“…Most recent studies have focused on either betaine surfactants for their favorable performances in reducing the interfacial tension or homopolymers for their antipolyelectrolyte effects, whereas copolymers containing betaines that can similarly respond to salt have often been neglected. [35][36][37][38] In our previous work, a sulfobetaine copolymer consisting of AM, acrylic acid, and 2-f[2-(acryloyloxy)ethyl]dimethylammoniogethyl sulfite was successfully synthesized. 39 We found that this copolymer could do produce ionic interactions and retain a certain h app under high-salinity conditions; also, it showed outstanding antimicrobial ability.…”

In the process of oilfield development, salt tolerance is an important property for enhanced oil‐recovery (EOR) chemicals. In this study, we synthesized two acrylamide‐based sulfobetaine copolymers containing 2‐hydroxy‐3‐[(3‐methacrylamidopropyl)dimethylammonio]propane sulfonate (SHPP) or 3‐(4‐acry‐loyl‐1‐methyl‐piperazinio)‐2‐hydroxypropane sulfonate (SHMP). The interactions between these two copolymers and inorganic salts were compared, and the apparent viscosity (ηapp) behaviors of copolymer–salt solutions at different shear rates and temperatures were investigated. We found that the ηapp of PAPP and PAMP showed intensive antisalt performance, exhibiting an excellent antipolyelectrolyte effect. The ηapp retention value of 30,000 mg/L PAMP in brine was 86.47 mPa s at 510 s−1, and when the temperature was increased to 90 °C, it was 99.73 mPa s; this was better than that of PAPP under the same conditions. Therefore, PAMP was more applicable as an EOR chemical that have outstanding salt tolerance and temperature resistance. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2018, 135, 46235

“…[22][23][24] As expected, Gibbs energy for the micellization process is negative (spontaneous) for all temperatures, and increases slightly (less negative values) with temperature, indicating that spontaneity decreases with temperature within the temperature range evaluated. 3 shows the standard Gibbs energies of micellization at 298.15 K given in Table 4 (1) IFT, (2) EC, (3) 1 H NMR spectroscopy, (4) uorescence, (5) EMF. The effect of different counter-ions in micellization of typical surfactants has been explored to a limited extent.…”

Characterization and interfacial properties of the surfactant ionic liquid 1-dodecyl-3-methyl imidazolium acetate for enhanced oil recovery

The use of surfactant ionic liquids has recently gained attention for surfactant-based enhanced oil recovery.The introduction of the surfactant character in ionic liquids combines interesting properties of both types of chemicals, which are relevant for this application. An imidazolium-based surfactant has been synthesized combined with an acetate counter-ion. The aggregation effects in water were evaluated by means of surface tension and electrical conductivity. The dynamic interfacial tensions between the aqueous solutions of the surfactant ionic liquid and crude oil (Saharan blend) were evaluated by the spinning drop method. The effect of different variables has been analyzed, namely the concentration of surfactant ionic liquid, electrolytes (NaCl) and alkalis (NaOH, Na 2 CO 3 ), and temperature. Formulations of ionic liquids and alkalis were tested for the first time for enhanced oil recovery. The results obtained here improve significantly (at least one order of magnitude, most often two) previous results obtained up to now solely with ionic liquids.

“…Moreover, the alkali could corrode the stratigraphic texture to block stratigraphic reservoir channels . Although several systems with fixed‐design structures reduce the IFT to ultra‐low levels, they are impossible to apply large‐scale in oil fields due to the high cost …”

Performance of alkali‐free natural petroleum sulfonates: Ultra‐low interfacial tension on oil/water interface

et al. 2015

Ultra‐low interfacial tension (IFT) is one of the most important conditions relating to surfactant flooding for enhanced oil recovery. In this paper, the dynamic interfacial tension (DIT) of an alkali‐free petroleum sulfonate surfactant was studied with the spinning drop method aimed at the Daqing oil/water system. The effects of various experimental conditions, such as surfactant concentration, inorganic salt concentration, polar organic compounds, oil‐soluble sulfonates, and time stability were investigated. It was shown that the aqueous phase has little effect on DIT. The high molecular weight petroleum sulfonates play an important role in the lowering of oil/water IFT. The non‐uniform changes of the oil droplets in DIT measurements were also discussed from the aspects of petroleum sulfonate composition and diffusion rate. The increase of aqueous phase viscosity could only ease the rebound phenomenon, while the increase of heavy components of petroleum sulfonates could both eliminate the non‐uniform changes of the oil droplets and reduce the values of the IFT. These results may be helpful in explaining the reasons behind producing ultra‐low interfacial tension and the preparation of formulations for practical applications.
