Abstract: A micellar compositions including oil-soluble surfactants delivered by water-soluble surfactants are disclosed. The micellar compositions demonstrate enhanced crude oil mobilization in porous media. When the porous media was imbued with crude oil, the presence of the surfactant in the oil phase improved the mobilization performance of crude oil. Solutions of SDS were used to solubilize the surfactant, and the formation of SDS/PIBSI micellar composition was confirmed by Cryo-SEM images. High cleaning effectiveness of the micellar compositions on crude oil entrapped in porous media was demonstrated by image binarization.

Abstract: The present invention comprises a transparent and electrically conductive glass capillary for the purpose of containing and heating fluids inside the capillary on the stage of a microscope and a method to investigate and characterize acid neutralization by overbased additives in lubricant oils. The heating capillary was prepared by coating a transparent ITO film on the outside surface of the capillary as an electrically heating jacket. It can generate at least 287° C. when applied appropriate voltage. The desired temperature can be attained at a rate ranging from 75° C./s to 198° C./s and be easily adjusted by changing the supplied voltage.
