Methods for determining and validating a first phase fraction of a gravitationally-separated multiphase fluid by conducting physical and electrical property measurements on samples of the fluid. The water content of crude petroleum oil is determined after the oil and water have begun to separate into phase layers such as occurs during un-agitated holding of the crude petroleum oil. A series of measurements of electrical properties such as permittivity and physical properties such as density is collected. The density minima can be used to generate hindsight determinations of average properties, such as the dry oil phase density, which in turn can be used to increase the accuracy of the water percentage in the oil determined by the permittivity and density methods. Flow weighted averages of water percentages by each method can be used to determine and validate the water content of the crude petroleum oil.
