dGB Earth Sciences Offers Free Seismic Interpretation System

September 3, 2009 at 3:15 am Leave a comment

dGB Earth Sciences announced that OpendTect is now a completely free seismic interpretation system. The release of Version 4.0 of OpendTect supports all functionalities needed in seismic interpretation projects. Because the software is open source, it can be used at no cost as dGB has changed its licensing policy.

            Henceforth OpendTect is released under a triple licensing strategy:

  • Under the GNU / GPL license – Free of charge even for commercial use;
  • Under a commercial license – Enables the user to extend the system with closed-source commercial plug-ins that can either be purchased or leased; and
  • Under an academic license – Universities can get free licenses for OpendTect and commercial plug-ins for R&D and educational purposes.

            This new release of OpendTect includes a large number of new features and improvements to the previous version, which included powerful attribute engine and spectral decomposition, horizon tracking and 2D and 3D visualization. Version 4.0 now includes a synthetic-to-seismic well tie module, a SEGY-wizard, pre-stack AVO attribute computation and Time-to-Depth conversion. Other improvements include an updated step-wise horizon tracker and an enhanced cross-plot functionality.

            Several of the commercial plug-ins have been improved, as well. SSIS, dGB’s flagship product for sequence stratigraphic interpretation, now features a new workflow for the analysis of grids of 2D lines. The multi-2D workflow can be applied in faulted areas on 2D and 3D seismic data.

            ArkCls and partner Visual Technology Services have released a new plug-in PDF3D that captures and saves a 3D OpendTect scene in PDF format, which can be opened in the latest free Adobe Acrobat Reader, which supports 3D visualization. Here the user can zoom, rotate, change transparencies and toggle elements on and off. PDF3D is bound to change the way in which E&P work is reported to management, colleagues and partners.

            Also new by Earthworks and ArkCls is a Connection plug-in that allows bodies to be grown from one or more seed points. This plug-in can be used to analyze the results of a stochastic impedance inversion run, for example.

            Paul de Groot, President & CEO of dGB Earth Sciences, said: “This new release is the result of many years of hard work by our dedicated team in close cooperation with ArkCls, Earthworks and Geokinetics with the support of many E&P companies. We are glad that we can now offer this complete and high-level seismic interpretation system for free to the geophysical community. Why would anyone still pay for seismic interpretation software, when the same features can be had for free? Better spend your budget on the advanced interpretation techniques of the OpendTect plug-ins, which really add value to your data.”
