ph on a PurgeInterval is one of the key parameters tracked to assess purge stabilization. The trend of ph across sequential PurgeIntervals shows whether the formation water is coming through consistently. A stable ph (varying less than 0.1 units between intervals) is one of the standard criteria for declaring stabilization on the parent PurgeLog. Reviewers compare PurgeInterval ph values over time to verify stabilization was genuine.
