“…Surface-active ionic liquids (SAILs) are being extensively applied for EOR, their main advantages being their tunability and stability in harsh environmental conditions [ 109 ]. Only two papers have been recently published where the synergism of using SAILs and nanoparticles was exploited [ 110 , 111 ]. Stability and IFT studies were carried out to design a formulation consisting of 0.05 wt% Al 2 O 3 , 1.0 wt% PVP, 0.5 wt% 1-dodecylpyridinium chloride in brine 0.5 wt% NaCl.…”

“…The formulation achieved an EOR of 12 %OOIP in carbonate rocks, thus improving the results obtained using just the SAIL or the SAIL plus polymer [ 110 ]. The same methodology was used to design a stable formulation at higher salt content (5 wt% NaCl) [ 111 ]. With the SAIL 1-dodecyl-3-methylimidazolium chloride (0.05 wt%) and the same nanoparticle and polymer concentrations, an EOR of 14.8 %OOIP was achieved.…”

The use of nanofluids is showing promise as an enhanced oil recovery (EOR) method. Several reviews have been published focusing on the main mechanisms involved in the process. This new study, unlike previous works, aims to collect information about the most promising nano-EOR methods according to their performance in core-flooding tests. As its main contribution, it presents useful information for researchers interested in experimental application of nano-EOR methods. Additional recoveries (after brine flooding) up to 15% of the original oil in place, or higher when combined with smart water or magnetic fields, have been found with formulations consisting of simple nanoparticles in water or brine. The functionalization of nanoparticles and their combination with surfactants and/or polymers take advantage of the synergy of different EOR methods and can lead to higher additional recoveries. The cost, difficulty of preparation, and stability of the formulations have to be considered in practical applications. Additional oil recoveries shown in the reviewed papers encourage the application of the method at larger scales, but experimental limitations could be offering misleading results. More rigorous and systematic works are required to draw reliable conclusions regarding the best type and size of nanoparticles according to the application (type of rock, permeability, formation brine, reservoir conditions, other chemicals in the formulation, etc.)

“…Since then, surfactants such as petroleum sulfonate − as well as alkyl benzenesulfonate − and olefin sulfonate − have been widely used in enhanced oil recovery due to their good performances and economic advantages. Nanoparticle surfactants and interfacial active nanoparticles could contribute to reducing interfacial tension, forming pulse emulsification and wettability alteration in porous media, which have also gained attention for their potential applications in enhanced oil recovery. − However, those surfactants are limited in applications to high salinity reservoirs due to their poor salt tolerance.…”

A large variety of surfactants have been widely used in enhanced oil recovery, yet there is still a challenge for the application of surfactants in oil reservoirs with high salinity and high temperatures. Herein we report a new alkyl polyether benzyl sulfonate anionic surfactant named sodium iso-tridecanol polyoxyethylene ether benzyl sulfonate with ultralow interfacial tensions at high salinity and high temperatures synthesized through a strategy connecting the alkyl polyether with a benzyl group. Its structure was confirmed by 1 H NMR. Effects of the temperature, salinity, divalent ion, and surfactant concentration on interfacial tensions and phase behaviors were investigated. The alkyl polyether benzyl sulfonate surfactant demonstrated a strong interfacial activity and excellent phase behavior with high solubilization parameters at salinities up to 18.0 wt % NaCl and temperatures up to 120 °C, which suggest that the new alkyl polyether benzyl sulfonate surfactant has good temperature resistance and salt tolerance and is promising for applications in enhanced oil recovery in high temperature and high salinity oil reservoirs.

Review on Applications of Ionic Liquids (ILs) for Bitumen Recovery: Mechanisms, Challenges, and Perspectives

Water- and solvent-based ex situ extraction processes have been employed to extract bitumen from mineable oil sands. On the other hand, bitumen is recovered in situ from deeper deposits most efficiently by injecting steam to reduce viscosity and increasing production flow to the surface. However, the water-based process with or without solvent (including steam injection) is not sustainable due to various challenges including water requirement and treatment, high energy consumption, and related environmental pollution problems emanating from high volatility of solvents. Ionic liquids (ILs) have become desirable in several industrial applications due to many unique properties including low volatility compared with traditional organic solvents. The potential for application of ILs for bitumen extraction is reviewed in this work, with a focus on the mechanistic aspect. Depending on the properties and/or functionality, the ILs can be used in bitumen extraction (with or without organic solvents) with minimal clay fines contamination and lower water and energy requirements. In the solvent-assisted IL recovery system, the IL–clay interaction is responsible for reducing the adhesive force between bitumen and the sand, which subsequently facilitates separation. Conversely, considering the types of ILs explored in the absence of solvent, the IL–bitumen interaction plays an additional role. Hitherto, applications of ILs in bitumen recovery are at a very preliminary stage. Apart from understanding the mechanisms, the major impediment lies in the high cost and environmental impact due to toxicity. Therefore, to make ILs more attractive for bitumen recovery, concerted efforts should be intensified to reduce the cost of producing ILs, ameliorate environmental impacts, and facilitate field scale applications through technoeconomic analysis of the process.
