Indonesia still demands huge amount of imported oil. This could happen because Indonesia is still using primary and secondary method for taking oil. One of the methods that has not been maximized is a tertiary method which is Enhanced Oil Recovery. This method can be done by chemical injection which is polymer, alkali, surfactants or polymeric surfactant. Surfactants (surface active agent) can modify the interfacial tension of fluids that are not soluble. One of the surfactants that can be used is Sodium Lignosulfonate (SLS). In the existing study, SLS surfactants have been widely made with raw materials such as empty palm and pine bunches. In this research, there are 3 new polymeric surfactants from black liquor and polyethylene glycol with different weight ratio; PS1 (1:1), PS2 (1:0,8), and PS3 (1;0,5). All products passed compatibility test and thermal stability test also there is a slight increase in viscosity. EOR application by core flooding test was done to each polymeric surfactant. The test showed that the best recovery is from PS3 (11%) and the IFT for PS3 is 4×10−1 dyne/cm. [ABSTRACT FROM AUTHOR] |
