Synthesis, characterization and evaluation of a novel asphaltene inhibitor to control organic solid deposition in petroleum formation

This research work deals with synthesis of N-phenylamino hexanol tetramer to be used as an asphaltene inhibitor for crude oil in pores of reservoir. The synthesized additive was characterized using FTIR and Proton NMR spectroscopy, which confirms the formation of tetramer. Asphaltene deposition in the pores of sandstone core is studied by flooding the virgin and additive beneficiated crude oil indicating less deposition in beneficiated crude oil. Wettability alteration studies showed less contact angle hysteresis for virgin crude oil compared to the synthesized inhibitor beneficiated crude oil, which also aids to the lesser deposition of solid in the later one.
