Importing simulation results
You can import the results from a prior simulation run using the Import Results form in the Tools button group of the simulate strip (Simulate > IMEX or GEM or STARS > Tools > Import Results).
-
Select or create destination case There are two options available:
Select a simulation case If you want to import the results for an existing simulation case, select a case from the drop-down list.
Import result data only Select this option if you want to import result as a new simulation case. You can name the case in the 'Destination simulation case' field on the form below. After importing the results data, a 3D grid is created and the grid properties as well as the results are stored under the Properties folder in the newly created grid.
-
Select the simulation result file
Results file (.sr3) Click the ellipsis button
to open the case folder and select the result file in .sr3 format. -
Import the selected file
Destination simulation case Name of the destination case folder.
- If you have selected 'Select a simulation case' in the step 1, this field is grayed out and uneditable. The results are imported to the previously selected existing simulation case.
- If you have selected 'Import results data only' in the step 1, you can give a name to the case in the adjacent field. After importing the results, a new simulation case in the Case Explorer and a new 3D grid in the JewelExplorer with this name are created. The newly created 3D grid will contain the grid properties as well as the 3D grid simulation result properties, under the Properties folder.
Import 3D grid data Check this option if you want to import the 3D grid properties for the case.
Import production data Check this option if you want to import the well production data for the case.
Click the Import file button to complete the importing of the results.
The ‘Link to Wellbores’ form automatically pops up in case not all simulation wells could be linked to a JewelSuite wellbore. You can always access the form later to QC or update the wellbore linking. For more information, see Link to Wellbores. - If you are missing a simulation results file for an existing case, a warning message will appear in the Output Information pane. Use the Locate result files button on the form to manually locate the missing results file via the Missing Simulation Result Files view.
When visualizing simulation results from reservoir simulators (CMG, Eclipse and tNavigator) JewelSuite optimizes the loading of results and uses a feature called lazy loading in specific scenarios. In other words, the data is loaded on demand only when needed, rather than upfront all at once. This approach significantly improves performance when visualizing simulation results for large models with high number of time steps or time series. To fully understand when lazy loading applies, please read the entire topic carefully, as the specific scenarios are explained in detail below.
Loading behavior for 3D grid simulation result properties
When 3D grid simulation result properties are imported to a simulation case (either automatically at the end of a run or manually into an existing case), the loading behavior for all reservoir simulator types (CMG, Eclipse and tNavigator) is the same:
- JewelSuite does not store the data in the *.jewel file.
- When you visualize these properties in a 3D View, JewelSuite loads them on demand from the simulation result file.
- The simulation result file is located in the simulation case subfolder, under the *.Cases folder.
Loading behavior for simulated production data
When simulated production data is imported to a simulation case (either automatically at the end of a run or manually into an existing case), the loading behavior depends on the simulator type:
- For CMG (SR3 files) Simulated production data is not stored in the *.jewel file. When you visualize these results in a production chart, JewelSuite loads them on demand from the SR3 file, which is located in the simulation case subfolder, under the *.Cases folder.
- For Eclipse and tNavigator Simulated production data is stored in the *.jewel file. When you visualize these results in a production chart, the original simulation result files are not needed.
Exceptions for 'Import result data only' option
When you manually import simulation results using the 'Import result data only' option on the Import Results form (Simulate > your simulator of choice > Tools > Import Results), the loading behavior depends on the simulator type:
- For CMG (SR3 files) Simulation results (both 3D grid properties and production data) are not stored in the *.jewel file. The imported SR3 file is copied to the simulation case folder. JewelSuite loads the data on demand from the SR3 file copied to the simulation case folder and no longer uses the original SR3 file used for import.
- For Eclipse and tNavigator The loading behavior is different for simulated production data and 3D grid simulation result properties:
- 3D grid simulation result properties data is not stored in the *.jewel file. When you visualize these properties in a 3D View, JewelSuite loads them on demand from the simulation result file, which is the original simulation result file used for import.
- Simulated production data is stored in the *.jewel file. When you visualize these results in a production chart, the original simulation result files are not needed.
If simulation result file is missing
If you have any open views in your solution that rely on loading data on demand and the simulation result file is missing, an error message is displayed. The message guides you to manually locate the missing files using the 'Missing Simulation Result Files’ form (Simulate > your simulator of choice > Tools > Import Results > Tools > Click ‘Locate result files’ button).
SR3 is the standard file format for simulation results used by the CMG simulators, and JewelSuite Subsurface Modeling supports this format. This format was introduced with CMG's 2016 product release. In case your simulation results are not available in the SR3 format, you can use the pre-installed executable from CMG to convert the SR2 files (*.irf and *.mrf) to SR3 format.
The conversion tool is available in the Program Files folder as 'imrf2sr3.exe'. Follow the steps below to convert the SR2 (*.irf and *.mrf) results file in SR3 format.
- Locate the executable for the convertor in your computer. Most users will have the executable location similar to this: C:\Program Files\CMG\RESULTS\2025.30\Win_x64\exe\imrf2sr3.exe
- Locate the folder containing the .irf and .mrf files that you want to convert.
- By default, the converted results file will be saved in the same folder. Optionally, you can also save the output file (.sr3) to a different folder location.
- In the Command Prompt, type the following command and press enter: <"executable location"> -r <"results file .irf"> -o <"output results file .sr3">. Note that the script from '-o' onwards is optional and refers to the output folder location. The converted files are saved in the same results folder if this part is skipped.
An example of the script: "C:\Program Files\CMG\RESULTS\2025.30\Win_x64\exe\imrf2sr3.exe" -r "D:\Project_dynamic_simulations\IMEXCase\IMEXCase.irf" -o "D:\Project_dynamic_simulations\Result_case_files\IMEXCase.sr3".
