Experimental Investigation of the Effect of using Nanoparticles for Improved Oil Recovery
International journal of petroleum and petrochemical engineering, 2018
Oil and gas companies are racing towards increasing production in their fields. As the well's first stage of production through natural flow is completed, much of the effort is focused towards improved oil recovery. This is the application of diversified techniques with the purpose of improving the recovery factor of hydrocarbons. As varied techniques are readily available, we employ a novel method towards enhance oil recovery by utilizing nanoparticle materials that can complement current techniques used in the field. The use of nanoparticle material homogenously mixed with surfactants alters the properties of hydrocarbons sweeping from pore throats of the reservoir. This mechanism greatly affects interfacial tension, wettability through the contact angle and the capillary pressure of hydrocarbons. Any rise in the recovery can obviously increase production rates, recover additional reserves and ultimately substantial economic gains. This research demonstrated that employing nanoparticles to complement EOR operation can be a promising method to be further studied and developed and later introduced to the oil industry.

Literature Review of Nanotechnology in the Enhanced Oil Recovery
Journal of Engineering Research
In recent studies, there has been an increasing focus on Nanoparticles Enhanced Oil Recovery (NPEOR). NPEOR is a method that was initially developed to improve microscopic and macroscopic displacement efficiency. In some recent applications NP have been assisted the conventional EOR methods such as a polymer, surfactant, and Co2 flooding, with the purpose of increasing the oil recovery. In this literature, the abilities to use NP in EOR are investigated. The function of different types of NP, different types of Dispersing agents, availability of nanomaterials in the lab, the effect of nanoparticles to change the properties, future challenges and concerns about the NP, are reviewed. However, the stability of suspensions of NP is still the most barrier to use NP in EOR. Upcoming studies are necessary to focus on the outcome of the appropriate techniques of NP to improve their stability under the worst conditions of reservoirs and investigate new types of nanoparticles.

Chemicals are a pivotal part of many operations for the oil and gas industry. The purpose of chemical application in the subsurface reservoir is to decrease the mobility ratio between the displaced fluid and the displacing one or to increase the capillary number. These have been the favorable mechanisms for Enhanced Oil Recovery (EOR). Recently, it became a mainstay with EOR researchers looking for effective and efficient materials that can be economically feasible and environmentally friendly. Therefore, when the development of chemicals reached a peak point by introducing nanosized materials, it was of wondrous interest in EOR. Unlike other sizes, nanoparticles display distinct physical and chemical properties that can be utilized for multiple applications. Therefore, vast amounts of nanoparticles were examined in terms of formulation, size effect, reservoir condition, viscosity, IFT, and wettability alteration. When a holistic understanding of nanoparticles is aimed, it is necess...

As many oil fields go into their final stage of production, novel technologies are necessary in order to maintain the production and increase the recovery of hydrocarbons. Therefore, advanced technology like Nanotechnology should be coming to overcome the problem of low recovery from reservoirs. Nano fluids were injected as a tertiary recovery method following a secondary water flooding. The experiments were performed at ambient conditions. Interfacial tensions and contact angles were measured in order to help explain the underlying mechanisms behind the increased recovery. In this research paper, the effect of silica nano and carbon nano particles on the wettability alteration in one of the Iran Sand Stone reservoir is mentioned. The results obtained from experiments show that these nano particles are suitable enhanced oil recovery (E.O.R) agents in water wet sand stone formations. Silica nano and carbon nano particles demonstrated same results in the wettability alteration of core plug. It was observed that the oil recovery increased by 5% when 0.05 wt. % Sio 2 nano fluid was injected into the core sample in a tertiary mode.
Chemical flooding is of increasing interest and importance due to high oil prices and the need to increase oil production. Research in nanotechnology in the petroleum industry is advancing rapidly, and an enormous progress in the application of nanotechnology in this area is to be expected. The nanotechnology has been widely used in several other industries, and the interest in the oil industry is increasing. Nanotechnology has the potential to profoundly change enhanced oil recovery and to improve mechanism of recovery, and it is chosen as an alternative method to unlock the remaining oil resources and applied as a new enhanced oil recovery method in last decade. This paper therefore focuses on the reviews of the application of nanotechnology in chemical flooding process in oil recovery and reviews the applications of nanomaterials for improving oil recovery that have been proposed to explain oil displacement by polymer flooding within oil reservoirs, and also this paper highlights the research advances of polymer in oil recovery. Nanochemical flooding is an immature method from an application point of view.
Chemical methods of enhanced oil recovery (CEOR) are applied for improving oil recovery from different kinds of oil reservoirs due to their ability for modifying some crucial parameters in porous media, such as mobility ratio (M), wettability, spreading behavior of chemical solutions on rock surface and the interfa-cial tension (IFT) between water and oil. Few decades ago, the surfactant and polymer flooding were the most common CEOR methods have been applied for producing the remained hydrocarbon after primary and secondary recovery techniques. Recently, more attention has been focused on the potential applications of the nanotechnology in enhanced oil recovery (EOR). For this purpose, many studies reported that nanoparticles (NPs) have promising roles in CEOR processes due to their ability in changing oil recovery mechanisms and unlocking the trapped oil in the reservoir pore system. This paper presents a comprehensive and up-to-date review of the latest studies about various applications of nanoparticles (NPs) within the surfactant (S), polymer (P), surfactant-polymer (SP), alkaline-surfactant-polymer (ASP) and low salinity waterflooding processes, which exhibits the way for researchers who are interested in investigating this technology. The review covers the effects of nanoparticles on wettability alteration, interfa-cial tension reduction and oil recovery improvement, and discusses the factors affecting the rock/fluid interaction behavior in porous media through the nanofluid flooding.
Application of nanotechnology for enhancing oil recovery e A review
Nanotechnology has attracted a great attention in enhancing oil recovery (EOR) due to the cost-effective and environmental friendly manner. The size of nanoparticles for EOR usually is in a range of 1e100 nm, which may slightly differ from various international organisations. Nano-particles exhibit significantly different properties compared to the same fine or bulk molecules because of much higher concentration of atoms at their surface as a result of ultra-small size. In particular, one of the most useful and fascinating properties of these particles is to creating a massive diffusion driving force due to the large surface area, especially at high temperatures. Previous studies have shown that nanoparticles can enhance oil recovery by shifting reservoir wettability towards more water-wet and reducing interfacial tension, yet this area is still open for discussion. It is worth noting that the potential of nanoparticles to reduce the oil viscosity, increase the mobility ratio, and to alter the reservoir permeability has not been investigated to date. Depending on the operational conditions of the EOR process, some nanoparticles perform more effectively than others, thus leading to different levels of enhanced recovery. In this study, we aim to provide a summary on each of the popular and available nanoparticles in the market and list their optimum operational conditions. We classified nanoparticles into the three categories of metal oxide, organic and inorganic particles in this article.
