1. A method comprising:
measuring, via a tensiometer, an oil and water field sample that comprises an added candidate demulsifier;
generating tensiometer data via the tensiometer based on the measuring of the oil and water field sample that comprises the added candidate demulsifier;
transmitting the tensiometer data from the tensiometer to a demulsifier analysis framework;
receiving, by the demulsifier analysis framework, the tensiometer data for the oil and water field sample that comprises the added candidate demulsifier, wherein the tensiometer data comprise rheology data with respect to frequency and wherein the demulsifier analysis framework comprises a model derived at least in part on bottle test data for demulsifiers in oil and water emulsions;
determining a performance characteristic for the added candidate demulsifier with respect to the oil and water field sample using the tensiometer data as input to the model of the demulsifier analysis framework without performing a bottle test on the oil and water field sample; and
outputting, by the demulsifier analysis framework, the performance characteristic for the added candidate demulsifier with respect to breaking an emulsion of the oil and water field sample.
