Asphaltenes, complex aromatic components in crude oil, can precipitate under changing conditions, causing significant challenges in oil production and processing. This precipitation increases operational costs, making the development of effective inhibition methods crucial for the petroleum industry. This study investigates asphaltene precipitation reduction using salicylic acid and TiO2 nanofluids. The optimal mixture composition was found to be 75% salicylic acid and 25% TiO2. In addition, the research examines the effects of inhibitor concentration and temperature on performance. Lower temperatures (25°C) yield higher asphaltene precipitation reduction, with decreasing effectiveness as temperature rises to 70°C. The study also explores the inhibitor’s impact on oil viscosity across various temperatures. The 75% salicylic acid and 25% TiO2 mixture slightly reduces oil viscosity compared to pure salicylic acid, potentially benefiting oil production and transportation processes. Furthermore, this optimal mixture demonstrates superior performance in reducing asphaltene particle size, achieving a 60% reduction compared to no inhibitor and a 32% reduction compared to salicylic acid alone. This significant particle size reduction could have substantial implications for preventing asphaltene precipitation and aggregation in oil production and processing, potentially improving overall efficiency and reducing operational challenges
