Abstract
The present invention addresses to a method for characterizing water produced in oil samples containing water with contents below 0.5%, by measuring the analytes of interest directly in the oil containing the emulsified water. For this, it is necessary to carry out filtrations to remove possible suspended solids, since they may interfere with the composition of the water. The method proposed in the present invention provides methodologies with and without interference in the equilibrium by washing the oil with distilled water, measuring the analytes of interest directly in the oil.
