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.

The authors reported a noticeable increase in oil recovery due to reduction in mobility ratio and surface tension of displacing fluids and that IL used had the ability to improve the wettability of the rocks to become more water-wet [13].…”

Given the rise in oil productivity from conventional and unconventional resources in Canada using Enhanced Oil Recovery (EOR), the need to understand and characterize these techniques, for the purpose of recovery optimization, has taken a prominent role in resource management. Chemical flooding has proved to be one of the most efficient EOR techniques. This study investigated the potential of employing Ionic Liquids (ILs) as alternative chemical agents for improving oil recovery. There is very little attention paid to employing this technique as well as few experimental and simulation studies. Consequently, very limited data are available. Since pilot and field studies are relatively expensive and time consuming, a numerical simulation study using CMG-STARS simulator was utilized to explore the efficiency of employing 1-Ethyl-3-Methyl-Imidazolium Acetate ([EMIM][Ac]) and 1-Benzyl-3-methlimidazolium chloride ([BenzMIM][Cl]) with respect to improving medium oil recovery. Eight different lab-scale sandpack flooding experiments were selected to develop a numerical model to obtain the history matching of the experimental flooding results using CMG-CMOST. We observed that the main challenge was tuning the relative permeability curves to achieve a successful match for the oil recovery factor. Finally, a sensitivity study was performed to examine the effect of the chemical injection rate, the chemical concentration, the slug size, and the initiation time on oil recovery. The results showed a noticeable increase in the oil RF when injecting IL compared to conventional waterflooding.
