OpendTect

OpendTect is an open source seismic interpretation software system for processing, visualizing and interpreting multi-volume seismic data, and for fast-track development of innovative interpretation tools. Optionally OpendTect can be extended with (closed source) commercial plugins.

GNU GPL

GNU GPL

OpendTect is released under a triple licensing scheme:

GPL (open source)
Commercial (access to commercial plugins)
Academic (free plugins for research only).

The GPL license covers OpendTect. The software is released with its source code (C++), is not protected by a license manager, and can be used by anyone, including for commercial purposes, as long as the user accepts to adhere to the GNU/GPL rules.

2D, 3D, 4D & Prestack

2D, 3D, 4D & Prestack

Analyze 2D, 3D, 4D pre- and post-stack seismic data.

New in v4.4:

Create 3D Volumes from 2D seismic
Interpolate seismic to a new survey geometry
Simple wedge modeling
SEGY header manipulation
3D pre-stack event visualization
Log math & Rock physics library
Checkshot and well log editing
Anisotropic variograms
And much more !!
2D & 3D Viewers

2D & 3D Viewers

Data processing and visualization are rigorously integrated in the OpendTect system. Visualization elements can be moved freely through data space to interactively analyze data from stored volumes, or data that are calculated on-the-fly.

Volume & Stereo

Volume & Stereo

Volume-rendering, stereo viewing and color blending are supported features.

Seismic Attributes

Seismic Attributes

Numerous attributes and filters, math & logic, attributes from attributes are supported in the industry's most powerful attribute engine.

Spectral Decomposition

Spectral Decomposition

Spectral Decomposition is used for imaging and mapping temporal bed thickness and geological discontinuities. Algorithms include FFT and CWT.

Movie-Style Parameter

Movie-Style Parameter

Attribute parameters (frequency, time gate or step out) can be inspected in a movie-style way, to quickly find the optimal settings for your data.

Distributed Computing

Distributed Computing

Heavy processing of large volumes can be carried out in batch mode on multiple machines and on multiple platforms that can be accessed through the network. Interpreters can share surveys.

Horizon Tracking

Horizon Tracking

The horizon tracker supports manual drawing, line tracking and 3D tracking of amplitudes and similarities. Horizons can be tracked on 2D and on 3D seismic data using the 3D scene and/or 2D viewers.

Faults

Faults

Fault planes and fault-sticks sets. Work flows are designed to draw fault sticks, which is very efficient if you work on a Wacom digitizing tablet.

Well-Tie

Well-Tie

The synthetic to seismic well-tie module enables the interpreter to tie wells to seismic:

Synthetic seismogram
Check-shot correction
Additional stretch & squeeze
Updated depth/time model
Statistical wavelet extraction
Deterministic wavelet extraction.
Time to Depth conversion

Time to Depth conversion

Use an existing velocity model, or create one with the new Volume Builder.
Supports: on-the-fly TD conversion of display elements and batch processing of volumes.

Geobodies

Geobodies

Insert an iso-surface in a volume rendered cube and save it as a geobody. Manually draw 3D bodies.

Madagascar Processing

Madagascar Processing

OpendTect has a generic user interface to Madagascar, the open-source software package for geophysical data processing and reproducible numerical experiments.

GMT Mapping

GMT Mapping

Via the link to the open-source GMT package you can create within the OpendTect UI scaled maps of OpendTect results.

Gap Decon

Gap Decon

A multiple removal tool through prediction error filtering. Auto-loaded in OpendTect base. (Sponsored by Addax).

Horizon Attribute

Horizon Attribute

The Horizon attribute allows surface (horizon) data to be combined with cube data for calculations. Auto-loaded in OpendTect base.

Annotations

Annotations

Annotate seismic data with text-boxes, hyperlinks, (lap-out) arrows, and images. Auto-loaded in OpendTect base. (Developed as part of OpendTect SSIS; sponsored by Shell, BG-group, Statoil, TNO).

MatchDelta

MatchDelta

Trace cross-equalization functionality that is used to correct small misalignments in 3D seismic volumes prior to further analysis. It is typically used to align time-lapse seismic data, multi-azimuth stacks or angle stacks (Residual NMO correction). Auto-loaded in OpendTect base.
