Synonym: Watercut Diagnostics = WOR Diagnostics
Part of Production Analysis related to analyzing the production watercut dynamics and the possible reasons of its specific behaviour:
regular displacement, bottom-water encroachment, coning, thief water production via channeling or tubing/casing failure.
