During the past half-century, the prefix "nano" attached to several words, such as "technology", "motors", "device", and so on has denoted cutting-edge research fields and topics at the forefront of classical scientific disciplines. Possible application fields have been frequently evoked, even if real-life examples are still difficult to find. The present review analyzes how nanotechnology is utilized in enhanced oil recovery (EOR) processes so as to increase the efficiency of mature oilfields. Nanotechnology in EOR is classified into three categories: nanoparticles/nanofluids, nanoemulsions, and nanocatalysts. The advantages at the nanoscale are also described and discussed, including an overview of manufacturing methods as well as the concerns about their possible environmental impacts. Clearly, nanotechnology has the potential to boost EOR techniques, although there are still many questions and drawbacks to be tackled.

“…With this method, more heavy components of heavy oil are pyrolyzed to small molecules, and the viscosity of heavy oil reduced irreversibly eventually. These changes benefit the heavy oil exploitation [7][8][9][10][11][12][13][14][15][16]. This method is called "catalytic aquathermolysis".…”

“…Steam-injection, as a conventional method of exploitation, relying on the function of high-temperature steam, can only reduce the viscosity of heavy oil physically, with fewer changes of heavy components and lower viscosity reduction [4][5][6]. However, it will get a better result to add a suitable catalyst to catalyze the aquathermolysis.…”

“…Consequently, not only the physical properties of heavy oil will change, but also some hazardous gases will be generated. 7 In particular, hydrogen sulde (H 2 S) at extremely high concentrations has been observed in some oil elds, which threatens the safety of production equipment and workers. 8 Currently, it has been pointed out that H 2 S is generated through aquathermolysis reactions.…”

“…9 However, aquathermolysis is a very complex reaction, and the production mechanism of H 2 S is not fully understood. 7 Hyne et al rst carried out the aquathermolysis test using two heavy oil samples at 200-300 C. 10 During the steam injection process, the condensation, ring-opening, hydrodesulphurization, and water gas shi reactions occurred between steam and heavy oil; the composition of the gas obtained from the heavy oil reaction was the same as that of the gas obtained from sulfur-containing model compounds such as thiophene and thiolane. The aquathermolysis reaction is very complicated such that a number of aquathermolysis experiments have been conducted to investigate the inuencing factors for H 2 S generation via the aquathermolysis of heavy oil.…”
