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.
