Abstract
Methods of evaluating a surfactant may include ultrasonicating a mixture of oil, water, and the surfactant to form at least one of the following: a sub-macroemulsion, a macroemulsion phase or a combination of the aforementioned; separating the sub-macroemulsion from the macroemulsion phase; introducing the sub-macroemulsion into a foam container; performing a first automated phase identification of the sub-macroemulsion; introducing a gas into the sub-macroemulsion to generate a column of foam, where the column of foam has a height in the foam container; performing a second automated phase identification of the sub-macroemulsion; and measuring the height of the column of foam in the foam container. In these methods, the first and second automated phase identifications may be configured to quantify one or more liquid phases and a foam phase in the column.
