dGB founders (Paul de Groot and Bert Bril) worked for TNO on a research project involving Neural Networks and stochastic pseudo-wells. The successful project led to the start of dGB in 1995.

Creating labels for supervised geoscience applications

Written by: Marieke van Hout

Supervised Learning is learning by example. It requires a training set with examples of input data tied to known output. The process of linking input to output is called "labeling".

In OpendTect, we support four key labeling methods for applications involving seismic and well data:

OpendTect v7.0.3 includes the first release of the AWS plugin

Written by: Nanne Hemstra

As mentioned in last week's LinkedIn post, OpendTect v7.0.3 includes the first release of the AWS plugin. This plugin enables users not only to import from and export to S3 storage, but also to stream seismic data directly into OpendTect. Running OpendTect from an EC2 instance gives obviously the best performance, but all functionality works on premise as well.

How to Visualize Amplitude Anomaly in 3D Using Spectral Decomposition and RGB Attribute

Written by: Hesham Refayee

Spectral decomposition and RGB(A) blending is not only useful for studying sub-seismic resolution stratigraphic features, but can be a great asset to highlight potential bright (spot) amplitude anomalies.

Can AI Outshine Human Expertise in Seismic Analysis?

Written by: Marieke van Hout

Vulcania Energy, on behalf of MEPC, recently harnessed OpendTect's AI-based fault interpretation to supercharge seismic analysis in an offshore West African field.

Within this reservoir lie complex carbonate turbiditic deposits, molded by gravity's touch, presenting a captivating challenge for both human experts and AI.
