Data Discovery - Files Table - ITAG AI search

An Information Tag (ITAG) AI-based search feature has been added to the Files Table. This returns files with matching ITAGs across all projects to the Files Table in the Data Discovery page. The Map, Project Table and Files Table are linked, so the filtering in the Map or Projects table will update the Files Table, thus enabling the user to apply filtering to find specific groups of files in the search results.

The Information Tag Search Box is at the top centre of the Files Table. Users can type in a question or ITAG to help them find types of data. The Search system uses a large language model (LLM) to select the most appropriate ITAGs for whatever the question is. All files of the various ITAGs are then returned to the Files Table, and the user can then filter the data based on spatial selection in the Map, or by filtering columns in the Project and Files Tables. 

This search feature is not visible or available to Public Users and is currently marked as a Preview feature. The search uses an AI Agent and a large language model to provide answers; it may therefore return incorrect ITAGs.

Users start searching by typing a query in natural language into the Information Tag Search Box. The search button will not become live until the user has entered a query into the Information Tag Search Box. The query can also just be the name of an ITAG or CTAG, or just a grouping like “all seismic files”.



Once the Query has been entered, press the search button, and Files will start to load to the Files Table.

Please note that loading “all files” into the table will load > 1.3 million rows into the file table for further filtering and discovery. A user's local IT environment and hardware may impact performance where large proportions of the data collection are being accessed.

The other buttons in the Search interface will appear once the results have been returned

• “Search” performs the search based on the entered user query
• “ITAGs found” displays ITAGs that match the search query
• “Show on Map” displays results on the map
• “Clear” clears the search query from the text input

The “ITAGs found” button displays the Information Tags matched by the search query and a Confidence Score. The table is sorted by decreasing confidence score. A higher confidence score indicates that the LLM thinks the ITAG is a better match to the answer to the User query. Only ITAGs returned with a confidence score greater than 0.7 are loaded into the Files Table. The following screenshots show some examples of queries and their returned ITAGs. 

Depending on the query, many files can be loaded to the Files Table, for example, for one query string, the search resulted in 470,451 rows being added to the Files Table.

After the search has completed, clicking “Show on Map” displays the location of the files from the query on the map, and the button name updates to “Hide on Map”, which would remove them from the map display. 

Displaying files on the map plots a data density layer when the number of results exceeds 50,000. The data density layer shows the number of files per spatial hexagon, the colour coding of the hexagons corresponds to quartiles in the file density distribution, and the number can be read on the map legend. 

Other map sources can be displayed alongside the file search results. The image below shows a zoomed-in file density plot with the Carbon Storage Licence GIS Layer overlain.

Any outline or free-drawn polygon can be selected on the map. For example, selecting a Carbon Storage Licence will filter the Project IDs and Files Tables based on the outline of the polygon. The map will only update when the “Update Map” button is pressed.

The map will only update the search results layer when the “Update Map” button is shown and the user clicks it.

Now that the map item is selected, the “Update Map” button can be pressed to show the filtered files on the map. The filtering reduced the number of results in the Files Table to less than 50,000 results, so the file geometries are shown on the map instead of a file density plot.

Selecting a file on the map updates the map to show the selected file. For this SEG-Y file the pop-up has buttons to preview the SEG-Y data or SEG-Y header.

Clicking on the “SEG-Y data” button on the pop-up will open the seismic preview window and load a subset of the data to preview the SEG-Y data.

Further filtering can be applied in both the Project and Files Tables from any of the column filters; for example, filtering down by file type of “LAS” and MTAG of “sonic”, will reduce the number of files shown in the Files Table. Subsequent clicking of the “Update Map” button will show the files as points on the map. These files can be selected on the map by clicking on them, which will open the file information pop-up on the map, simultaneously the files table will update and scroll to show the file as the first row in the Files table.

A spatial query can be drawn as a freehand polygon on the map using the polygon map tool. The Project ID and Files Tables will then be filtered based on the user polygon. In this example, the number of rows has reduced to 983.

Clicking “Update Map” will show the geometries on the Map of the files currently shown in the Files Table.

Data Submission - LAS file track name mnemonics dictionary for MTAGs

LAS files are now scanned on upload to extract the track name mnemonics, these are then translated through a dictionary into a reduced set of Metadata Tags (MTAGs). The MTAGs are then available in the Files Table where they can be used to locate or select particular LAS files.

Examples of the conversion of Track Name Mnemonics to MTAGs are:

The preview window in the upload page for a LAS file now shows the extra metadata extracted from the LAS file when clicking on the file name in the upload table.

Data Submission - Manage Completeness

There are now three Buttons for generating completeness reports:

These Buttons are:

1. “Download Completeness Reports (grouped by Well ID or Survey ID) with extra well data from GIS (slower to run)”
   • This is the existing completeness matrix report, which collects all projects of the same Survey ID or Well ID together into a single entry, and the output is a single row per Well ID or Survey ID. 
   • This report has additional information about any wells extracted from the NSTA GIS system (GIS attributes COMPLESTAT, SPUDDATE, DATETDREAC and  COMPLEDATE). This additional data extraction during the report creation means that running this report can take several minutes
2. “Download Completeness Reports (grouped by Well ID or Survey ID) no GIS (quicker to run)”  
   • This is the output as the existing completeness matrix report, which collects all projects of the same Survey ID or Well ID together into a single entry, and the output is a single row per Well ID or Survey ID. 
   • This report is much faster than the first report for wells, as it does not go and query the NSTA GIS for each well to get additional well information. The output rows and columns are the same as the first report, but this one has blank entries in the additional GIS well information columns.  
3. “Download Completeness Reports (grouped by Project ID)” 
   • This outputs a completeness matrix report where the output primary key for each row is Project ID. Any Well or Survey that is part of more than one project will have an output row for each project.
   • This report is the fastest as it is just reporting per NDR project 

Data Discovery - Files Table - Export Rows to CSV 

The export rows to a CSV file button now changes its behaviour depending on the display state of the Files Table. 

Once files are loaded to it and there is no filtering or selection applied to the rows then the button will be named “Export All Rows” and clicking it will export all the rows to a CSV file to the default download location on the user's computer. 

After the Files table has some filtering applied to it to reduce the number of rows visible in it, then the button will update to be named “Export Filtered” and clicking will export the displayed rows to a CSV file to the default download location on the user's computer.

If rows are selected in the Files table, then the button will update to be named “Export Selected” and clicking will export only the selected rows to a CSV file to the default download location on the user's computer.

Once single or multiple rows have been selected the “Clear Selected” button will become active and clicking this will unselect all the selected rows in the Files Table.

Data Discovery - Project Table - Export Rows to CSV 

The export rows to a CSV file button now changes its behaviour depending on the display state of the Project Table. 

Once projects are loaded to the Projects Table and there is no filtering or selection applied to the rows then the button will be named “Export All Rows”, clicking it will export all the rows to a CSV file to the default download location on the user's computer.

After the Project table has some filtering applied to it to reduce the number of rows visible in it, then the button will update to be named “Export Filtered” and clicking will export the displayed rows to a CSV file to the default download location on the user's computer.

If rows are selected in the Project table, then the button will update to be named “Export Selected”, and clicking will export only the selected rows to a CSV file to the default download location on the user's computer.

Once single or multiple rows have been selected, the “Clear Selected” button will become active and clicking this will unselect all the selected rows in the Projects Table.

Once a single or multiple rows have been selected the “Show Selected” button will become active, and clicking this will filter the Projects Table to show only the selected rows.

Data Discovery - Overview Map - Export Files to GeoJSON

Map Layers that originate in the NDR can be downloaded to the user’s local computer as GeoJSON files, this done by clicking on the down arrow to the right of the Layer name on the Map Layers Menu. Holding the user's mouse over the button will show its function.

Data Discovery - Overview Map - NSTA Offshore Licences Layers

New layers added from the NSTA GIS showing all offshore licences for:

1. Petroleum Licences
2. Carbon Storage Licences
3. Carbon storage application areas
4. Gas Storage Licences
    

These polygons can be clicked on to filter the Projects and Files Tables to only show Projects that intersect with the polygon
