The article addresses an interesting yet unexplored issue in the development of surfactants for microemulsion stabilisation: the role of surfactant headgroup modification to tune the surfactant performances in CO2,water, and cyclohexane. The aqueous properties, and phase behaviour of novel tetrapropylammonum (TPA) surfactants is described. For comparison purposes, the related sodium surfactant (Na-AOT, Na-AOT4, and Na-TC14) are also used to form microemulsions. Observation on the surfactant aqueous properties revealed that the swapping into TPA does not significantly increases the effectiveness of the surfactant in lowering the surface air-water (a/w) tension. The introduction of bulky TPA counterions to normal sulfosuccinate surfactant generally leads to a transition from spherical micellar to extended sheet-like micellar aggregates in water. All in all, the results point minor effect on the headgroup structure modification towards the compatibility of surfactant with CO2.

Green enhanced oil recovery (GEOR) is a chemical enhanced oil recovery (EOR) involving the injection of specific green chemicals (surfactants/alcohols/polymers) that effectively displace oil because of their phase-behaviour properties, which decrease the IFT between the displacing liquid and the oil. Carbon nanoparticles application in EOR has sparked interest in the last few years due to its unique characteristics. Carbon nanotubes (CNTs) are one of the common carbon nanomaterials with EOR potential, but they are not used with green surfactant to improve oil recovery. In addition, the recently developed Date Leaf Carbon Particle (DLCP) method has not been applied to GEOR and requires further study. The role of carbon particles in GEOR is not well understood and requires further investigation. This study was conducted to examine the effectiveness of DLCP and CNT in green surfactant alkyl polyglucoside (APG) for recovering residual oil within rock pores. The study consisted of a set of laboratory experiments. Two formulations of DLCP, CNT and green surfactant mixtures were selected for core-flood experiments based on interfacial tension measurements to examine their potential for EOR. In the first formulation, 0.08% DLCP was mixed with 0.5% APG and produced 45% of tertiary oil and 89% of oil initially in place (OIIP). This formulation produced a significant quantity of incremental oil after water flooding. Lastly, 0.5% APG was blended with 0.08% CNT; this produced about 27% tertiary oil and 77% OIIP.

Chemical Enhanced Oil Recovery (cEOR) processes comprise a number of techniques whichmodify the rock/fluid properties in order to mobilize the remaining oil. Among these, surfactantflooding is one of the most used and well-known processes; it is mainly used to decrease the interfacialenergy between the phases and thus lowering the residual oil saturation. A novel two-dimensionalflooding simulator is presented for a four-component (water, petroleum, surfactant, salt), two-phase(aqueous, oleous) model in porous media. The system is then solved using a second-order finitedifference method with the IMPEC (IMplicit Pressure and Explicit Concentration) scheme. The oilrecovery efficiency evidenced a strong dependency on the chemical component properties and itsphase behaviour. In order to accurately model the latter, the simulator uses and improves a simplifiedternary diagram, introducing the dependence of the partition coefficient on the salt concentration.Results showed that the surfactant partitioning between the phases is the most important parameterduring the EOR process. Moreover, the presence of salt affects this partitioning coefficient, modifyingconsiderably the sweeping efficiency. Therefore, the control of the salinity in the injection water isdeemed fundamental for the success of EOR operations with surfactants.
