Primary Source: Stage or Borehole

You may have both borehole-level data and stage-level data, probably from different sources. The two different views based on the selected Primary Source, Borehole and Stage, allow you to easily switch between both sets of data. The primary source changes what you see in the Summary views . The differences in the data are noted below:

Borehole	With borehole as the primary source, the stimulated length is taken from the borehole-level Treatment Summary tab: End Depth minus Start Depth.
Stage	With stage as the primary source, the stimulated length is taken from the stage-level Stimulation tab, and is the sum of all stage lengths.

To change the primary source, click your preference at the top of the Completions summary, and at the top of relevant tabs.
