Dear OpendTect Users,
We have made a patch release for our latest stable version: OpendTect 6.6.10, which is now available for installation/update..
XGBoost NPHI Prediction
- Written by: Paul de Groot
In today’s post we show how Machine Learning can be used to predict a missing log. The model is called XGBoost (eXtreme Gradient Boosting). This is an extremely fast ensemble technique in which the overall performance of a base model is improved through boosting.
Finding Hydrocarbons with OpendTect's Fluid Contact Finder and Chimney Cube
- Written by: Paul de Groot
Today, we show an example of how to de-risk an exploration prospect using OpendTect’s Fluid Contact Finder (FCF) and Machine Learning plugins.
FCF is a tool to enhance hydrocarbon-induced seismic amplitude anomalies. The idea is simple: all seismic traces lying on the same (depth-)contour of a hydrocarbon-filled structure are expected to encounter the same hydrocarbon column length. In other words, the seismic response will be affected by hydrocarbon-fill in a similar manner. Stacking all traces lying in the same contour interval thus enhances the hydro-carbon effect (the anomaly) while cancelling all other effects (noise and lithological differences). The result of a FCF analysis is presented in the form of a panel of stacked traces organized in contour intervals. Step-changes in amplitude response indicate changes in fluid-fill. Another useful output of FCF analysis is a volume of FCF stacked traces to display amplitude maps of FCF-enhanced anomalies

Carbonate Buildup Interpretation
- Written by: Paul de Groot
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.
Seismic Interpretation Services
- Written by: Paul de Groot
Next to developing OpendTect we also offer advanced seismic interpretation services. Our experts have worked on data sets from around the globe. We have extensive experience in hydrocarbon exploration, field development, time-lapse monitoring, unconventional plays and geothermal studies.
OpendTect patch release 6.6.9
- Written by: Arnaud Huck
Dear OpendTect Users,
We have made a patch release for our latest stable version: OpendTect 6.6.9, which is now available for installation/update. We are proud to announce that this release is the first one fully certified by Red Hat.
Improving interpretability with Machine Learning
- Written by: Paul de Groot
Today, we show another great example of how you can quickly improve the interpretability of seismic data by applying a trained Machine Learning model.
DeSmile is one the models from Lundin-GeoLab (nowadays AkerBP) that is available in OpendTect’s growing library of trained ML models
OpendTect is now STL compatible thanks to BGE sponsoring
- Written by: Marieke van Hout
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

Upcoming Price Increase
- Written by: Paul de Groot
We’ve held our prices pretty much constant for a considerable time now but due to spiraling inflation we will be increasing our prices by 10% in the new year.
The updated prices will allow us to maintain and improve our standards for excellence. We will keep pushing the boundaries of technology, improving OpendTect's performance and support, so that we can continue to give you the very best value for money.
