dGB Earth Sciences, the open-source seismic interpretation provider, has teamed up with Geoinfo SRL to bring the latest OpendTect plug-in for petrophysics interpretation.

The Computer Log Analysis Software (CLAS) plug-in will result in improved well-to-seismic ties, the enhanced calibration of seismic attributes to reservoir properties, more robust models and the more accurate interpretation of 3D seismic data.

"This is a major step forward for OpendTect enabling interpreters to combine seismic data with petrophysical data to provide an even more accurate characterisation of the prospective reservoir", said Kristofer Tingdahl CEO of dGB Earth Sciences.

With CLAS, seismic interpreters can edit well logs and generate vital information on oil in place through data on the saturation, clay volume, porosity, lithology and fluid content of the reservoir.

CLAS will also allow net pay to be estimated from seismic attributes and will be able to use dGB's neural networks plug-in to generate accoustic logs. The result will be the building of accurate models and improved acoustic and elastic impedance inversion.

The OpendTect Connector plug-In for Petrel software, developed by ARK CLS using the Ocean* software development framework, will provide the Petrel user community with access to OpendTect’s industry leading commercial plug-ins relating to areas, such as attribute and processing analysis, sequence stratigraphy, fluid migration, rock property predictions and velocity modeling.

3D horizons, including time/depth horizons, and high quality attribute volumes generated by OpendTect, can all be incorporated into Petrel software, enabling users to build robust reservoir models, maximize their geological data, and bridge the gap between seismic quantitative interpretation and more production-focused reservoir models.

In all cases, interpreters will be able to seamlessly export and import seismic data between the Petrel workflow manager and OpendTect with no need to move separate SEG-Y files back and forth between applications as was done previously.

Seismic interpreters will also be able to use Petrel software to access OpendTect’s latest plug-in, HorizonCube, significantly increasing the number and density of mapped horizons and resulting in improved low frequency model building, more accurate inversion results, and geologically sound rock-property predictions.

“This is a milestone moment for OpendTect,” said Paul de Groot, President & CEO of dGB Earth Sciences. “Our link-up with Petrel software will enable interpreters to capitalize on the best features of both systems – the powerful seismic interpretation tools of OpendTect alongside the mainstream interpretation and modeling capabilities of Petrel software.”

“The result will be a seamless workflow from the acquisition and interpretation of seismic through to reservoir modeling and simulation and the reaching out of OpendTect throughout the geology, geoscience and geophysics communities.”

His words were backed up by Adrian Bennetton, Managing Director of ARK CLS:

“One of the key roles ARK CLS plays is in the role of technology facilitator, integrating some of the leading software offerings in geology and geophysics to provide a more complete solution to the operator.”

He continues: “With the OpendTect Connector plug-in for Petrel software, we believe that we have developed a highly effective cross-platform seismic interpretation framework which provides a win-win solution for all parties and, in particular, the geophysics and seismic interpretation industry as a whole.”

Future plug-in connectors with OpendTect and Petrel software are likely to include the absorption of sophisticated well data, such as well header information, time and depth curves, and wireline log data.

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.

ARK CLS has a longstanding relationship with dGB and has developed a number of commercial plug-ins itself for OpendTect. These include plug-ins for Seismic Coloured Inversion (SCI) and Seismic Spectral Blueing (SSB); Workstation Access, which supports the importing and exporting of data to Landmark's SeisWorks®/OpenWorks® and Schlumberger's GeoFrame*-IESX* data stores; and PDF 3D, which allows users to grab a 3D scene in OpendTect and save it in pdf format.

The OpendTect Connector Plug-In for Petrel software is downloadable at Schlumberger’s Ocean store at http://www.ocean.slb.com.
