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).

- 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.

With over 30 years of experience in Machine Learning, dGB Earth Sciences continues to innovate in the field of seismic reservoir characterization.
Today, we take a trip down memory lane to showcase our journey and highlight our latest breakthroughs.
Carbonate Buildup Interpretation

In seismic sequence stratigraphic studies, we analyze seismic reflection patterns in the context of a chronostratigraphic framework. In OpendTect, such frameworks are defined by a HorizonCube, which consists of a dense set of horizons representing Relative Geologic Time. The SSIS (Sequence Stratigraphic Interpretation System) plugin is an add-on that uses HorizonCube input to decompose depositional systems over geologic time.

Our latest OpendTect v6.6.8 supports STL format. This is a format used in the Computer Aided Design industry to design 3D objects. It is used in the Mining industry to show subsurface constructions such as mines. A nice feature (not shown) in OpendTect is that you can display attributes on the surface of the 3D body. For example displaying fault attributes would show where faults are intersecting the structure
