HorizonCube

HorizonCube

HorizonCube is an innovative step in seismic interpretation and geologic modeling. It is applicable in most of our modeling and interpretation workflows that are based on the seismic data. It is a technology that is being widely used now-a-days for low frequency model building to do deterministic seismic inversion, sequence stratigraphic interpretation together with an automated wheeler transformation, and not only these but also in reservoir modeling. If you are willing to prepare your first HorizonCube for one of these purposes and you need the step-by-step workflow/guide, then please download the following presentations.

Thalweg Tracker

Thalweg Tracker

This is a seismic facies tracker. By following the path of least resistance, this tool offers you a fantastic new way to find channels as shown in in the example to the right. Please have a look at the Thalweg Tracker video.

How to Visualize in OpendTect

How to visualize in OpendTect

Visualizing the results is almost as important as the results themselves, therefore OpendTect has several advanced visualization options.

How to Crossplot in OpendTect

How to Crossplot in OpendTect

Cross-plot tool enables you to create attribute vs attribute, attributes vs well-logs and well-logs vs well-logs cross-plot. The cross-plot includes many useful functionalities that are very important in seismic data analysis and seismic prediction. The presentation will guide you in steps that how to work with this tool. Moreover, a few general workflows are also presented at the end of the presentation.

Stratal Slicing

Stratal Slicing

Horizon based attribute analysis can reveal sedimentary and structural features, but is limited by the number of tracked horizons. Stratal slicing enables you to quickly analyze all available data, increasing the probability to reveal sedimentary structures.

Fault Enhancement Filtering

Fault Enhancement Filtering

OpendTect has excellent filtering capabilities for general data enhancement or highlighting specific features in the data. The attribute engine contains many pre-defined filters for example the Laplace Filter and Ridge Enhancement Filter (present as a default attribute set). In addition to this the user can develop many custom filters by combining attributes such as the Position, Volume Statistics, Reference Shift and Mathematics attribute. This presentations describes how to make such a custom made filter that alters the seismic volume to enhance fault visibility.

Cluster Processing

It is possible to use a cluster management tool (SLURM for example) for attribute processing in OpendTect. OpendTect distributes a batch process into smaller jobs (which can be submitted to a cluster management tool) and merges the outputs after processing. This feature is available to Linux users only.
