“…However, it also can be seen from Figure 1 that all these traditional EOR processes face some important challenges. For example, for gas methods, the injected gas often quickly penetrates through reservoirs from injection wells to producing wells, resulting in a large amount of residual oil remaining uncovered in reservoirs because of the high mobility ratio of injected gas and oil [10,11]. Moreover, chemical processes are often limited by the high cost of chemicals, possible formation damages, and losses of chemicals [12,13].…”

Abstract:The injected fluids in secondary processes supplement the natural energy present in the reservoir to displace oil. The recovery efficiency mainly depends on the mechanism of pressure maintenance. However, the injected fluids in tertiary or enhanced oil recovery (EOR) processes interact with the reservoir rock/oil system. Thus, EOR techniques are receiving substantial attention worldwide as the available oil resources are declining. However, some challenges, such as low sweep efficiency, high costs and potential formation damage, still hinder the further application of these EOR technologies. Current studies on nanoparticles are seen as potential solutions to most of the challenges associated with these traditional EOR techniques. This paper provides an overview of the latest studies about the use of nanoparticles to enhance oil recovery and paves the way for researchers who are interested in the integration of these progresses. The first part of this paper addresses studies about the major EOR mechanisms of nanoparticles used in the forms of nanofluids, nanoemulsions and nanocatalysts, including disjoining pressure, viscosity increase of injection fluids, preventing asphaltene precipitation, wettability alteration and interfacial tension reduction. This part is followed by a review of the most important research regarding various novel nano-assisted EOR methods where nanoparticles are used to target various existing thermal, chemical and gas methods. Finally, this review identifies the challenges and opportunities for future study regarding application of nanoparticles in EOR processes.

In this study, micromodel tests were performed to investigate the microscopic flow behavior during primary production and the subsequent CO2 huff and puff. A series of 12 tests was conducted in sandpacks to evaluate the effects of the injection and production parameters on the displacement efficiency of the CO2 huff and puff. The micromodel tests and sandpack tests showed that the flow characteristics of CO2 huff‐and‐puff process was significantly affected by the pressure of converting the solution gas drive to the subsequent CO2 huff and puff. A foamy oil flow could be more easily formed in the production period of the CO2 huff and puff with a higher conversion pressure. Foamy oil can reduce the mobility of gas and provide tremendous energy to the system, thereby improving the performance of the CO2 huff and puff. The sandpack flood results show that the oil recovery of the solution gas drive decreased as the conversion pressure increased, whereas the oil recovery of the CO2 huff and puff increased as the conversion pressure increased. The highest total oil recovery was obtained at the pseudo‐bubblepoint pressure. The oil recovery of the CO2 huff and puff increased as the CO2 injection pressure and pressure decline rate increased. The oil recovery of CO2 huff and puff increased with the soaking time, and it exhibits a significant change when the soaking time ranges from 10 h to 24 h; above this value, the increase become slight. © 2015 Society of Chemical Industry and John Wiley & Sons, Ltd

“…Enhanced oil recovery is a tertiary method designed to recover the remaining oil left in a particular reservoir after primary and secondary methods are exhausted [1][2][3][4][5]. The nature and location of reservoir placement in the subsurface makes it difficult to estimate the amount of remaining oil and the position of mobilized oil in the reservoir.…”

In the current study, we developed an adaptive algorithm that can predict oil mobilization in a porous medium on the basis of optical data. Associated mechanisms based on tuning the electromagnetic response of magnetic and dielectric nanoparticles are also discussed. This technique is a promising method in rational magnetophoresis toward fluid mobility via fiber Bragg grating (FBG). The obtained wavelength shift due to Fe3O4 injection was 75% higher than that of dielectric materials. This use of FBG magneto-optic sensors could be a remarkable breakthrough for fluid-flow tracking in oil reservoirs. Our computational algorithm, based on piecewise linear polynomials, was evaluated with an analytical technique for homogeneous cases and achieved 99.45% accuracy. Theoretical values obtained via coupled-mode theory agreed with our FBG experiment data of at a level of 95.23% accuracy.
