Eclipse grid data
File type: Various data file
The .egrid file extension identifies grid data used by Eclipse reservoir simulation software.
An .egrid file contains the grid description for a reservoir simulation case and is normally handled as part of an Eclipse project.

The .egrid file extension is associated with Eclipse, a reservoir simulation application from Schlumberger, now SLB. It is not related to the Eclipse integrated development environment.
An .egrid file stores binary grid data used to describe the model grid for a reservoir simulation. The file is used together with other Eclipse case and output files rather than as a standalone document.
Eclipse and its related tools are available for Microsoft Windows, Apple macOS and Linux/Unix. The EGRID format remains associated with Eclipse simulation workflows and specialized reservoir-model visualization software.
Open the .egrid file with Eclipse on Microsoft Windows, Apple macOS or Linux/Unix. It is usually opened from the corresponding simulation case or loaded by a compatible reservoir-model visualization tool.
An .egrid file is a binary data file, so it is not intended to be read in a text editor.
An .egrid file is not normally converted with a general-purpose file converter. Use Eclipse or compatible reservoir simulation and visualization software to export the grid to a format supported by the target application, when that option is available.
