OpendTect to operate on Wacom’s leading pen tablets, enabling interpreters to interact directly with the tablet in the editing and visualization processes.

Houston, Texas USA, 11 April 2011. dGB Earth Sciences, the leading provider of open source seismic interpretation software to the oil & gas industry, today announced the launch of the full version of its new OpendTect 4.2 software. The new version can be downloaded at www.opendtect.org and follows the launch of a beta version earlier this year.

In addition, dGB has also teamed up with Japanese company, Wacom, the world's leading manufacturer of interactive pen displays, and digital interface solutions, to enable seismic interpreters to use the new software in an interactive and graphics-focused environment where they can interact directly with the tablet.

OpendTect 4.2 comes with new HorizonCube and Well Correlation plugins, as well as new interpretation, editing and visualization features. Benefits include:

• A significant increase in the number and density of mapped horizons through the HorizonCube plugin, resulting in low frequency model building with a greater number of horizons and more accurate inversion results, geologically sound rock-property predictions, a realistic geologic history and well correlations, and more geological information from seismic than ever before.
  
  
• A well correlation tool with a new stratigraphic framework and interactive viewer from which users can correlate and update well markers and horizons.
  
  
• The latest in visualization, editing and data integration features. Through Wacom’s interactive pen display technology, seismic interpreters can interact directly with the tablet to draw faults, horizons, bodies and interpretive features.

“If you’re tired with picking horizons, want to work more effectively with the structure of your seismic data, and would like a clearer insight into your data’s depositional history, then OpendTect 4.2 is definitely the software for you,” said Paul de Groot, President & CEO of dGB Earth Sciences.

“Through our highly innovative HorizonCube plugin and the intuitive graphics-based workflow we have developed with Wacom, seismic interpreters will be able to reap the full benefits of knowing the complete structure of their reservoir data and will be able to generate more high-value geological information from seismic than ever before.”

The HorizonCube plugin is an advance on OpendTect’s current SSIS (Sequence Stratigraphic Interpretation System) plugin and consists of a dense set of correlated 3D stratigraphic surfaces. A second generation 3D chronostratigraphy auto-tracker algorithm tracks the dip/azimuth field to generate horizons. All tracked events are assigned a relative geological age, with a corresponding colour, with the interactive slider used to add or remove chronostratigraphic events. The Well Correlation plugin includes a new stratigraphic framework and interactive viewer from which users can correlate and update well markers and horizons.

Other new features in OpendTect 4.2 include significant new cross plotting features, including cross-plot colour coding and the ability to create Probability Density Functions (PDFs) in the cross plot domain to create rock property probability volumes; an enhanced 2D Viewer with added tree, horizon and fault tracking capabilities; new directional lighting capabilities to highlight geological objects; and the ability to post OpendTect 4.2 data in Google Earth.

About dGB Earth Sciences

dGB Earth Sciences, a privately owned company based in the Netherlands, has been providing seismic interpretation solutions to the oil and gas industry since 1995. Current customers include Anadarko, BG, DetNorske, Ecopetrol, ENI, Marathon, Petrobras, Petrochina, Petronas, Saudi Aramco, Sinopec, Statoil, and Wintershall among others.

dGB’s flagship seismic interpretation solution, OpendTect, is the only available open source seismic interpretation platform used in the oil & gas industry today, allowing the visualization and interpretation of multi-volume seismic data. OpendTect, which is available at no cost under the GNU GPL license, provides sophisticated interactive attribute analysis.

dGB and its partners have also developed a wide variety of commercial plugins for customers (companies are also encouraged to develop their own customised plugins). These include plugins relating to attribute and processing analysis, sequence stratigraphy, fluid migration, rock property predictions, and velocity modelling. Partners that have also developed commercial plugins of OpendTect include ARK CLS, Earthworks, and Geokinetics. A full list of commercial plugins can be found at www.dgbes.com.
