Description
Summary:The process of injecting carbon dioxide (CO 2 ) into oil reservoirs involves intricate interactions between the reservoir’s hydrocarbons and CO 2 , resulting in changes to various physiochemical properties such as interfacial tension (IFT) between complex acidic hydrocarbons and CO 2 . The IFT plays a crucial role in enhanced oil recovery by altering capillary force. Hydrocarbon mixtures usually contain a percentage of acidic organic compounds that pose a crucial effect on IFT measurement. In this study, benzoic acid was chosen as a representative of acidic compounds to study the effect of acid number (0.0–0.8 g/L) on the IFT between CO 2 and different combinations of diesel fuel (representing aliphatic hydrocarbons) and gasoline (representing aromatic hydrocarbons). The volume ratios of the mixtures were varied at 0:100, 25:75, 50:50, 75:25 and 100:0%. Results revealed that increasing the acid number in gasoline from 0.2 to 0.8 g/L led to a significant change of more than 10 dyne/cm in the IFT between aromatic hydrocarbons and CO 2 . On the other hand, IFT alteration for aliphatic hydrocarbons was observed to be up to 5 dyne/cm. A new correlation for estimating IFT between CO 2 and different hydrocarbons was also proposed with an average relative error of less than 9%.
