“…Although the thermal recovery of heavy crude oil with nanoparticles is a relatively new technology, this has been widely investigated [23,30,44,[50][51][52][53][54]. However, to the best of our knowledge, there is no detailed information in the scientific literature on the influence of nanomaterials for the upgrading of heavy and extra-heavy crude oils in enhanced thermal recovery techniques.…”

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 NiO‐NP also decreased the AE during pyrolysis and radical polymerization, resulting in a broad temperature interval where these reactions can take place. As discussed by Amanam and Kovscek, the excessive fuel deposit is the critical problem undesired for heavy oil combustion . The benefits can be gained by interfering fuel deposition with NiO‐NP in the ISC process of heavy crudes.…”

Summary Nickel oxide nanoparticles were synthesized by microemulsion method and characterized by powder X‐ray diffraction, dynamic light scattering, and scanning electron microscopy. Thermal analyses were performed to identify the influence of nickel oxide nanoparticles on the in situ combustion of Liaohe heavy oil. Low‐temperature oxidation and coking process were investigated by analysing the effluent gases and the fractions of saturates, aromatics, resins, and asphaltenes. Combustion tube tests were also conducted to evaluate the catalytic performance of nickel oxide nanoparticles. Compared with the runs without catalysts, the effective activation energies were reduced by 4.22%, 20.57%, and 35.75% in terms of low‐temperature oxidation, pyrolysis, and high‐temperature oxidation, respectively. The reduction in O2 fraction and the increase in CO2 and O2 uptake were also confirmed. The overall trend presented the increase of saturates and aromatics fraction and the decline of resins and asphaltenes fraction while temperature was increased during low‐temperature oxidation. Adding nickel oxide nanoparticles led to the reduction in the fuel deposit during pyrolysis. Compared with the base combustion tube runs, combustion time in catalytic experiment was shortened by 12.1%, combustion front movement was accelerated by 9.1%, oil recovery was enhanced by 4.0%, and oil viscosity was reduced by 61.2%.

Air flooding is a potential enhanced oil recovery (EOR) method to economically and efficiently develop a tight oil reservoir due to its sufficient gas source and low operational costs, during which low temperature oxidation (LTO) is the key to ensuring the success of air flooding. In addition to inefficiency of conventional LTO, air flooding has seen its limited applications due to the prolonged reaction time and safety constraints. In this paper, a novel air injection technique based on the catalyst-activated low temperature oxidation (CLTO) is developed to improve the operational safety together with its oil recovery in tight oil reservoirs. Experimentally, static oxidation experiments are conducted to examine the influence of the catalyst on the LTO reaction kinetics of Changqing tight oil and its fractions. The catalytic oxidation characteristics are identified by applying a thermogravimetric analyzer coupled with Fourier transform infrared spectrometer (TG-FTIR) with respect to tight oil and its SARA (i.e., saturates, aromatics, resins, and asphaltenes) fractions. Accordingly, the catalyst can obviously decrease the LTO reaction activation energy of the Changqing tight oil and its SARA fraction. Cobalt additive can change the LTO reaction pathways of the SARA fractions, i.e., promoting the formation of hydroxyl-containing oxides and CO 2 from the oxidation of saturates, aromatics and resins, while inhibiting the formation of ethers from the oxidation of aromatics and resins. The LTO of each SARA fraction contains both oxygen addition reaction and bond scission reaction that can be effectively promoted with the cobalt additive. The catalytic effect on the bond scission reaction is continuously enhanced and becomes gradually stronger than that on the oxygen addition reaction as the reaction proceeds.
