Impacts of Temperature and Surfactant on Wettability in Mineral-Oil-Water Systems.

ABSTRACT: Mineral wettability is a crucial factor that determines the distribution of oil and water at the pore scale and, thus, influences oil reserves and recovery efficiency at the reservoir scale. Adding surfactants is one of the most common methods used to modify mineral wettability. However, previous studies on modifying mineral wettability via surfactants were mainly performed under room-temperature conditions, which do not represent the high-temperature reservoir conditions. A systematic investigation of the effects of temperature and surfactant on wettability in mineral-oil-water systems is still lacking. Therefore, in this study, the impact of temperature (25 °C vs 50 °C), surfactant type (cetyltrimethylammonium bromide [CTAB] vs sodium dodecyl sulfate [SDS]), and concentration (0-0.2 wt %
