“…Imaging techniques can describe quantitative information about pore space, such as X-ray computed tomography (X-CT), ,− which can quantify porosity and the pore size distribution, but X-CT can only scan small core samples. Scanning electron microscopy (SEM) and atomic force microscopy (AFM) can reveal the microscopic morphological characteristics of rocks, including the distribution of pores, mineral content, and surface morphology of rocks. Focused ion beam scanning electron microscopy (FIB-SEM) enables the imaging and quantification of mineral and organic matter content, pore morphology, and topological features.…”

Carbon capture, utilization, and storage (CCUS) technology has shown rapid development in recent years as an important technology to reduce carbon emissions, of which CO 2 geological storage is an important part. Due to the complexity of CO 2 geological storage, especially the long period of mineralization storage, intensive studies have been conducted to reveal the mechanism of mineralization storage. This review presents a comprehensive understanding of the mineralization storage mechanism and its application prospects by introducing various experimental tools to deepen the characterization of pore-scale and core-scale changes during mineralization storage and promote the application of mineralization storage in large-scale carbon storage studies through geochemical simulations and field-scale demonstrations. This review summarizes representative multiscale studies of mineralization storage in typical reservoirs. The main findings are as follows: (1) For CO 2 −water−rock reactions, in addition to the influence of the inherent inhomogeneity of reservoir rocks (properties of mineral components, etc.), the environmental conditions of the reservoir (pH, temperature, pressure, etc.) have a strong influence on the dissolution and precipitation processes during mineralized storage. (2) The mineralization sealing process is accompanied by a complex evolution of pore-permeability properties. The mineral dissolution stage causes an increase in pore space and significantly improves the fluid injection capacity, while the mineral reprecipitation process causes problems such as pore throat blockage, which often affects the safety of sealing. (3) The modeling approach, combined with laboratory work, allows for large-scale and time-scale predictions. In addition, the current implementation of successful demonstration projects is summarized to promote the use of CO 2 storage in field engineering applications. Finally, directions for future development and research are proposed.

“…Furthermore, the 2D and 3D AFM figures show that the rock surface roughness seems to be higher at the same position after being treated by the electric field. Here, root mean square roughness ( R q ) and average roughness ( R a ) were employed to quantitively analyze the surface roughness of the rock. , Various area dimensions were chosen to further ascertain the reliability of the surface roughness of the sample (Supporting Information). The surface roughness of the sample before and after electric field exposure is shown in Figure .…”

Insights into the Relationship between Wettability and Surface Roughness in Tight Reservoirs from a Pore-Scale View: Effect of Electric Field

et al. 2023

The surface roughness of reservoirs detected by AFM is typically employed to predict the wettability of a sandstone reservoir. However, the resulting predictive relationship represents the surface roughness in only the intragranular region due to the limitations of the AFM probe. For a long time, the detection of surface roughness in the intergranular region, especially that of a sandstone reservoir treated with an external stimulus, has not attracted much attention. This paper proposed an in situ AFM and SEM method for measuring the surface roughness in the different regions of tight sandstone treated with an electric field, further revealing the wettability alteration from a pore-scale perspective. The results show that the electric field exposure increases the surface roughness in the intragranular and intergranular regions, synthetically strengthening the water-wetness of tight sandstone. Notably, pore parameter changes in the intragranular region differ from those in the intergranular region. Pore length decreases in the intragranular region and also in the intergranular region, and pore number remains unchanged in the intragranular region but decreases in the intergranular region. Moreover, pore depth increases in the intragranular region but decreases in the intergranular region. The movement of clay minerals induced by the electric field accounts for the difference in the roughness alteration in the two regions. This paper sheds light on new ways to approach surface roughness measurement that can greatly improve the understanding of the relationship between surface roughness and wettability of reservoirs. In addition, the work presented in this paper may be vital in determining the surface roughness of homogeneous materials treated by external stimulation.

“…Proposed in [201], the tapping-mode AFM (cf. Figure 10(a)) gauges the tip-sample interaction force by optical sensors (or strain gauges) with reduced lateral force and therefore less tip/sample degradation, making itself a useful tool not only in biomaterial and soft medium engineering [202] but also in quantification of hard geological material properties [203,204].…”

Spurred by the invention of the tapping-mode atomic force microscopy three decades ago, various micromechanical structures and systems that utilize parts with mechanical impact have been proposed and developed since then. While sharing most of the dynamical characteristics with macroscopic vibro-impact systems and benefiting from extensive theories developed, microscale counterparts possess higher percentage of surface force, higher resonance frequency and Q, and more prominent material and structural nonlinearities, all of which lead to unique features and in turn useful applications not seen in macroscopic vibro-impact systems. This paper will first present the basics of vibro-impact systems and techniques used for analyzing their nonlinear behaviors and then review the contact force modeling with an emphasis in microscale and numerical analysis tools. Finally, various applications of microscale vibro-impact systems will be reviewed and discussed. This review aims to provide a comprehensive picture of MEMS vibro-impact systems and inspire more innovative applications that take full advantage of the beauty of nonlinear vibro-impact dynamics in the microscale.
