How to use the plugin

 

The Plug-in Interface

To open the plug-in:

  1. Go to the Home toolbar in Petrel, press the Panes button and select Processes.

  2. In the Processes pane go to the Plug-ins group folder and double click Export data to ArcGIS geodatabase. A dialog box will appear.

The dialog box has three tabs. The Export to ArcGIS geodatabase tab is used for selecting data for export and setting up the export destination. Data from the Petrel Project input pane available for export is displayed in the box to the left. If you wish to only export the 2D seismic navigation (and not the amplitudes as rasters) it is possible to tick off this option in the Settings tab. Options for creating livetrace polygons for 3D seismic cubes and closing polygons automatically can also be found under this tab. Helpful hints regarding the data export are located under the Hints tab.

The following datasets are supported by the plugin:

  • Wells

    • Well heads

    • Trajectories

    • Well logs

    • Well tops

  • 2D Seismic lines

    • Navigation

    • Amplitudes

  • 3D Seismic cubes

    • Outline

    • Amplitudes

  • 2D Horizon interpretation

  • 3D Horizon interpretation

  • Surfaces

  • Point sets

  • Polyline sets

  • Geopolygon sets

Selecting data to export

Wells

If at least one well is selected it will create 5 feature classes (tables):

  1. Wellheads - The Wellheads feature class contains one geographical point for each wellhead. Each feature in the feature class corresponds to one well head.

  2. Boreholes - Each wellhead may have one or more boreholes (trajectories). Each borehole is a line in the Boreholes feature class.

  3. WellLogs - Each borehole may have one or more logs. Each log is a line in the WellLogs table.

  4. DictionaryColorTables - 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)

  5. WellTops - Each borehole may also have one or more welltops. There is one feature for each welltop in the WellTops table.

2D seismic

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.   

3D seismic

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.

2D & 3D Horizon Interpretation

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 has been selected a feature class named HorizonInterpretation3Ds is created with one multipoint feature per interpretation.

In general, if the horizon interpretation is large, e.g an autotracked 3D interpretation, it is recommended to generate a surface from the interpretation points and export as a surface instead of a horizon interpretation.

Surfaces

Selected Surfaces are exported as TIFF rasters to the user specified Raster data folder.

Points & Polylines

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.

Geopolygon sets

 

 

You may either let the Export data to ArcGIS geodatabase process create a new geodatabase file and enter its target location and name or append to an existing one by pointing to this (Figure 3). The feature class names mentioned above may be modified by entering a Feature class prefix.

Surfaces and 2D seismic lines are stored outside the file geodatabase as tiff rasters. If you choose to export one or more surfaces, a target folder must be specified. Similarly, a folder for 2D seismic rasters must be specified if 2D seismic rasters are exported (not navigation, -see above).

ArcGIS uses a slightly different CRS naming system than Petrel. The WKID will in most cases be automatically filled in by the ArcGIS WKID corresponding to the Petrel Project CRS. The data is assumed to be in this CRS. No conversion will take place, even if a different WKID than the automatically selected is entered.

Click OK to export the data.

Exporting a Georeferenced Screenshot

When the plug-in is installed a GeoTiff button will also be available to the far right in the Home tab toolbar in Petrel. This button lets the user generate and save a georeferenced .tiff image of the active 2D window in Petrel. This can then e.g. be imported into ArcGIS Pro to check that your data is positioned correctly.

Import GeoTiff

An additional feature of the plug-in is the possibility to import grids in the Geo Tiff format. This file format is available in the list of file types in the standard data import dialog when importing data into a folder in the Petrel input pane.
