... system is important. In this work, a systematic study was carried out on the use of an oil-in-water (O/W) Pickering emulsion stabilized by sodium (Na)-montmorillonite particles. The particle-size distribution and zeta potential of Na-montmorillonite particle solutions at 0 to 20 wt% sodium chloride (NaCl...

Trends in ES are also consistent in most cases with other field indicators of emulsion stability, such as high-temperature high pressure fluid loss. Anomalies in ES trends are explained in terms of a physicochemical...
