ResInsight supports the following type of Eclipse input data:

• *.GRID and *.EGRID files along with their *.INIT and restart files *.XNNN and *.UNRST.
• Grid and Property data from *.GRDECL files.

Importing Eclipse cases

Eclipse Results

1. Select File->Import->Import Eclipse Case and select an *.EGRID or *.GRID Eclipse file for import.
2. The case is imported, and a view of the case is created

TIP: You can select several grid files in one go by multiple selection of files( Ctrl + left mouse button, Shift + left mouse button).

Eclipse ASCII input data

1. Select File->Import->Import Input Eclipse Case and select a *.GRDECL file.
2. The case is imported, and a view of the case is created
3. Right click the Input Properties in the generated Input Case and use the context menu to import additional Eclipse Property data files.

Handling missing or wrong MAPAXES

The X and Y grid data can be negated in order to make the Grid model appear correctly in ResInsight. This functionality is accessible in the Property Editor for all Case types as the toggle buttons Flip X Axis and Flip Y Axis as shown in the example below.


Export of Eclipse Properties as ASCII data

Eclipse Properties can be exported to Eclipse ASCII files by activating the context menu for a Cell Result. 

The command will export the property set currently loaded and shown in the 3D View to a file with the following format:
