Publish to Seequent Evo

Use the Publish to Seequent Evo option (geogxnet.dll(Geosoft.GX.Evo.PublishObjects;Run)*) from the Seequent Evo menu to publish geoscience data from your Oasis montaj project to a Seequent Evo workspace. Seequent Evo workspaces serve as storage areas where you can publish, view, manage, and share geoscience data across multidisciplinary teams.

You can also access this option from the context menu of individual datasets selected in the Project Explorer. However, it will not be available for data types that are not currently supported by Seequent Evo.

This option is unavailable if you are not signed in with your Bentley account or if your subscription does not include Seequent Evo entitlements. Additionally, it will be disabled if you are not connected to a Seequent Evo Instance or you are not assigned to a workspace within the current instance.

To use this feature, ensure that you are signed in and connected to a Seequent Evo instance within your Oasis montaj project. Go to Seequent Evo to create a workspace in the selected instance. You can also have permission to publish data to other users' workspaces in the same instance. For further details, refer to Oasis montaj Integration with Seequent Evo.

Publish to Seequent Evo - dialog options

The dialog presents datasets added to your project in a tree-like structure. They are listed in alphanumeric order and grouped by status (see below), with further organization by dataset type within each category.

Unsupported formats will either be absent from the list or appear as disabled. Refer to the Application Notes below for more details.

When the dialog is opened from the Project Explorer using the context menu for one or multiple selected datasets, those datasets will be automatically checked in the list.

Select a workspace:

Workspace

The Workspace list displays all workspaces within the currently connected Seequent Evo instance, sorted alphanumerically. Other users within the same instance can share workspaces with you, and any shared workspaces will be added to the list. By default, the first available workspace is selected.

Use the drop-down list to select the workspace where you want to publish your data.

Your selection will be retained after publishing, and the workspace will be automatically selected when you reopen the dialog within the same project.

Script Parameter: PUBLISH_TO_EVO.WORKSPACE_VALUE
Filter your selection by dataset name, object data type, last modification date, or the most recent published date in Seequent Evo:

Your filter criteria (selected filter and search string) will be retained and automatically applied when switching workspaces or reopening the dialog after publishing.

Filter By:

You can filter the list by:

Search Objects

Enter a keyword or search term based on the selected filter. As you type, the list updates dynamically.

If items are selected in the tree view, the number of filtered-out objects appears in parentheses and updates in real time as search criteria change. Clearing the filter removes the text and the count in parentheses.

Script Parameter: PUBLISH_TO_EVO.FILTER_VALUE
Select the data you wish to publish:

Click a column header to sort the list of datasets within each category in ascending or descending order.

Datasets are grouped based on their status and reference to the selected workspace. The tree structure includes the following categories and subcategories:

New and Changed

New: These are datasets that have not yet been published. They are indicated by the absence of a timestamp in the Last Updated in Seequent Evo field. Publishing a new dataset will create a geoscience object in the selected Seequent Evo workspace and update the date field with a local timestamp.

Changed: These are published datasets that have been modified since the last publishing. The modified date (Last Local Modification) differs from the published date (Last Updated in Seequent Evo). Publishing a modified dataset will generate a new version of the existing geoscience object in the Seequent Evo workspace, updating the timestamp (local time) in both date fields.

Unchanged

Unchanged: These are published datasets that have not been modified since the last publishing. The modified date (Last Local Modification) matches the published date (Last Updated in Seequent Evo). Selecting an unchanged dataset for publishing will create a new version of the existing geoscience object in Seequent Evo and update the timestamp (local time) in both date fields.

Grid, Voxel, etc.

Each category will include subcategories for supported dataset types, such as Grid, Voxel, etc., provided there is at least one dataset of that type in the current project and its status matches the category.

Disabled Datasets

Some datasets in the list may not be enabled. A dataset is disabled (greyed out and non-selectable) in the following instances:

  • Published to another workspace: A dataset can only be published to one workspace per instance. If it has already been published elsewhere, it will remain disabled in the currently selected workspace.
  • Duplicate name in the current workspace: If an object with the same name as the dataset is already published (e.g., from another Oasis montaj session or application) in the workspace, the dataset will be disabled. To publish it, select a different workspace from the Workspace list.
  • Unsupported Format: The dataset format is not supported. See the Application Notes below for details on supported datasets and unsupported formats.

Hovering over a disabled dataset will display an informational tooltip.

Selection State

Expand/Collapse:: Click the chevron icon next to a category or subcategory to expand or collapse the desired node.

Checkbox Toggle: The checkbox at the root node level of each category/subcategory acts as a selection toggle that propagates down to the node items and indicates one of the following states:

    None of the datasets are selected: Deselecting a parent node deselects all child datasets.

    All the datasets are selected: Selecting a parent node selects all child datasets.

    Some but not all of the datasets are selected: Selecting at least one child dataset results in a "partial selection" for the parent node.

If a filter is applied, selected items in the tree list are tracked, and the number of filtered-out objects appears in parentheses. The total count of selected objects includes both visible and filtered-out items. Clearing the filter removes the text and the count in parentheses, and updates the total count accordingly.

The selection state of datasets is retained after publishing and reopening the dialog within the same project. However, this state remains fixed when switching workspaces.

  • Datasets published to other workspaces will be disabled and, therefore, unselected in the current workspace.

  • Disabled datasets in other workspaces that are enabled in the current workspace will also not be automatically selected.

If the dialog is launched from the context menu in the Project Explorer, only the datasets selected at that time will be checked in the list.

Clearing parameters (Project > Parameters > Clear Parameters) resets settings in both the 'Publish to Seequent Evo' and 'Import from Seequent Evo' dialogs and removes previous dataset and workspace selections.

Script Parameter: PUBLISH_TO_EVO.SELECTED_OBJECT_PATH_0

[Select All]

Click this button to select all datasets. The total number of datasets will be displayed.

If a filter is applied after items have been selected, Select All applies only to filtered items, leaving previously unselected items outside the filter unchanged.

  • Clicking Select All does not alter the selection status of items outside the filter.

  • Only the original dataset count (outside parentheses) updates as items are selected individually or via Select All.

[Select None]

Click this button to deselect all datasets.

If a filter is applied after items have been selected, Select None applies only to filtered items, leaving previously selected items outside the filter unchanged.

  • Clicking Select None does not change the selection status of items outside the filter.

  • Only the original dataset count (outside parentheses) updates as items are deselected individually or via Select None.

Open Seequent Evo after publishing

Select this option to launch the Seequent Evo portal once publishing is complete.

If you're not signed in, the evo.seequent.com/login page will open. Click the [LOGIN] button in the top-right corner and sign in with your Bentley account.

By default, the workspace where you published the data will open, and the Geoscience Objects tab will display the uploaded data.

Script Parameter: PUBLISH_TO_EVO.OPEN_PORTAL [0: unchecked; 1: checked]

[Publish]

Click the Publish button to close this dialog and initiate the publishing of the selected dataset(s) as geoscience object(s) to Seequent Evo in the selected workspace.

If a filter is active and some selected items are hidden due to filtering, a confirmation prompt will appear, asking you to confirm whether you want to publish all selected items, including those filtered out. To exclude them, clear the filter.

The publishing process runs in the background, allowing you to continue working while large datasets are uploaded to Seequent Evo. Multiple instances can run concurrently for different datasets.

Monitoring Progress in Project Explorer:

  • You can track publishing progress while working on other tasks. The status (e.g., processing, completed, failed, cancelled) and the number of jobs being processed are visually indicated in the Jobs tab.
  • New entries for translated and published objects appear in the Jobs tab, under a new node in the tree, marked with the Seequent Evo icon.
  • Failures or warnings are signaled with a notification icon on the job's node. Click the icon to view the captured error or warning. For individual entries/tasks, additional details may be available, indicated by an exclamation icon . Click the flagged entry's icon for more information.

    • Refer to the Jobs section in this topic for more details on monitoring progress and reporting results.

  • In the Data tab: The published dataset's icon will display a modified version featuring the Seequent Evo symbol, indicating that it has been successfully published to Seequent Evo:

The icons of published datasets, displaying the Evo symbol, will be visible in window headers when the datasets are opened in the current project. However, they will not appear in the Map Manager and 3D Manager panes.

Evo References Across Projects

Evo references are not transferred or shared between projects. Published objects added to another project will be "unlinked" from Evo, and these datasets will not display the Seequent Evo icons. However, if the entire project directory is shared, Evo references are also shared, and the published Evo objects will preserve their Evo links.

Removing Published Objects

When you remove published objects from the current project using the Remove from Project or Remove All... context menu options, their Evo references are lost. Re-adding them to the project will not restore their link to Seequent Evo, as indicated by the absence of the Evo symbol on their icons.

Closing the Project During Publishing

If you close the project or exit Oasis montaj while a background process is running, a confirmation prompt will appear. Proceeding with this action may result in only a partially published dataset or datasets.

Application Notes

*The GX.NET tools are embedded in the geogxnet.dll file located in the "...\Geosoft\Desktop Applications \bin" folder. If running this GX interactively, bypassing the menu, first change the folder to point to the "bin" directory, then supply the GX.NET tool in the specified format. See the topic Run GX for more details on running a GX.NET interactively.

Supported Data Types

When publishing to Seequent Evo, your data will be saved in a Geoscience Object format that can be shared between Oasis montaj and other Seequent desktop and cloud applications. The following dataset types can currently be published as geoscience objects:

Grids
Voxels

  • Numeric and thematic voxels are published to Seequent Evo as Regular 3D Grid types.

  • Numeric voxels with varying cell sizes are published to Seequent Evo as Tensor 3D Grid types.

  • Unsupported types:

    • The vector voxel type is not supported. It is not available from selection in the 'Publish to Seequent Evo' dialog, and the 'Publish to Seequent Evo' context menu is not available for this type in the Project Explorer.

Spatial Reference

The geoscience object retains the coordinate system (CS) and CS units of the published dataset. Additionally, the following attributes are preserved: spatial extents (X, Y, Z), origin, and orientation.

A Seequent Evo workspace can contain objects with different coordinate systems; however, it is preferable for all objects within a workspace to use the same coordinate system.

Colour Display

The datasets are published to Seequent Evo with their most recent colour display properties (colour scheme and distribution) as they were last shown in their respective viewers (e.g., Grid Viewer or Voxel Viewer).

Colour Shading

When publishing a colour-shaded grid, only the original grid file is included. The "_s.grd" auxiliary grid file, generated in the project folder, is not published.

Colourmaps

When publishing a grid or voxel dataset to Seequent Evo, the Colourmap API:

Example of sharing and visualising geophysical data:

In Oasis montaj, a grid dataset is published to Seequent Evo.

  • The dataset is uploaded as a geoscience object along with its associated colourmap, which stores colour display properties (e.g., colour scheme, distribution).

  • A geologist imports the geoscience object from Seequent Evo into their Leaprog instance, ensuring:

    • Colour display settings remain consistent across platforms

    • No manual adjustments are needed

  • The data in Leaprog is visualized exactly as it appears in Oasis montaj, using the imported colourmap—eliminating the need to manually recreate colour settings.

Similarly, a geological model can be published from Leapfrog to Seequent Evo.

  • A colleague then imports the published geoscience object into an Oasis montaj project.

  • The imported geosurface, which includes surfaces corresponding to the geological features or layers within the geological model, is displayed with the same colour fidelity as in Leapfrog.

  • This seamless integration ensures accurate colour representation without loss of detail, enabling a geophysicist to leverage the model for tasks such as building a VOXI inversion.

Supported Colourmap Types

When publishing to or importing from Seequent Evo, the following colourmap types are supported:

  • Discrete: For grid or numeric voxel datasets, a discrete colourmap is generated, mapping ranges and colours to dataset values. Each colour corresponds to a specific value range or numeric interval.

  • Category: For thematic voxel datasets, a category colourmap is created and linked to the published geoscience object, mirroring its lithology classification codes and colours.
    Thematic (lithology) voxels use rock code colours stored in a predefined lithology/rock code CSV file, which includes:
    • A “Code” field that matches the lithology classification of the geological data used in generating the voxel.
    • A “Colour” field defining numerical values assigned to each code.

When importing into Oasis montaj, the following colourmap type is also supported:

  • Continuous: Uses colour gradients stretched across a range of values. When importing a geoscience object with a continuous colourmap (where the colour of a cell is a function of the gradient controls), the colourmap is discretized using linear distribution and mapped to Oasis montaj's internal colourmap representation.

Log and Cache Files

Each publishing session generates an entry in the Evo log file, which records timestamped processing details. This log file is stored in the log folder within the evo directory, located in the temporary file directory.

Additionally, for each publishing session, a cache sub-folder is created in the publish folder within the evo directory. This sub-folder is assigned a unique eight-character identifier.

Resolving Publishing Failures Due to Cache File Name Length

If a dataset fails to publish because its fully qualified cache file name exceeds the 260-character limit, consider one of the following solutions: 

  • Rename the file: In the Project Explorer tree, right-click the dataset and select Rename to shorten the file name.

  • Change the temporary file directory path: Go to Project > Settings > General and adjust the Temporary file directory path to shorten it.
