-## Aggregation of of Grid Cell Values and Statistics
-- import a grid case ensemble
-- define a summation in the grid calculator, mySum := sum(cellProperty)
-- in the Statistics case, select the grid calculation expression
-- create a view on the Statistics case
-- select a set of cells
-- in the Statistics case, select the view as a filter
-- click compute
-- the result of the summation is displayed as text in Messages window. The statistics based on values in each time step is displayed below the individual realization values.
+### Calculate statistics for sum of mobile oil for an ensemble
 
+**Workflow description**
 
+- Import an ensemble of grid models with identical IJK into a **Grid Case Group**.
+- Create a view on one of the source grid models, and create a cell filter.
+- Create an expression for mobile oil `MOBILE_OIL := if(((SOIL-SOWCR) < 0.00), 0.00, PORV*(SOIL-SOWCR))`
+- Optionally select a subset of time steps
+- Create an expression to sum values for all visible cells `SUM_MOBILE_OIL := sum(MOBILE_OIL)` Use the result from the previous calculation as input to the variable, use `MOBILE_OIL` from the **Generated** category.
+- The individual values for each realization and time step is displayed as text in **Messages**. The statistics for each time step is displayed at the bottom.

 ResInsight offers a built-in property calculator for grid parameters. 
 The **Grid Property Calculator** enables arithmetic expressions to be parsed and calculated for visualization purposes. The expression can be applied to one or multiple grid models, and the expression text can be stored to a file for later use.
