Aggregation of Grid Cell 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 for the region of interest.
  • Create an expression for mobile oil MOBILE_OIL := if(((SOIL-SOWCR) < 0.00), 0.00, PORV*(SOIL-SOWCR))
  • Select a subset of time steps. This will significantly affect performance for for large grids with many time steps.
  • Create an expression to aggregate 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.
  • Make sure Apply to All Cases is checked.
  • 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.
