GeoTeric Release Notes

2018.2 - 7th January 2019 - Major Release

The 2018.2 release from GeoTeric provides you with enhanced functionality and an improved user interface.  Our comprehensive 2018.2 release notes and bug fixes are available to download here.

2018.1.2 - 13th August 2018 - Interim Release

GeoTeric 2018.1.2

The latest GeoTeric patch contains extensions to our recently released Validate module as well as to the rest of the application.

Wedge Model in Validate

  • Create a wedge model tied to well markers or independently placed anywhere in the data.
  • All aspects of the wedge are adjustable.
  • Go directly to the well on either axis for easy navigation.
  • Variable Density displays Tuning Curve.
  • Interactive wedge thickness display beside cursor, so a user can tell what thickness each colour represents.


Arbitrary Lines 

In the latest version you can also use an Arbitrary Line as an input for your model, allowing you to validate the data between your wells.

Create models based entirely on your well log data

  • Rock Properties can now be extracted automatically from any wells intersecting your model, and propagated based on the layer boundaries drawn in the model, so there’s no need to define rock properties for each region any more:


  • When there are multiple wells in your model, the rock properties will be transitioned between them but will always honour the data exactly at each well’s position.
  • Validate now displays calculated rock properties (AI, SI, Vp/Vs, Poisson’s Ratio) for any layer, as well as Vp, Vs and Density when extracted from the well logs.

Other enhancements/bugs fixed in this patch:

  • We have added wells in more windows:

    • Wells in base map, either displayed as intersection or top location.
    • Wells in the 2D interpretation window.
    • Wells in Spectral Expression, including navigation directly to the well slice.
    • Wells in Noise Expression, including navigation directly to the well slice.


    Interpretation enhancements:

    • Easier to move a slice in the interpretation window, using either slice player, mouse wheel or page up/down shortcut keys.
    • Intersections are now shown on z-slices as well as intersections of z-slices shown on vertical slices in interpretation window.
    • Intersection of fault sticks are now visible in the interpretation window.
    • Easier edit of fault stick: Right-click on a Fault Stick and choose Edit > will bring slice to stick so you can edit it.


    Link for Petrel:

    • Transfer of Fault surfaces both ways.
    • Wells now bring across their UWI if set in Petrel.
    • Transfer logs across to existing wells (when UWI exists or name of well is a direct match).



    • Picking Arbitrary Lines on z-slices in 3D scene.
    • Project tree filtering and search options.
    • Better quality and performance of all overlays and labels where used in Expression tools.


    Bugs resolved: 

    Link for DSG:

    • In some circumstances, the volume transferred across to GeoTeric came in flipped, this has now been resolved.


    Link for Petrel:

    • Well logs transferred across now keep their original name.
    • If users happened to transfer logs that already existed, they now correctly append as an additional log.
    • Some well log colour maps transferred across with the well logs used to throw an error. This is resolved.
    • After transfer of logs into GeoTeric and the user tried to rename one of the logs, some of the others would disappear as well. Resolved.



    • Sometimes when transferring multiple volumes with multiple CRS in one go, the link would crash. Fixed.
    • Transfer of multiple horizon surfaces to Petrel in one go, caused the link to stop working and the user had to re-open it. This has been resolved.
    • Fixed an issue whereby after restarting the Link for Petrel it wouldn’t transfer any horizons. This now works correctly.
    • Fixed an issue whereby duplicated fault sets couldn’t be edited until after project restart.
    • The intersection line in the 2D Interpretation window wasn’t always in the correct place when you swapped the slices - this is now correct.
    • If you tried to delete a well whilst the project manager was open GeoTeric would crash.
    • Changing the source volume in the 2D Slice Viewer when a horizon had been visualised crashed GeoTeric- resolved.
    • Body Labelling process has been fixed.
    • Phase volumes created from the Frequency Decomposition tool sometimes produced a blank result.
    • When using 8bit data and flipping the colour map, the colour table used to stop responding to change. This has been resolved throughout GeoTeric.
    • IFC+ - when viewing over a horizon, the classification is now correct for all data types.
    • IFC+ - classification now updates when you alter the post scale values.

2018.1.1 - 28th June 2018 - Interim Release

GeoTeric 2018.1.1 contains the following enhancements through customer driven feedback:

  • Wells can now be seen in the base map.
  • A scale bar has been added to the base map.
  • The report view header is editable.
  • Multi-select property controls for polygons.
  • Folder control of show/hide all.
  • Right-click adaptive fault - added duplicate button.
  • Removed the Auto and Max Stretch floating point data ability in the Segy loader and Convert process as these don't apply to to this type of data.

Issues resolved in this release:

  • Project Tree: You can now move items from a subfolder into the root folder again.
  • Fixed issue around it, adding items next to the one you clicked on to the scene.
  • Fixes to problems with opacity and data mapping caused by inclusion of well log ribbons in scene.
  • Interpretation Accept function wasn’t working properly for polygons and grid selections in the basemap.


2018.1 - 14th May 2018 - Major Release

GeoTeric 2018.1- Closing the Loop to give a deeper understanding, quicker interpretation workflow and less uncertainty.

Validate – new Module!

Validate has been developed as part of a three-year project with industry partners and is a forward modelling tool that will help you understand what the colors mean in the RGB Blends.

It allows you to Validate your interpretation by:

  • Assessing the uncertainty.
  • Predicting how fluid changes will appear in your data.
  • Understanding what causes the frequency changes in the RGB Blends.

Further new features include:

Improved data management:

Master project – allows multiple users to work from one GeoTeric project without the need to copy in all the seismic data, saving both time and disk space.

Non-seismic data e.g. well data can be loaded into the Master project and distributed across teams to ensure data integrity.

We have also introduced well log templates, assigning each log as they are imported to a template. They can then be centrally managed to ensure a standardized display of logs. The well log manager will ensure you can easily see what logs you have and assign them to the correct template if required. Logs brought across from our third party links will bring the assigned template with them.

You can also select multiple wells and assign mutual properties to them in an easy way, ensuring easy management of multiple wells in the display.

Improved Usability extensions:

Interpretation extensions

  • Polygon control for constrained growth as well as deletion.
  • Improved in-scene interactivity by allowing you to right-click on Adaptive Faults and Horizons for fewer mouse clicks whilst interpreting.
  • Improved surface visualization with a sharper display and more accurate positioning.


Report view - an easy image capture tool incorporating annotation, color tables, scale bars etc.


We have also continued to build on the performance work we did in 2017.2.2 by:

  • Visualization interactivity/performance – slices and volumes in 3D scene – should reach higher resolution faster.
  • Faster horizon cache on projects on network.
  • Improved performance when adding multiple wells to scene.

Issues resolved in this release:

The interpretation lines no longer flicker when zooming into base map.

You are now able to interpret through a polygon in the 3D scene.

Accepting a fault stick now works in all directions again.

When tracking horizon using the graph theory, the height mapped values sometimes broke and produced a red surface.  This has been fixed.

The fault tree project section no longer reshuffles when re-starting GeoTeric.

Spaces are now accepted in project item names.

Several issues around handling of floating point data has been resolved including HDFD, Horizon tracking and GO Semblance attribute.

SEG-Y import and export caused random crashes on Linux - this is now resolved.

Several instances of the colormap compression not working as it should have been resolved. These include:

    • IFC+ - when you had a geobody volume and a color blend.
    • IsoProprotional slicing generated attributes – compressing color map did nothing.
    • As input for opacity controlled process e.g. body labelling – used to throw an error.

Setting the opacity on a blend and render the result in 3D could produce a blank output in some cases.  This is resolved.

Mapping an opacity blend on a horizon now produces correct result.

If you changed the data displayed on a slice from volume data to blend data, the slice was automatically removed from the scene - this is also resolved.

The Time attribute produces correct result even for larger volumes.

Scale bar in the 2D viewer was wrong if window had been resized in certain ways. Fixed.

The Link for Petrel now supports all characters including @ and “”.


2017.2.2 - 30th Nov 2017 - Interim Release

GeoTeric 2017.2.2 – Turbo Charge Your Interpretation

The bulk of the work in the patch is around interactivity performance which can be split into three sections:

  • Horizon rendering performance
    • Performance when data mapping large surfaces is much better.
    • Performance when shifting data mapped horizons is much better.
    • Users are no longer limited by the number of Horizon Points as before and should not need to reduce the number of horizon points in order to visualize the surface.
    • In previous versions, some horizons when mapped with data, turned ‘pink/red’ – this has been resolved and should no longer happen.
  • Expression tools performance
    • Noise & Fault Expression is between x2-x25 faster depending on setup.
    • Spectral Expression is, on average, twice as fast.
    • The best improvement will be seen in the ‘least optimal’ setup e.g. processing a large volume where the ‘data’ required for processing in the Expression tool doesn’t fit into the processing memory and project is accessed across a poor network or to an external USB disk.
    • The least amount of improvement will be seen where the starting conditions were good e.g. local project using a small volume. 
    • Overall, we have reduced the difference in performance seen when running the Expression tools on a project stored locally vs on the network, as well as the differences seen when temp file location being local vs network location.
    • The results seen will vary greatly depending on a variety of factors, incl. volume size vs processing memory settings (GeoTeric option), shape of volume i.e. number of traces, physical location of GeoTeric project, network connectivity, location of temp file directory, RAID setup.

  • General interactivity performance:
    • Changes to the code have halved the start-up time for GeoTeric.
    • General interactivity has been improved. This will be particularly noticeable when adding and removing items to the scene - including slices, volumes, arbitrary lines, color blends and data mapped horizons. Another area of improvement is when switching to data mapped mode for horizon and fault surfaces.
    • Improvements will also be seen when panning through data using slices, arbitrary lines or volumes where the data should reach higher resolution quicker and the scene remains interactive throughout.

Other enhancements/bugs fixed in this patch:

  • The waveform tracker (fill) in Adaptive Horizons now has improved snapping to peak / trough.
  • The histogram will now correctly zoom in when adjusting the color bar compression.
  • Support for NVIDIA Pascal cards on Linux.
  • We have fixed an issue where Horizon interpretation occasionally crashed with a well in the 3D scene.
  • We have fixed a crash caused by exporting a GeoImage in the Linux version.
  • The Dip attribute returned an invalid number in certain floating point volumes, which in turn caused Fault Expression to fail. This has been resolved.
  • Fault Expression: Detect on CMY now always returns a result.
  • In the batch processor, sometimes you weren’t able to edit the name of output volume. This has been resolved.
  • Transferring data following fault sticks to DSG using the Link crashed DSG. This has been resolved.
  • Fixed an issue where the STOIIP calculator sometimes showed the wrong units.

2017.2.1 - 31st Oct 2017 - Interim Release

GeoTeric 2017.2.1 – Adaptive Fault Interpretation with Data Following Fault Surfaces.

With the introduction of data following surfaces, users of GeoTeric 2017.2.1 can now accurately track faults that truly follow their data in just a few clicks. The patent pending approach allows the fault surface to snap to any data- whether this is a single fault attribute, reflectivity or a color blend.


GeoTeric 2017.2.1 also contains the following:

  • We have done a lot of work on improving the responsiveness of GeoTeric when adding and removing items to the 3D scene and when interacting with slices and Arbitrary Lines in the 3D scene.
  • The complete line feature for Adaptive Horizons was not working as expected in 2017.2, meaning users had to track on slice before it worked – this has now been fixed.
  • Changing source volume on slice displayed in the interpretation window sometimes didn’t update the data correctly- resolved.
  • The well correlation panel sometimes crashed when adding seismic track to the view - this has been fixed.
  • Sometimes if user moved off GeoTeric with the cursor, it would get stuck in fault tracking mode and you were unable to end the fault picking.
  • Very rarely, the 3D scene would become visually corrupted when tracking data following sticks - this has been fixed.
  • Exporting a SEG-Y to floating point now automatically defaults scale to none.
  • Noise Expression: when the temp directory is stored on a network drive, the performance is now equal to that of when it’s local.

2017.2 - 28th Sep 2017 - Major Release

GeoTeric 2017.2 continues to expand on our Adaptive Interpretation system by introducing Adaptive Fault Interpretation


Our new Adaptive Faults use Regional Structural Awareness to guide the fault sticks through the data, whilst still allowing the interpreter full control over the end results. Since it’s based on GeoTeric’s patent pending Graph Theory approach it will also show the user different alternative paths as you interpret your data.

Key Features include:

  • Data following fault sticks increase the resolution and precision of structural interpretation.

  • Interpret directly on reflectivity, attributes or blends in 2D or 3D.

  • Automatic preview of surface generation for rapid QC whilst you interpret.

  • Easy editing of fault sticks in a similar way to Adaptive Horizons.

  • Interpret fault sticks on Arbitrary Lines.

Also in the 2017.2 release:

  • Full support for floating point data throughout GeoTeric.

  • Adaptive Horizons can now be tracked on Arbitrary Lines.

  • Well correlation panel now allows you adjust the synthetic in either time or depth domain.

  • Several performance and interactivity issues resolved in order to ensure a smooth interpretation experience.

  • Faster SEG-Y header scan and IsoProportional Slicing export.

  • GeoTeric is now compatible with Petrel 2017.


2017.1 - 22nd June 2017 - Major Release

GeoTeric 2017.1 is our biggest release yet with lots of new functionality. 2017.1 launches our brand new unified seismic interpretation platform with the new Adaptive Horizons, harnessing the power of cognitive decision making.

The new Adaptive Horizons use Regional Structural Awareness, based on a patent pending graph theory approach to guide the tracker through the data whilst still allowing the user full control over the interpretation result. 

When upgrading old projects, any previously interpreted Adaptive Horizons will be converted to the new format automatically.

You can also convert a static Horizon surface that has been imported from a file or via one of the third party links to an Adaptive Horizon for further editing. The new Adaptive Interpretation platform also contains a 2D interpretation and base map window, fully synchronized with the 3D view.

We have also made many general improvements to GeoTeric to enhance the interpretation experience, including:

  • Linked Cursors between all the windows.
  • Easy slice manipulation with playback controls.
  • Automatic Save session - GeoTeric now starts up where you left off.
  • New survey grid in the 3D scene.
  • Extended the surface overlays functionality.
  • Right-click option in the 3D scene on volume to create slices.
  • Right-click option in the 3D scene to Reset probe.
  • Arbitrary Lines can now be moved and edited and the draped data updates on the fly.
    • To move the entire line, simply click on it and drag it.
    • To edit individual points on the Arbitrary Line, right-click on and select Edit line.
    • We have also improved performance and added cursor location reporting.

GeoTeric 2017.1 also contains several extensions for handling well data in GeoTeric:

Well correlation panel

  • Multi well and log display.
  • Correlate your markers.
  • Assign lithologies.
  • Synchronized 3D and 2D edit.
  • Scaled plotting.

Seismic to Well ties

  • Sonic Calibration.
  • Synthetic seismic.
  • Single or multi point stretch and squeeze.
  • User defined Ricker wavelet.

Well cross sections: Right click on any well(s) to draw a section between them. The section can then be draped with any attribute in the standard GeoTeic way. 

Multiple well marker import using a simple ASCII loader.

Further general enhancements:

  • Improved Fault Detect algorithm, where the value has a more direct relation to the confidence level.
  • If the Expression tools can't detect a supported graphic card, they will throw an error.

Extensions and issues resolved with GeoTeric's third party links:

Link for Petrel:

  • Compatible with Petrel 2015 & 2016.
  • Extended CRS handling when transferring wells, faults and polygons.
  • Improved depth to time unit conversion between GeoTeric and Petrel.
  • Scale for volume import now defaults to Auto Scale.

Resolved issues with:

  • If the Petrel project contained lots of volumes, in some circumstances, no volumes appeared in the link UI. This has been resolved. 
  • For some blends, the Z value was modified during transfer - again, this is resolved.
  • We have also changed it so that names with @ no longer throws an error when transferred. 

Link for DecisionSpace

  • Compatible with DSG 10.ep2, ep3 and ep4. 
  • Certified by Landmark to be used with 10 ep.3.
  • All the functionality that was in the previous version of the Link is still there as well.
  • Polygons can now be transferred both ways.

Link for PaleoScan

  • Issues around scaling of floating point data have been resolved.

2016.2.1 - 6th Jan 2017 - Interim Release

New! Link to PaleoScan - allowing closer and faster integration between the two applications. The link allows for:

  • Creation of a new PaleoScan project based on data in GeoTeric.
  • Transfer of volume(s) both ways.
  • Transfer of horizon(s) both ways.
  • Transfer of PaleoScan geological model(s) from PaleoScan to GeoTeric.

Users can now easily scroll through a mapped blend or a volume on several horizons by creating a Horizon Pack. By using the IsoProportional Slicing tool, the user can create iso-conformant surfaces and then scroll through these showing the geology in a stratigraphically conformant manner. 


It’s now easy to switch on multiple horizon overlays by right-clicking on any surface (horizon or fault) and open the Overlay dialog where all the overlays can be managed from one dialog.

Spectral Expression has been extended and now does Spectral Band, passing using either Butterworth, Ormsby, High pass or a Low pass filter.

The wells in the 2D and the IFC+ now also shows the wells as ribbons with same controls - as was introduced for the wells in the 3D scene in 2016.2. 


2016.2 - 30th Sep 2016 - Major Release

GeoTeric 2016.2 continues to improve the user experience by focusing on strengthening the core interpretation functionality. This includes:

Faster performance in the Expression tools allowing you to work interactively with even larger datasets:

  • Fault Expression is up to 6 times faster.
  • Noise Expression is up to 2-3 times faster.
  • Improvement seen will be dependent on data size, hardware and setup.
  • The Expression tools also have Cursor location reporting feature added to help you navigate your volume.

Extended well functionality which includes:

  • Ability to display logs as ribbons and up to three logs simultaneously for each well.
  • A new ‘Well Edit’ table allowing the user to QC the well data, and also to edit wells to remove spurious points, for example.
  • We have improved the handling of datum and depth measurements.
  • The third party links have been extended to allow control over which logs are imported.
  • The third party links also now clearly indicate when the well transfer is finished, preventing the user from accidentally interrupting the transfer.
  • We have resolved several issues whereby the well would cause visualization artefacts.
  • We have also improved the performance so visualizing several wells with or without logs should not affect the overall interactivity of GeoTeric.


Left & Middle: GeoTeric’s new multi log display and improved multi well visualization and performance.

Right: Geobody, fault & horizon interpretation: in GeoTeric.

Improved metrics & Hydrocarbon Calculator:

  • We have introduced further metrics to both Adaptive Geobodies and horizons. These can be found in the properties panel for each item, with the option to display it in the scene for easy snapshots.
  • To complete the Prospect Generation workflow in GeoTeric, we have introduced a STOIIP/GIIP calculator to allow you to get a rough idea of the size of your reservoir. The hydrocarbon calculator can be accessed from the Tools menu, or alternatively, by right-clicking on an Adaptive Geobody or a Horizon in either the project tree or 3D viewer.
  • The ruler in the 3D scene now has a show/hide option for better control when taking screenshots.

GeoTeric is now offered with a modular license option:

  • The modules are: Condition, Reveal, Interpret (which is the core license module) and Classify. For further information on what each module offers, please contact Support.
  • Extended license functionality includes a “use offline” (borrow) feature.
  • We have improved the stability of GeoTeric when temporary interruptions to the license server occur.

Extended editing & transfer of fault sticks:

  • By selecting one or more points in a fault stick, the user can edit their location (either by mouse or keyboard).
  • Users can now delete points when picking Fault Sticks, either by stepping back when an erroneous pick is placed or by coming back later and deleting a misplaced pick.
  • We have also extended the third party links to allow the transfer of fault sticks to and from GeoTeric.

Bug fixes and smaller enhancements include:

    • GeoTeric now fully supports projects with a negative start time or depth, including well data.
    • In the scatterplot tool, we have added a save option, allowing you to compare data trends and determine the most optimal attribute to define the objective.
    • When exporting color blends, there is an option to export a color bar which is compatible with Jason*, allowing you to bring in your blends into Jason. Note: an option to import GeoTeric volumes is available in Jason 9.6.
    • Sometimes when interacting with the project tree in GeoTeric or moving through a volume, GeoTeric would slow down. This is resolved.
    • In GeoTeric 2016.1, the blends sometimes appeared with visual artefacts. This is resolved.
    • Several issues have been resolved around Fault Stick picking including random crashes, faults disappearing, colors being wrong, ability to rename Fault Sets.
    • Fault Trends produced West-aligning faults for volumes orientated in certain way. This has been resolved.
    • Fault Expression sometimes failed to generate a 3D result. This has been resolved.
    • Subset dialog now shows correct volume size.
    • Sometimes the blend wasn’t showing the correct opacity applied. This has been fixed.
    • Now able to rename and delete items which are viewed in the 3D scene.
    • Expression tools crashed if the Z increment was not divisible with extent. This has been resolved.
    • In some circumstances, volumes would be listed multiple times in selection boxes. This has been resolved.
    • When a CMY blend was created using Fault Expression, it appeared in the tree with a red exclamation mark, meaning it appeared invalid. This has been fixed.

2016.1 - 15th Apr 2016 - Major Release

GeoTeric 2016.1 contains the following changes:


  • All 3D processing in GeoTeric is much faster - including the data I/O. Depending on your system, you can reduce time taken from start until you can use the data by 90%.
  • Expression tools have been re-designed to handle larger datasets and have been given a performance boost as well.

In order to achieve the speed improvement, we have changed the file format, meaning there is an upgrade step. For full step by step instructions for the upgrade, please see here.

  • Removed the separate large cache stage so there is only one "green progress bar". A separate display file is created during the creation of the datafile but it's only about 20% of the size of the original datafile.
  • The color blends no longer require caching. Instead, all the blending is now down using the GPU (Note: this has increased the minimum driver version to be more than 340.XX. See here for full details)

Despite having removed the separate Cache stage, the functionality and quality of volumes and blends have remained the same.

Even easier to use:


  • Right-click options for the most commonly used functionality for all items visualized in 3D scene and context sensitive What's Next" option. Intuitive options to make your workflows more streamlined, with fewer mouse clicks. The options include easy access to all the Interpretation objects as well as item specific functionality for that item.
  • Display of color tables in 3D scene (switch on in View menu) as well as improved 2D scale bars.

More technology:

  • Spectral Expression:
  • Ability to save and load your target, original or enhanced spectrum curve, ensuring you are always able to repeat your workflow. There's also improved reporting and means for you to extend Spectral Expression to be used in AVO/4D workflows.
  • You are now able to change the minimum frequency used in the analysis to work with low frequency data including broadband and depth data.
  • For greater repeatability and control, you can now enter the four corner points of your spectrum curve together with the slope of the spectrum.
  • Spectral Expression now supports spectral suppression.
  • Ability to change scale of the curve for improved visibility as well as frequency read outs on values along the 3 curves.
  • Polygon interpretation in the 3D scene, available from Interpretation menu or the new right-click or 'Next Steps'. Polygons can be picked on all items in the scene.
  • You can also change the outline of the polygon from solid line to dashed or dotted as well as fill it in with a varying transparency.
  • Polygon's also display their aerial extent measurements.
  • Polygons can now be transferred across the third party links.
  • Improved Arbitrary Line picking. Accessible from the Interpretation menu or right-click / 'Next Steps' menu.
  • Ability to display color blends on Arbitrary Lines.
  • Now works in the same way as all other picking tools in GeoTeric.
  • Fixed all the issues in the previous version of GeoTeric linked to the Arbitrary lines incl. instability crashes, color map not updating properly etc.
  • Ruler in 3D scene- accessible from Ruler tool bar icon.
  • Opacity Blends can now be used as an interpretation object with both polygons and fault sticks.


  • Well log color maps are now displayed over actual log range and can be reversed.
  • Wells transferred across the Link to DSG now use the TD curve as well.


  • We have optimized the Convert to seismic cube algorithm in the link to Petrel so this is now faster. It also uses less space since it is now always 16 bit. (won’t lose any resolution since it only uses 1024 colors)
  • You can also display our high resolution color blends on 2D slices in GeoTeric.
  • Resolved some instability issues when rendering our high resolution blends on horizon within Petrel (using the Link to Petrel).
  • We have extended the ruler in the 3D scene to have individual interval velocities.
  • Histogram correctly showing for all IFC+ classified 32bit volumes.
  • Resolved issues with starting GeoTeric if projects were no longer available.
