“…Oil and gas exploitation companies have invested substantially in increasing the recovery and productivity of mature reservoirs, especially in enhanced oil recovery (EOR) processes (Lee et al, 2015;Pons-Jiménez et al, 2015;Romero-Zerón and Kittisrisawai, 2015). In EOR process, surfactant/polymer solution is injected through an injection well into an oil reservoir.…”

“…During the experiment, every ten ml of effluent were collected and analyzed by TOC detection for the surfactant-only injections or by UV–Vis spectrophotometry at 400 nm in the case of nanoparticles injection. The active substance content in the effluents allowed to plot the breakthrough curves, i.e., the relative concentration C / C 0 ( C —concentration in the effluent and C 0 —initial concentration injected) as a function of the pore volume [11,33]. Besides, to evaluate the content of adsorbed material in the medium, a graph of cumulative content recovered versus the pore volumes injected was obtained.…”

The aim of this study is the evaluation of partially sulfonated polystyrene nanoparticles (SPSNP) efficiency as nanocarriers for a non-ionic surfactant, oleic acid diethanolamide (OADA), in the reduction of the surfactant losses and the increase of oil recovery. The synthesized oleic acid diethanolamide was characterized by FTIR, 1H NMR, 13C NMR, surface tension (γ = 36.6 mN·m−1, CMC = 3.13 × 10−4 M) and interfacial tension of mineral oil/OADA aqueous solutions (IFTeq = 0.07 mN·m−1). The nanoparticles (SPSNP) were obtained by emulsion polymerization of styrene, DVB and sodium 4-styrenesulfonate (St-S) in the presence of OADA aqueous solution and were characterized by FTIR and PCS. The results show that the presence of ionic groups in the polymer structure promoted a better nanoparticles suspensions′ stability, smaller particles production and more pronounced IFT reduction. The SPSNP obtained with an OADA concentration twenty times its CMC and 0.012 mol % of St-S presented a particle size around 66 nm and can act as efficient nanocarriers decreasing the water/oil interfacial tension to low values (0.07 mN·m−1) along the time, when in contact with the oil. Transport and oil recovery tests of the nanocarriers systems in an unconsolidated sand porous medium test show that the SPSNP do inhibit surfactant adsorption onto sand particles surface and induced an increase of oil recovery of up to about 13% relative to the water flooding oil recovery, probably due to a synergistic effect between the nanoparticles and surfactant action at the water/oil interface.

“…In the field of EOR, β-CD has been applied as an additive to modify the wettability of the porous media, , to formulate polymer/β-CD/surfactant systems for polymer flooding as mobility control agents, − and for the encapsulation of surfactants as surfactant carrier systems for surfactant flooding − to advance oil recovery. Readers are referred to refs , , and − and references therein for further details. Even though more research on the use of cyclodextrins for EOR applications is justified to gain more insights on this area of study, this body of research demonstrates the feasibility of cyclodextrins as advantageous additives for EOR.…”

In this work, the issue of surfactant adsorption (SA) onto solid surfaces was attempted through surfactant encapsulation via host−guest interactions using β-CD. Formulations of a nonencapsulated surfactant system (Non-ESS) and an encapsulated surfactant system (ESS) were obtained through phase behavior analysis. Rheology shows that the ESS and Non-ESS display low viscosities, shear-thinning flow behavior, and structural stability. The ESS and Non-ESS were applied as surfactant flooding for enhanced oil recovery via coreflooding displacement tests to evaluate their performances in displacing and recovering residual oil. Static and dynamic SA tests of the ESS and Non-ESS were conducted. The experimental results demonstrate the effective propagation of both systems through the sand-packs. At the same flooding conditions, the ESS produced 63% higher incremental oil recovery than the Non-ESS, which confirms a reduced SA and effective surfactant release from the β-CD in the presence of oil. The static SA tests indicate that the ESS reduced SA by 82.42%, 60.59%, and 6.73% onto sand, kaolin, and shale respectively, relative to the Non-ESS. Likewise, the dynamic SA tests demonstrate that the ESS reduced SA onto sand−kaolin surfaces by 43.3% relative to the Non-ESS. Consequently, the ESS shows potential for applications where SA onto solid surfaces is a critical issue.
