“…Therefore, the need to screen candidate chemicals that can both withstand such conditions and improve oil recovery is inevitable and an important aspect of cEOR design for these reservoirs. To overcome some of these challenges, many attempts have been made to synthesize, design, and evaluate chemical/surfactant formulations under such harsh reservoir conditions. − Others worked to introduce nanoparticles − and ionic liquids − along with surfactant flooding.…”

Chemical-enhanced oil recovery (cEOR) is a class of techniques commonly used to extract hydrocarbon fluids from reservoir rocks beyond conventional waterflooding. Surfactants are among the chemical agents employed in a cEOR process, as they aid in enhancing oil recovery by lowering the oil–water interfacial tension (IFT) and altering the rock wettability toward less oil-wet conditions. Understanding the flow characteristics and mechanisms involved during surfactant flooding helps improve the performance of injected surfactants and results in higher oil recovery. The objective of this review is to outline the recent applications of the different methods employed to understand the behavior and mechanisms involved during surfactant-enhanced oil recovery. The review begins with a general background highlighting the basic characteristics of surfactants and the main mechanisms by which they exert their influence. Recent studies conducted to investigate the oil recovery performance through different methods are then presented, including traditional coreflooding experiments, microfluidics studies, and oil recovery through sand packs. The methodology of the analysis and the interpretation of the data obtained from the different oil recovery tests, including oil recovery factor, pressure data, and relative permeability, are also described. Pore-scale analysis and imaging methods including nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI), and X-ray medical and microcomputed tomography (μCT) scanning and their applicability in assessing the recovery performance are described. Finally, a few examples of field monitoring methods for surfactant flooding are highlighted. This review provides knowledge of the different multiscale evaluation methods and their applicability during surfactant flooding.

“…Chemical and material sciences have been actively exploring the frontier of organometallic compounds, which combine metallic and nonmetallic properties with highly configurable multifunctionality. [1][2][3][4] Nowadays, multitudinous of functional organometallic compounds, such as organic precursors modified metallic oxide nanoparticles, 5 metal-containing coordination polymers, 6 organometallic surfactants, 7 and iron-rich organoclays, 8 have been designed and fabricated for the development of waste water treatment, lubricant-oil industry, heavy oil recovery, and so on. Especially, ferrocene and its considerable derivatives with typical "sandwich" molecular structure exhibit excellent chemical and thermal stability as well as unique electronic, magnetic, and catalytic properties, which have found extensive applications in the fields of biosensors, 9,10 anti-infective agents, 11 anticorrosion coating, 12 catalysts, 3,13 batteries, 14,15 smart actuators, 16 functional devices, 17 among others.…”

Tailoring of organometallics structure toward desirable properties continues to be both fascinating and challenging in the field of materials science. Herein, a novel ferrocene derivative with long straight‐chain alkane mono‐substituent is synthesized and used as multifunctional organometallic additive in the base oil. This ferrocene‐based organometallic compound (MFc) is synthesized via the Friedel‐Crafts acylation of ferrocene with myristyl chloride, followed by reduction with sodium borohydride. The chemical structure, crystallizability, surface morphology, and the thermal properties of the as‐synthesized compound are systematically characterized. As the iron‐containing standard substance, the MFc was preferable dissolve in lubricating oil with the iron element content as high as 2*105 ppm. Resultantly, the MFc/oil solutions exhibited excellent stability even after high‐speed centrifugal treatment, long‐term storage up to 3 months, and ultra‐low temperature treatment at −40°C for 24 h. Moreover, the MFc as a functional lubricant additive could reduce the average wear scar diameter, wear volume, and coefficient of friction with 40%, 73%, and 18%, respectively, as compared to the corresponding pure base oil. This synthetic strategy provides a novel perspective for the design of functional organometallics, and the as‐synthesized novel ferrocene derivative may find a wide range of advanced potential applications in analytical chemistry, tribology, and interfacial science.

“…Although many studies are being conducted, on the idea of using nanomaterials for enhancing oil recovery (EOR) there are still several obstacles that prevent its widespread implementation at the field scale (Kazemzadeh et al 2019 ; Afolabi 2018 ; Davoodi et al 2022 ). The difficulty in determining the number of nanoparticles to be used, the lack of available data for predictive modeling, the high production cost of nanoparticles combined with the huge capital investment in extraction of hydrocarbons, the lack of clear mechanisms with supported solid evidence, formation heterogeneity, the difficulty in attaining stability of nanoparticles are some of the challenges faced in the oil and gas industry that hinder in the full field application of nano-EOR (nano-enhanced oil recovery) methods, a rise in rheological characteristics and expense as a result of pipe obstruction, and sometimes results in pipe breakage and crude oil leaks, posing significant environmental difficulties (Leng et al 2019 ; Satyarthi et al 2011 ; Alsabagh et al 2016 ; Luo et al 2020 ; Zehua and Xiutai 2015 ; Huaping et al 2006 ; Abdelhamid et al 2021 ).

In this work, a beneficial approach for efficient depolymerization of lignin and controllable product distribution is provided. Lignin, an abundant aromatic biopolymer, has the potential to produce various biofuels and chemical adsorption agents and is expected to benefit the future circular economy. Microwave-ultrasonic (MW/US) assisted efficient depolymerization of lignin affords some aromatic materials used in manufacturing the starting material to be investigated. Some nano organometallic surfactants (NOMS) based on Ni2+, Cu2+, Co2+, Fe3+, and Mn2+ besides 2-hydroxynaphth-sulphanilamide are synthesized to enhance oil recovery (EOR). In this work, the assessment of the NOMS’s efficiency was improving the heavy oil recovery via the study of the dynamic interfacial tension (IFT), contact angle, and chemical flooding scenarios. The NOMS-Ni2+ exhibited the maximum reduction of viscosity and yield values. Dropping the viscosity to 819.9, 659.89, and 499.9 Pa s from blank crude oil viscosity of 9978.8, 8005.6, and 5008.6 Pa s respectively at temperatures of 40, 60, and 80 °C was investigated. The reduction of τB values was obtained also by OMS-Ni2+. The minimum IFT was recorded against the Ni2+ derivatives (0.1 × 10–1 mN m−1). The complete wettability alteration was achieved with the NOMS-Ni2+ surfactant (ɵ $$\cong 6.01).$$ ≅ 6.01 ) . The flooding test has been steered in 3 sets using the sand-packed model as a porous media at surfactant concentrations (1, 1.5, 2 and 2.5%) at 50 °C and 499 psi as injection pressure. The best value (ORs) formed for NOMS-Ni2+ were 62, 81, 85.2, and 89% respectively as compared with other NOMS-M2+ at the same concentrations. The mechanism of alternating wettability was described in the text. The rheology of the used heavy crude oil was investigated under temperatures of 40, 60, and 80 °C. Graphical Abstract
