“…On the one hand, nonthermal EOR methods constitute nearly 33% of the EOR projects worldwide and primarily stem from the principles of chemical-enhanced oil recovery (cEOR), originally developed for conventional oil reservoirs . Among the spectrum of nonthermal EOR approaches, chemical flooding holds prominence, including the utilization of surfactants (e.g., closed-cycle oil recovery, C–COR), polymers, alkaline, or a blend thereof, i.e., alkali–cosolvent–polymer (ACP) or alkali–surfactant–polymer (ASP). , Additionally, nonthermal methods involve the injection of miscible and immiscible gases, encompassing the use of CO 2 and N 2 for both immiscible and miscible flooding scenarios. , Comparatively, thermal EOR which accounts for more than 50% of the worldwide EOR projects, harnesses thermal energy to elevate the reservoir temperature, thereby encompassing a spectrum of remarkable physicochemical effects, including the simultaneous reduction of oil viscosity, interfacial tension, and increased API gravity . Moreover, these processes stimulate chemical transformations such as cracking, dehydrogenation, oxidation, and other reactive modifications that facilitate the seamless flow of oil toward the production well.…”

The increase in energy demand and the dynamics of the energy transition have changed the perspectives and opportunities within the oil and gas sector. This revolutionary scenario has resulted in sustainable and consolidated strategies, exemplified by the development of enhanced oil recovery (EOR) methods within the improved oil recovery (IOR) scheme, and specifically for this Review study in the steam-assisted gravity drainage (SAGD) techniques. The selection and impact of the EOR methods, as well as the expected recovery, rely on multiple factors, encompassing economic, environmental, and technological considerations. The above has led to the simultaneous appearance of uncertainties and difficulties that are continuously challenging the ranking of the oil sector in the global energy market. Against this background, nanotechnology has been established as a feasible strategy to be integrated into multiple stages of the oil supply chain. This Review study has focused on highlighting the synergistic trends of nanotechnology, steam, and oil recovery by conducting bibliometric analysis, where a tendency of the number of publications has increased in the last three years, as evidence of the application of nanotechnology in the oil industry. We have also carried out comprehensive discussions on the most widely implemented conventional thermal oil recovery methods with the dual purpose of explaining their methodologies and, at the same time, highlighting their inherent limitations and the imperative requirements to optimize them. In this direction, we have presented an in-depth exploration of the physicochemical mechanisms of action of nanoparticles to underscore the prospects for their applications in the EOR technologies. Finally, we contextualized the economic and technical feasibility of incorporating nanoparticles into industry, alongside advancements in simulation studies, presented as robust and cost-effective research alternatives, offering a more well-founded perspective on the scalability of nanoparticle technology.

“…With the continuous exploitation of global oil resources, oil extraction has entered the tertiary stage to extract heavy and ultraheavy oil. As a result of surveys, the global share of heavy and superheavy oil accounts for 40% of proven reserves, exceeding that of conventional light oil reserves [1,2]. Moreover, globally, the recoverable resources of heavy oil account for 29% of unconventional oil and gas [3].…”

Since there are not many studies on the application of polymeric surfactants in viscosity reduction emulsification of heavy oil, a series of polyether carboxylic acid–sulfonate polymeric surfactants were synthesized. The viscosity reduction performance and the effect of different chain lengths on the viscosity reduction effect were also investigated. The viscosity reduction, emulsification, wetting, and foaming performance tests showed that the viscosity reduction performance of this series of polymeric surfactants was excellent, with the viscosity reduction rate exceeding 95%, and the viscosity was reduced to 97 mPa·s by the polymeric surfactant with a molecular weight of 600 polyethers. It was also concluded that among the three surfactants with different side chains, the polymeric surfactant with a polyether molecular weight of 600, which is the medium side-chain length, had the best viscosity reduction performance. The study showed that the polyether carboxylic acid–sulfonate polymer surfactant had a promising application in the viscosity reduction of heavy oil.
