Sum Production Streams

 

This function sums multiple production streams into a single production stream.

To open the Sum Production Streams tool, select Compute>From Production>Sum Production Streams... from the menu bar at the top of the Main Module.

Data tab

Sum Production in New Stream -This dropdown selects the production stream that will contain the sum.  Select an existing production stream or enter a new name.  Note that selecting an existing production stream will overwrite the production stream in the database.

Select Streams to be Summed - This list selects the production streams to sum together.  Use SHIFT to select multiple successive streams, or CTRL to select streams individually.

Options tab

Scale Factor for Computed Stream - This option multiplies or divides the production stream by a constant.  This can be useful for changing the  production stream's order of magnitude.  The default "(none)" option does not change the data.

Cumulative Production Value - This option stores a cumulative production value to a selected zone data item.

Generate an Associated "Count" Stream - This opten creates a count stream that stores the number of streams contributing to the summed production.  Petra will store a stream that appends "_CNT" to the name of the new stream.  In the example above, the count stream will be named "OIL_WC-NB_CNT"

 

Load/Save Settings - These buttons save and load the settings on the Sum Production Streams tool to an external *.SPS file.  This can be useful for running the same calculation multiple times.
