“…Recent studies show that NPs are able to improve the foam stability at severe reservoir conditions and subsequently oil recovery is improved. Inorganic oxide nanoparticles such as silica [176][177][178][179][180][181][182], Al 2 O 3 [183][184][185], carbonate [186], TiO 2 [182], CuO [182], and fly ash nanoparticles [187,188] have been evaluated in foam stabilization. In particular, Figure 20a shows the oil recovery through waterflooding before (Step 1) and after (Step 2) the injection of surfactant (PSCI) in the absence (PSC1) and presence (PSC1 + SiO 2 ) of SiO 2 nanoparticles [177].…”

The increasing demand for fossil fuels and the depleting of light crude oil in the next years generates the need to exploit heavy and unconventional crude oils. To face this challenge, the oil and gas industry has chosen the implementation of new technologies capable of improving the efficiency in the enhanced recovery oil (EOR) processes. In this context, the incorporation of nanotechnology through the development of nanoparticles and nanofluids to increase the productivity of heavy and extra-heavy crude oils has taken significant importance, mainly through thermal enhanced oil recovery (TEOR) processes. The main objective of this paper is to provide an overview of nanotechnology applied to oil recovery technologies with a focus on thermal methods, elaborating on the upgrading of the heavy and extra-heavy crude oils using nanomaterials from laboratory studies to field trial proposals. In detail, the introduction section contains general information about EOR processes, their weaknesses, and strengths, as well as an overview that promotes the application of nanotechnology. Besides, this review addresses the physicochemical properties of heavy and extra-heavy crude oils in Section 2. The interaction of nanoparticles with heavy fractions such as asphaltenes and resins, as well as the variables that can influence the adsorptive phenomenon are presented in detail in Section 3. This section also includes the effects of nanoparticles on the other relevant mechanisms in TEOR methods, such as viscosity changes, wettability alteration, and interfacial tension reduction. The catalytic effect influenced by the nanoparticles in the different thermal recovery processes is described in Sections 4, 5, 6, and 7. Finally, Sections 8 and 9 involve the description of an implementation plan of nanotechnology for the steam injection process, environmental impacts, and recent trends. Additionally, the review proposes critical stages in order to obtain a successful application of nanoparticles in thermal oil recovery processes.

The article describes the extraction of hydrocarbons as the main source of energy in the world that requires careful control. The control is achieved by means of the advanced technologies that ensure a more rational and efficient use of resources. Technologies that have received great development in related areas of industry have a great perspective for the development of any industry as a whole. The influence of convergent technologies on the advanced technologies in the oil industry has been stated. The impact of the convergent technologies development on the oil and gas complex in the world, as well as the main problems facing the field of hydrocarbon production have been considered. The trends in convergent technologies in oil and gas production are presented: nanotechnology, biotechnology, information technology. The main examples of implemented projects of convergent technologies directly in oil fields are considered. The main ways of introducing nano-, bio- and information technologies in the hydrocarbon industry have been identified, the typical cases of their application were defined, as well as the further prospect of introducing these technologies not only in formations, wells, but also at subsequent stages of the use of hydrocarbons.

“…Wet grinding is commonly used for production of mineral nanoparticles, and stirred ball mills are known to be most effective for nanoparticle production. The grinding set-up and its operation employed for fly ash nano-milling are described by Lee et al(2015) in detail. Grinding is usually conducted in two stages using two different types of stirred ball mills.…”

With design surface functionalization, nanoparticles can provide unique benefits for improved oil and gas production. Some applications recently developed at our laboratories are briefly reviewed. One example is the use of silica nanoparticles as foam stabilizers. Ultra-dry but stable CO 2 foams can be generated for CO 2 EOR mobility control and also as "waterless" fracturing fluids for unconventional reservoir development. Another innovative way of generating similar CO 2 foam is to use nano-milled fly ash as stabilizer. Fly ash being a waste product, the technique has the benefit of sequestering both CO 2 and fly ash. Magnetite nanoparticles are widely employed in medical and other industries because, with external magnetic field application, they can be detected remotely; selectively collected; or generate intense, localized heat. One example application is the removal of left-over chemicals from EOR processes, from oilfield produced water. Attached to nanoparticles, the chemicals can be collected and removed by magnetic separation.
