About the GIS Data Link Plug-in for Petrel
With the Geocap GIS Data Link for Petrel plugin makes it easy to export data you can seamlessly transfer subsurface data, including ZGY seismic, from Petrel to ArcGIS features in a geodatabase.
Supported data types
The ArcGIS database exporter plugin allows you to export well headers, trajectories, well logs, well tops, 2D seismic lines, seismic cubes, surfaces, 2d horizon interpretations, 3d horizon interpretation grids, point sets and polylines to an ArcGIS geodatabase.

Downloading the plugin
Please contact info@geocap.no for details on how to acquire the software.
Installing the plugin
Extract the downloaded .zip archive to a folder on your computer.
In Petrel go to File→Options → Plug-in manager, press Install plug-in ... and browse in the Geocap.Petrel.ArcGis-XY.pip inside the extracted folder (where XY is the version number and Petrel version).
Using the plugin
Please enable the Processes pane from the Panes button under the Home toolbar.
The plug-in installs a new Petrel process Export data to ArcGIS geodatabase in the Processes → Plug-ins group folder.
NB! Before actually exporting any data you need to go to the Settings tab in the plug-in GUI and press the Install button in the License section. You then browse in a license file which you should have received together with the .pip file.
If at least one well is selected this process creates 5 feature classes (tables):
- Wellheads
- Boreholes
- WellLogs
- DictionaryColorTables
- WellTops
The Wellheads table contains 1 geographical point for each wellhead. Each feature in the feature class corresponds to one well head.
Each wellhead may have one or more boreholes (trajectories). Each borehole is a line in the Boreholes table.
Each borehole may have one or more logs. Each log is a line in the WellLogs table.
One or more of these logs may be discrete. Each discrete log, eg. Facies, has a row in the DictionaryColorTables table for each value with CodeName (eg. Sand)
Each borehole may also have one or more welltops. There is one feature for each welltop in the WellTops table.
If at least one 2d seismic line has been selected a feature class named SeismicLines is created with one line feature per seismic 2d line.
The seismic amplitudes are exported as as TIFF rasters to the user specified Seismic data folder. The export of the amplitudes may be turned off by checking Export only navigation under Settings→2D seismic line.
If at least one 3d seismic cube has been selected a feature class named SeismicCubes is created with one feature per seismic cube in ZGY format.
Each feature has a polygon showing the outline of the seismic cube. If the option Create livetrace polygon outline is checked under Settings→3D seismic cube this polygon shows where the cube actually has data, excluding traces that are zero.
If at least one 2d horizon interpretation has been selected a feature class named HorizonInterpretation2Ds is created with one line feature per interpretation.
If at least one 3d horizon interpretation grid has been selected a feature class named HorizonInterpretation3Ds is created with one multipoint feature per interpretation.
Selected Surfaces are exported as TIFF rasters to the user specified Raster data folder.
If at least one Point set has been selected a feature class named Points is created with one multipoint feature per point set.
If at least one Polyline set has been selected a feature class named Polylines is created with one polyline feature per polyline set.
The table names mentioned above may be modified using the Feature class prefix.
You may either let the Export data to ArcGIS geodatabase process create a new file geodatabase or append to an existing one.
Viewing in ArcGIS Pro
All feature classes can be viewed in 3D ArcGIS as is without any further manipulation except for the well logs which require correlation with the trajectories and will therefore not appear in a meaningful way in the 3D display.
Publishing for ArcGIS Server
The output from the Geocap Petrel plugin can be viewed in 3D in a web browser by publishing the features classes as a map service and then using the seismic server web app to visualize. Note that Seismic Server SOE is not required.
To have the output from the Geocap Petrel plugin available in web 3D:
...
without using any intermediate formats and easily make your data available for publishing to the Geocap Subsurface Portal. The plugin offers a user-friendly menu which allows the user to export a specific dataset or do a bulk export of multiple datasets.
Features:
• Export surfaces directly to rasters
• Export points, lines and polygons directly to feature classes
• Polygons are automatically closed (no need to generate geopolygon first)
• Generate live trace outlines of seismic cubes
• Export wellheads, well paths, tops and logs
• Export a georeferenced screenshot from your 2D window (geotiff)
• Import geotiffs to Petrel
