Experimental Study of Chemical Reduction on Interfacial Tension by Using Dodecyl Trimethyl Ammonium Bromide
Author(s): Elyas Golabi
Abstract: Surfactant flooding has the potential to significantly increase recovery over that of conventional water flooding. The availability of a large number of surfactant structures makes it possible to conduct a systematic study of the relation between surfactant structure and its efficacy for oil recovery. Also, the addition of an alkali such as sodium carbonate makes possible in situ generation of surfactant and significant reduction of surfactant adsorption. In addition to reduction of interfacial tension to ultra-low values, surfactants can be designed to alter wettability to enhance oil recovery. Therefore, using surfactant increases water imbibition process into the matrix, which increases oil recovery. In this paper the effects of dodecyl trimethyl ammonium bromide (DTAB), on the reduction of interfacial tension (IFT) between water and oil. Oil sample obtained from fracture carbonate reservoir in southern of Iran, was studied at the reservoir temperature. The results show that the DTAB surfactant at 0.8 wt% concentration reduced interfacial tension between oil and water until 1.23 mN/m.
