In Situ Prepared Microemulsion-polymer Flooding in Enhanced Oil Recovery—A Review

“…In the comment/remark column, we have summarized significant remarks, observations, or criticism pertaining to the specific reference or article. In short the following useful information could be obtained from Table 1: • Anionic surfactants were often employed in in situ prepared microemulsions techniques and often produce promising results (Glinsmann, 1979;Bae and Petrick, 1981;Gupta, 1982;Sanz and Pope, 1995;Austad and Taugbøl, 1995a;Austad and Taugbøl, 1995b;Taugbøl et al, 1995;Austad et al, 1997;Levitt et al, 2006;Bouabboune et al, 2006;Zhao et al, 2008). These surfactants could significantly reduce the IFT of the fluid system tested.…”

“…IFT values as low as 10 −3 were measured and reported. • Surfactant retention in porous media has been a serious issue in the application of anionic surfactants (Glinsmann, 1979;Bae and Petrick, 1981;Gupta, 1982;Austad et al, 1997). Therefore, different techniques were used to eliminate or reduce the surfactant retention or recover the surfactant after its adsorption.…”

“…Therefore, different techniques were used to eliminate or reduce the surfactant retention or recover the surfactant after its adsorption. Among the techniques tested were injection of sacrificial agents prior to the microemulsion slug (Glinsmann, 1979), injection of a desorbing nonionic agent after the microemulsion slug (Minssieux, 1987), and injection of xanthan simultaneously with the microemulsion (Austad et al, 1997). • Another challenge often observed during in situ prepared microemulsion flooding is the formation of emulsions or macroemulsions (Kraft and Pusch, 1982;Bragg et al, 1982;Sanz and Pope, 1995).…”

Evaluation the performance of sodium metaborate as a novel alkali in alkali/surfactant/polymer flooding

“…To keep the free surfactant at essential concentration under high surfactant adsorption ratio, the surfactant cost will increase. The [19,20]. To reduce the surfactant adsorption, repulsion forces between the rock and surfactant should be generated.…”

Chemical Flooding in Naturally Fractured Reservoirs: Fundamental Aspects and Field-Scale Practices

“…These factors include the surfactant types (Hayes et al, 1979), chemistry (Enedy et al, 1982;Hirasaki et al, 1983;Krumrine et al, 1982), phase behavior (Glover et al, 1979;Novosad, 1982), chemicals adsorption (Austad et al, 1997), surfactant precipitation and redissolution (Somasundaran et al, 1984), chromatographic separation of chemicals (Li et al, 2009), surfactant convection (Ramirez et al, 1980), surfactant stability (Handy et al, 1982), chemicals loss (Friedmann, 1986), dispersion (Hirasaki, 1981), surfactant systems formulation (Salager et al, 1979), wettability , reservoir rock structure and morphology (Dullien et al, 1972;Yadali Jamaloei and Kharrat, 2009;Yadali Jamaloei et al, 2011a), and reservoir heterogeneity (Ma et al, 2007). The morphology and heterogeneity of the reservoir rock play a significant role in the behavior of chemical flooding processes.…”
