- This paper is a review of our work with Scheludko–Exerowa thin liquid film—pressure balance technique TLF-PBT, the first systematic application of the technique to petroleum systems. New insights were gained in understanding the behavior of petroleum emulsions. We have observed new phenomena in foam films stabilized with sodium naphthenates: long range foam film stratifications and step-wise film thickening at constant capillary pressure. Our modification of TLF-PBT cell allows probing water-in-oil emulsion films with electrical signal, a new technique to study water-in-oil emulsions.
