Grid Case Group’s are designed to make it easy to calculate statistics per cell and per time step of a large number of Eclipse simulation Cases with identical Grids (often labeled realizations).
If you have several Eclipse simulations with different input parameters available, you can put all the realizations into a Grid Case Group and easily calculate each of the cells mean value, range and max/min values at each time step. Grid calculations can optionally be used as a data source for computations.
The easiest way to create a Grid Case Group is to use the Import command: File->Import->Eclipse Cases->Create Grid Case Group
This command will display the recursive file import dialog described on the Summary Plots page.
ResInsight then creates a Grid Case Group for you, and populates its Source Cases with the Cases you selected. Then the first of those Cases are read completely, while the others are just scanned to verify that the Grids match and to detect changes in the Active Cells layout. This makes it quite fast to load even a quite large number of realizations.
A Grid Case Group can be created from the right-click menu of a Result Case, Input Case or a different Grid Case Group. Source Cases can then be added by using the mouse to drag and drop cases with equal grids into the Grid Case Group’s Source Case folder. This is useful if you want to create statistics based only on a subset of the source cases in an already created Grid Case Group.
Drag and Drop of cases will normally copy the cases to the new destination, but moving them is possible by pressing and holding the Shift key while dropping.
To reduce the number of views, only a view for the first case is created automatically. If you want to inspect the results of a particular source case, select New view from the right-click menu. A new 3D View will the be created on that particular case.
After creating a grid case group, an empty Statistics Case is created for you in the Derived Statistics folder of the Grid Case Group.
Settings for grid case property statistics
Settings for grid cell calculations
Cell values in a selection of cells can be aggregated as described in Aggregation of Grid Cell Values
Settings for when statistics has been computed
Three Percentile methods are implemented:
When the computation is complete, you have to create a 3D View on the Statistics Case to view the results. Use the right-click menu of the Statistics Case to create it.
A new statistical calculation can be created by activating the right-click menu for Derived Statistic->New Statistics Case.
