Discussion

This analysis demonstrates how asphaltene affects emulsion stability under varying temperature and salinity, influencing oil recovery processes.

A water content of 30% provides the most stable emulsion, revealing the pivotal role of asphaltene at this concentration.
Increasing asphaltene concentration reduces droplet size significantly, enhancing phase separation resistance in emulsions.
Under high-pressure conditions, emulsion stability improves initially but decreases with excessive pressure due to asphaltene precipitation.
Temperature increases destabilize emulsions, highlighting the critical influence of thermal conditions in oil recovery scenarios.

Jahani et al. (2025) studied this question.
