| Abstract: | A systematic study has been performed employing the use of a cationic
surfactant didodecyldimethylammonium bromide (DDAB), an anionic surfactant sodium
lignosulfonate (SLS) and water for Enhanced Oil Recovery (EOR) from the
underground porous media of the depleting oil field of Naharkotiya, Duliajan,
in the Upper Assam basin, India. The strong electrostatic interaction between
the oppositely charged head groups present in cationic/anionic surfactant
mixtures, the geometric packing ratio can effectively be tailored by varying
the ratio of cationic and anionic surfactants. Here the behaviour of aqueous
mixtures of the surfactants, SLS and DDAB with reference to Interfacial Tension
(IFT) and EOR has also been explored. The zeta (ζ)-potentials are positive at DDAB-rich regions and negative at
SLS-rich regions. The vesicles appear to be stable, supported by large absolute
values of ζ-potentials and little
change in UV absorbance for several months.These vesicles can recover 46.45% oil
from water flooded porous media compared to micelles of SLS and DDAB, which can
recover 16.76% and 36.80% of oil respectively |
