In this study, novel amphiphilic polymer emulsifiers for avermectin (Avm) were synthesized facilely via the hydrolysis of ethylene-maleic anhydride copolymer (EMA) with different agents, and their structures were confirmed by various techniques. Then, water-based Avm-nanoemulsions were fabricated with the emulsifiers via phase inversion emulsification process, and superior emulsifier was selected via the emulsification effects. Using the superior emulsifier, an optimal Avm-nanoemulsion (defined as Avm@HEMA) with satisfying particle size of 156.8 ± 4.9 nm, encapsulation efficiency (EE) of 69.72 ± 4.01% and drug loading capacity (DLC) of 54.93 ± 1.12% was constructed based on response surface methodology (RSM). Owing to the emulsifier, the Avm@HEMA showed a series of advantages, including high stability, ultraviolet resistance, low surface tension, good spreading and high affinity to different leaves. Additionally, compared to pure Avm and Avm-emulsifiable concentrate (Avm-EC), Avm@HEMA displayed a controlled releasing feature. The encapsulated Avm was released quite slowly at normal conditions (pH 7.0, 25 °C or 15 °C) but could be released at an accelerated rate in weak acid (pH 5.5) or weak alkali (pH 8.5) media or at high temperature (40 °C). The drug releasing profiles of Avm@HEMA fit the Korsmeyer–Peppas model quite well at pH 7.0 and 25 °C (controlled by Fickian diffusion) and at pH 7.0 and 10 °C (controlled by non-Fickian diffusion), while it fits the logistic model under other conditions (pH 5.5 and 25 °C, pH 8.5 and 25 °C, pH 7.0 and 40 °C).

As the oil and gas industry continues to evolve, the utilization of advanced materials becomes crucial for maximizing efficiency and productivity. Nanoemulsions (NEs) have emerged as a promising solution for various downhole applications. Their unique properties, enhanced stability, and improved performance have led to applications in enhanced oil recovery, drilling fluids, fracturing fluids, and produced water treatment. However, while NEs offer significant advantages, production costs, stability during transportation and storage, as well as scale-up challenges must be carefully considered. This chapter aims to provide an overview of NEs for oil and gas applications, discussing the current benchmark, potential implementation, properties, and various applications. Furthermore, it will provide recommendations and insights on how to effectively implement NEs in the field. It is important to recognize that the ongoing research and development efforts hold the potential to further revolutionize the oil and gas applications and contribute to a more sustainable processes and operations.

“…under diverse reservoir conditions is one of the challenges involved in scaling up NF-based EOR systems. 184 The efficiency of the NPs can be decreased by agglomeration or sedimentation. To ensure that NFs perform as expected in the field, it is vital to maximize their stability and dispersion during injection and transit.…”

Chemical-enhanced oil recovery (chemical-EOR) is a unique strategy that employs chemical agents with special properties for enhancing crude oil recovery from matured reservoirs. However, chemical-EOR techniques face challenges, such as chemical deterioration under reservoir conditions and high cost. Nanotechnology, through the use of nanoparticles (NPs), and nanofluids (NFs), has shown promise in enhanced oil recovery by improving the thermal stability of chemicals under harsh conditions, reducing interfacial tension, and altering the wettability. Despite these potential advantages, a comprehensive review that addresses the screening requirements, comparative study of different NFs, and assessment of their economic viability is lacking. This review delves into factors impeding the performance of NFs as EOR agents, scrutinizes screening criteria, assesses their compatibility with other EOR techniques, examines real-world field applications, economic viability, and comparative study of chemical-EOR and NPs-assisted chemical-EOR, and elucidates existing opportunities and challenges. The findings suggest that NPs have the potential to serve as partial substitutes for chemicals due to their ability to control fine migration, reduce interfacial tension, alter wettability, and enhance emulsion stability. This highlights significant technical and commercial opportunities for nanotechnology in the field of EOR. The review aims to provide a comprehensive understanding of how nanotechnology can be applied in the chemical-EOR domain, establishing a foundation for research and development in this area
