“…This sample differs from igneous 1 in that it does not have an all-negative surface charge value but has an isoelectric point. The isoelectric point is the pH at which the surface charge of a sample is zero. − It also depicts the pH value below and above which a sample shows opposite surface charges . The measured ζ-potential results (Figure A) show a lower magnitude of surface charge compared to the igneous 1 sample.…”

The reduction of carbon footprints is one of the steps being taken as the world looks for a solution to the difficulties caused by climate change. This will be accomplished by developing technologies that both consume and emit less carbon dioxide into the atmosphere. Other methods include mineralization or bulk storage of the captured gases in subsurface reservoirs. Mineralization involves the interaction of cation-rich rocks or fluids with carbonated water to form precipitates that ensure the safe disposal of CO2 that has been captured. To assess the viability of this route, numerous initiatives have been made as well as a few experimental projects. Understanding of the electrokinetic property of igneous rocks, which governs characteristics like wetting conditions and susceptibility to release cations, is, however, rare in the literature. Thus, to shed light on the electrokinetic behavior and colloidal stability of igneous rocks, this research has employed electrophoresis. This research revealed that igneous rocks are mainly negatively charged in both freshwater and saltwater environments. On the other hand, igneous rocks’ magnesium ion content significantly affects how they are charged, occasionally flipping the charge to positive and shifting the solution state from acidic to alkaline. This would have an even greater effect on the mineralization process and shorten the time needed for the reaction between igneous and CO2-rich fluids. This is inferred by the fact that the highest dissolution of metal cations is known to occur at pH values of 3 and 4. Furthermore, samples with a low magnesium content have stable colloidal stability, whereas samples with a high magnesium content are colloidally unstable. The samples’ colloidal stability also has a significant impact on how easily the cations needed for mineralization are released.

Chemical viscosity reduction and cold production technology has the characteristics of low cost, low energy consumption, and low emission, which makes it suitable for gradually replacing thermal production as the main development method of heavy oil reservoirs. Most of the existing evaluation processes of viscosity reducers used in chemical viscosity reduction and cold production adopt the dynamic method of preparing O/W emulsions by high-speed shearing. However, high-speed shearing cannot be achieved in the contact process between heavy oil and the viscosity reducer in porous media. There is only a weak seepage shear force, which makes heavy oil self-diffuse in the viscosity reducer solution. Therefore, the existing methods cannot accurately evaluate the self-diffusion performance of viscosity reducers under quasi-static conditions. In this work, a method for evaluating the self-diffusion performance of a heavy oil viscosity reducer based on UV–Vis absorption spectroscopy is proposed, and the influence of various factors on the viscosity reduction effect and self-diffusion performance of a viscosity reducer is investigated. The results show that there is a good correspondence between the viscosity reduction effect and the self-diffusion performance. The viscosity reducer concentration, oil content, temperature, and emulsification time have obvious effects on the self-diffusion performance of the viscosity reducer. Based on the results of the orthogonal experiment, a self-diffusion performance prediction model of the viscosity reducer is established. The verification experiment results show that the model has good applicability. This research provides a new idea for accurately evaluating the self-diffusion performance of viscosity reducers under quasi-static conditions.

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.
