Hall plot

The slope of a Hall plot indicates a well's average injectivity. At normal conditions, this plot is a straight line; deviations indicate changes in injection conditions. For more information, see Hall plot theory.

Note:    The Hall plot uses tubing pressure, not injection tubing pressure, as an input.

You can display this plot as follows:

  • Click Injection, Water, and drag Cumulative Water Inj to the x-axis.
  • Click Hall, and drag Hall Coefficient or Hall Coefficient Slope to the y-axis.
