Part 4 – Automatic Fault Plane Extraction
This is the fourth post in our series on fault plane interpretation in OpendTect. In Part 1, we looked at pre-processing and visualization of fault attributes. This was followed by manual interpretation on a plane-by-plane basis and by the standard workflow of picking sticks first and creating planes thereafter.

Part 3 – Building Fault Planes from Manually Picked Fault Sticks in OpendTect
In Part 1, we looked at why cleaning up your data and visualizing fault attributes are essential steps in structural interpretation studies. In Part 2, we showcased manual interpretation on a plane-by-plane basis.
Now in Part 3, we dive deeper into manual interpretation of faults and describe the most common method: From unsorted fault sticks ➜ to fault planes.

Part 2 – Manual Fault-Plane Interpretation with OpendTect
In last week's post, we illustrated why cleaning up your seismic data and visualizing faults are crucial first steps in any fault-interpretation workflow.
Now, in Part 2, we move into the hands-on stage: manually picking fault sticks and constructing a fault plane in OpendTect to build a geologically sound structural framework. This can be done in two ways: either on a plane-by-plane basis, or by picking and grouping afterwards.

Fault Interpretation Workflow – Post 1/4: Pre-Processing & Filtering
Over the next four weeks, I’ll be sharing fault interpretation and extraction workflows in OpendTect.
Fault interpretation typically begins with Pre-processing, where we condition the seismic data to improve fault visibility and reduce noise. This is followed by visualizing fault attributes (See the slider for examples of filters and attributes).

More Than a Button: The Engineering Philosophy Behind OpendTect

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
- Details
- 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?

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.
