Exporting to CMG

After an advanced numerical model has been created, you can export it to CMG IMEX – the industry-accepted black-oil simulator by Computer Modelling Group (CMG) Ltd.

Note:

This feature is available for the black oil and modified black oil models, but it is not available for coalbed methane (CBM) numerical models.

To export to CMG:

1. Click the Export to CMG () icon on the numerical model's toolbar.

The Save As dialog box opens.

2. Save your .dat file with the default filename, or rename it if you want.

After this is done, you can run the .dat file in CMG IMEX. If you wish to modify the .dat file, you can load it into the CMG Builder and edit it there. Or, you can use any text editor.

The .dat file contains the following information:

• Model dimensions and gridding
• Rock properties
• Fluid properties
• Completion information (e.g., well location, number, and size of fractures)
• Well control information (e.g., if the Use Oil Rate calculation method is selected for the model, oil rates are written to the appropriate section of the .dat file)

Note:

The current implementation of the Export to CMG feature does not support some of the advanced model parameters. If you try to export a model that has such parameters, an error message is displayed in the Status Window, and the CMG .dat file is not created. To open the Status Window, click the View menu and select Toolbars and Docking Windows, Status Window.
