[OpendTect_Users] OpendTect 4.6

[Kristofer Tingdahl]

Dear OpendTect users,

It is a joy to hereby announce the release of OpendTect 4.6. The highlight
of the release is SynthRock <http://dgbes.com/index.php/synthrock.html>, a
new plugin for forward modelling, synthetic seismic generation, and
inversion (matching synthetics to seismic) and XField
2D<http://dgbes.com/index.php/xfield-2d.html>,
a plugin for potential field modelling and matching. Additionally, there
are hundreds of improvements and new features, of which the important ones
are listed below.

If you have OpendTect 4.4 or later installed, the new version is available
through the installer (available under the Tools-menu). If you do not have
OpendTect 4.4 installed, the new release is available at
http://www.opendtect.org.

Those of you who have commercial plugins may need new license files, which
can be requested from support at dgbes.com

Best regards,


Kristofer Tingdahl

*Highlights in OpendTect*

   - An improved Installer with cross-platform offline installation support
   - Improved, faster 2D displays
   - Angle-based output added to Pre-stack attribute
   - Easier access to the rock-physics library
   - Well log tools now includes a frequency filter tool
   - Format/scaling options available while merging seismic cubes
   - Backus upscaling is used when generating any synthetic seismic dataset
   - Multi-import tools for well tracks, log, markers, and 3D horizons
   ("Bulk import")
   - New 2D pre-stack viewer, including mute and angle gather displays, and
   pre-processing
   - New Time/Depth model manager for wells
   - The Seismic Reference Datum is now a survey setting, it is no longer a
   well attribute
   - Time/Depth converted scenes can be made with a constant velocity or
   velocity gradient
   - Synthetic 1D/2D Probability Density Function (PDF) generator
   - Comments can be written on datasets that have a manager, from that
   data manager
   - 2D log viewer can be used from various new places (well manager, rock
   physics, ...)
   - Utilities in the body manager: merge, region body, combine, switch,
   calculate volume
   - Layers can be manually edited or removed during layer modelling
   - Synthetic datasets (traces and horizons) can be saved and retrieved
   during layer modelling


*Highlights in the plugins*

*SynthRock <http://dgbes.com/index.php/synthrock.html>*

   - First full release of SynthRock featuring a full suite of tools for
   synthetic seismic generation, raytracing, modelling.
   - *Model*: Build wedge models, cross-sections from wells, or Monte-Carlo
   style simulations.
   - *Create*: Pre-Stack synthetic seismic data generation using state of
   the art raytracing, reflectivity calculations, cross-over handling, and
   frequency-domain convolution. Optionally includes generating internal
   multiples and PS conversions.
   - *Modify*: All parameters can be modified on the fly to instantly
   analyse the response on the seismic data.
   - *Analyse*: Perform fluid replacements draw conclusions about your
   reservoir.
   - *Match* the synthetic data to your real-world data and invert to rock
   property probabilies without the need for acoustic, or elastic inversion.

*XField 2D <http://dgbes.com/index.php/xfield-2d.html>*

   - New plugin from ARKeX with a powerful integrated potential fields
   modelling.

*HorizonCube <http://dgbes.com/index.php/horizoncube.html>*

   - HorizonCube editor has 2D support along with algorithm improvements
   for 3D.
   - New HorizonCube attributes: Polar dip, Event curvature and QC
   attribute.
   - Introducing HorizonCube Data objects to store attribute data along
   HorizonCube events which can be displayed in 3D slider.
   - Possibility to add more iterations to 2D HorizonCube.
   - HorizonCube within bodies.
   - An improved horizon-fault trimming tool with multiple gridding options.

*SSIS <http://dgbes.com/index.php/ssis.html>*

   - Random line display in Wheeler scene.
   - New depositional models (Channel stages and Stratal packages) added to
   the library.
   - Optional AGT (Absolute Geological time) annotations available in
   Wheeler scene displays.
   - Statistical curve display and RGT (Relative Geological Time)
   annotations added to the Systems Tract interpretation window.

*Dip Steering <http://dgbes.com/index.php/dip-steering.html>*

   - New dip-steered gridding algorithm to grid sparsely interpreted
   horizons along seismic events.

*Well Correlation Panel<http://dgbes.com/index.php/well-correlation-panel.html>
*

   - Various improvements in display
