Abstract

Chemiresistive sensing lies in its ability to provide fast, accurate, and reliable detection of various gases in a cost‐effective and non‐invasive manner. In this context, graphene‐functionalized metal oxides play crucial role in hydrogen gas sensing. However, a cost‐effective, defect‐free, and large production schemes of graphene‐based sensors are required for industrial applications. This review focuses on graphene‐functionalized metal oxide nanostructures designed for gaseous molecules detection, mainly hydrogen gas sensing applications. For the convenience of the reader and to understand the role of graphene‐metal oxide hybrids (GMOH) in gas sensing activities, a brief overview of the properties and synthesis routes of graphene and GMOH have been reported in this paper. Metal oxides play an essential role in the GMOH construct for hydrogen gas sensing. Therefore, various metal oxides‐decorated GMOH constructs are detailed in this review as gas sensing platforms, particularly for hydrogen detection. Finally, specific directions for future research works and challenges ahead in designing highly selective and sensitive hydrogen gas sensors have been highlighted. As illustrated in this review, understanding of the metal oxides‐decorated GMOH constructs is expected to guide ones in developing emerging hybrid nanomaterials that are suitable for hydrogen gas sensing applications.

Abstract

AbstractUnderstanding polymer retention is a critical aspect in the field of chemical-enhanced oil recovery (cEOR). This article presents a comprehensive review of polymer retention in reservoir rocks, focusing on the underlying mechanisms, measurement techniques, and the factors influencing this phenomenon. Three main (proposed) mechanisms that contribute to polymer retention are discussed in detail. Polymer adsorption, hydrodynamic retention, and mechanical entrapment are identified as key factors affecting the overall retention of polymers during flow through porous media. Also, herein, we explore the details of these mechanisms, explaining how polymer characteristics and rock surface properties influence the degree of retention. Furthermore, we analyze the influencing factors that affect polymer retention. The rock surface properties, such as surface charge and wettability, play a vital role in determining the interaction between polymers and rocks. The interplay of these factors provides valuable insights into understanding and controlling polymer retention in cEOR applications. This review paper put in a nutshell a comprehensive understanding of the mechanisms, measurement techniques, and influencing factors involved. [ABSTRACT FROM AUTHOR]

35. A Review on Wettability Alteration in Carbonate Rocks: Wettability Modifiers

Author

Deng, Xiao, Kamal, Muhammad Shahzad, Patil, Shirish, Hussain, Syed Muhammad Shakil, and Zhou, Xianmin

Abstract

More than half of the global oil reserves are in carbonate reservoirs. Carbonate rocks, however, in most cases tend to be mixed-wet or oil-wet. Wettability alteration of carbonate reservoir rock has been proven to increase oil recovery significantly. Several chemicals have shown their effect on wettability; however, selection of an appropriate wettability modifier should be made on the basis of the underlying mechanisms and their behavior at reservoir conditions. This review discusses techniques that can help in assessing wettability alteration or reflect on the underlying mechanism and describes several categories of wettability modifiers focusing on their structure–property relationship and factors affecting their performance at reservoir conditions. Surfactants, nanoparticles, salts, and alkalis are four major categories of wettability modifiers that are discussed in this review. Among surfactants, gemini surfactants have great potential and could be a major focus of future research in this area. Nanoparticles are relatively novel materials for wettability alteration with the capability to reduce contact angle significantly at low cost. This review also identifies the current and future challenges related to the performance of various wettability modifiers at high-temperature and high-salinity conditions.

36. Static adsorption of a novel cationic gemini surfactant: A mineralogical study

Author

Abstract

Surfactants are deemed as an advantageous chemical in enhanced oil recovery (EOR) because of their potential of lowering the interfacial tension and modifying the wettability. However, the surfactant loss by adsorption on the rock surface is one of the major shortcomings of surfactant-based flooding techniques. The static adsorption of an in-house synthesized cationic gemini surfactant (GS12) is investigated as a function of mineral type, salinity, and concentration. Both clay and non-clay minerals have been examined. Surfactant adsorption was increased continuously by the increase of concentration till 1000 ppm and then an adsorption plateau was observed in all minerals except montmorillonite and kaolinite. It was found that clay minerals may cause more detrimental effects as compared to silicate minerals and carbonate minerals showed the least adsorption. The maximum amount of surfactant adsorbed on the mineral surface was in the order of montmorillonite > kaolinite > illite > K-feldspar > quartz > dolomite > calcite. Lower adsorption of GS12 was detected because of the presence of multivalent ions (Ca2+and Mg2+). Methylene blue (MB) has been revealed as a novel adsorption inhibitor for cationic GS12 on various minerals. MB adsorbs on the negative binding sites of both clay and non-clay minerals. Therefore, an electrostatic repulsion takes place between the cationic dye (MB) and cationic GS12, leading to the reduction of GS12 adsorption on the mineral surface. Only the addition of 100 ppm of MB in the surfactant solution at the highest concentration (1500 ppm) reduced GS12 adsorption on quartz surface to 0.67 mg/g-rock. This study will help in designing the chemical EOR process using GS12 on carbonate formation containing silica and clay minerals as impurities.
