“…The smallest pore and throat size of the model can reach nanoscale using etching techniques (e.g., interference lithography, electron beam lithography, polymer nanochannels). [100][101][102][103] The fluid flow during CO 2 flooding can be obviously monitored by pore-scale visualization techniques. However, there are still challenges, including the pressure limitation of the experimental model and the difference between the constructed model and reservoir.…”

Rapidly rising emissions of greenhouse gases into the atmosphere lead to the greenhouse effect and accelerate the exacerbation of the global climate. [1] Greenhouse gases include carbon dioxide (CO 2), ozone (O 3), nitric oxide (N 2 O), methane (CH 4), hydrogen fluoride, the chlorine carbide class (CFCs, HFCs, HCFCs), and perfluorinated carbide (PFCs) and sulfur hexafluoride (SF 6). The concentration of CO 2 is the highest in the atmosphere among greenhouse gases, and it significantly dominates global warming. [2] The process of the greenhouse effect and the impact of greenhouse gases on global warming are shown in Figure 1. Carbon is one of the most important elements of earth's structure and living things. It widely exists in the biosphere, lithosphere, hydrosphere, and atmosphere and circulates continuously with the movement of the Earth. CO 2 plays an important role in the cycle. Green plants absorb CO 2 from the atmosphere, and CO 2 is converted into organic matter and oxygen is also released through photosynthesis with the participation of water, as shown in Figure 2. [3,4] Before the industrial revolution, the carbon cycle has been kept in balance for millions of years. After the industrial revolution, human beings began to utilize fossil fuels to obtain energy. The balance of nature is thus destroyed, leading to climate anomalies (e.g., global warming) due to the increased concentration of CO 2 caused by the burning of fossil fuels and other industrial activities. Therefore, reducing emissions of CO 2 and other greenhouse gases is essential for protecting the natural environment. [5,6] At present, carbon emissions can be reduced by decreasing energy consumption, improving energy utilization efficiency, replacing fossil fuels with clean energy (e.g., solar energy, wind energy, geothermal energy, and hydrogen energy), and carbon capture and storage (CCS). However, it is still hard for most of the clean energy to completely replace fossil fuels in the near future because of safety, technology availability, and economical efficiency. [7] CCS is an important technological means to reduce carbon emission. [8,9] However, CCS requires high costs and may cause leakage of carbon because the captured carbon is usually sequestrated in saline aquifers, coal seams, depleted reservoirs, etc. [10-12] Therefore, carbon capture, utilization and storage (CCUS) has been acknowledged as a promising technology to achieve efficient reduction of carbon and also generate economic benefits, which is more practical and economical. [13] CO 2 is an important material for industry and has been applied in many fields, as shown in Figure 3. [14,15] In the food industry, CO 2 is used in the production of carbonized beverages, food preservation, and industrial processing as a refrigerant and protective gas. It can also be applied to synthesize chemicals, drugs, polymers, such as degradable plastics, etc. High-purity

“…An image processing approach, ImageJ, is introduced to visualize and quantify the dynamic dissolution process in micromodel. Another study published by Journal of Petroleum Science and Engineering, focusing on the pore-scale swelling behavior of clays in pore channel, has concluded that the effective porosity in micromodel during low salinity water (LSW) flooding effectively can be quantified through comprehensive image processing, MATLAB Image Processing Toolbox (Sharifipour et al 2019). Thus, this research will explore on severity of damage thickness in 2D micromodel executed from extensive image analysis to fill the research gaps, as part of novelty.…”

Micromodel can provide valuable information to improve understanding of pore-scale transport phenomenon and can also be utilized to simulate the transport process at pore scale. This research aims to propose settlement option for quantification of suspended solids in micromodel. The micromodel is used to mimic the formation damage which occurs in reservoir formation that could simultaneously affect enhanced oil recovery. This is done by utilizing visual image interpretation through image analysis on micromodel chip. Following the quantification of suspended solids, the micromodel was injected with brine that eventually forms agglomeration. Images are taken from NIS-Element AR microscope automatically in RGB color profile and then made into grayscale and finally into binary modes. Since the micromodel is simulated in 2D form structure, the quantification method complemented with image analysis is focusing on the quantified area, µm2 region of interest categorized into 3 main groups of area B05, M45 and T50, respectively. This research will explore on segmentation and thresholding processes of the visual data acquired from micromodel experiment. An image-based computational algorithm is programmed in MATLAB Image Processing Toolbox and ImageJ; hence, suspended solids in porous media could be quantified from the visual image executed in micromodel.

“…Finally, heat treatment for thermal fusion process in an oven would be necessary to ensure the plates are fully attached and sealed [12]. Sharifipour et al [13] studied the effect of clay swelling on the oil recovery factor in a porous medium using micromodels, where the device was made through this process. Furthermore, a laser-etched rock on-chip was also used to resemble the pore space and fracture geometries [14].…”

“…They used this microfluidic model to analyze the effects of brine injection on clay detachments. In a separate study, micromodels were coated with high swelling clay minerals to model the behavior of sandstones that contain swelling clays [13]. Other researchers later used a layer-by-layer self-assembly technique to coat the surface of channels in microfluidic chips with geomaterials [26].…”

Visualizing fluid flow in porous media can provide a better understanding of transport phenomena at the pore scale. In this regard, transparent micromodels are suitable tools to investigate fluid flow in porous media. However, using glass as the primary material makes them inappropriate for predicting the natural behavior of rocks. Moreover, constructing these micromodels is time-consuming via conventional methods. Thus, an alternative approach can be to employ 3D printing technology to fabricate representative porous media. This study investigates fluid flow processes through a transparent microfluidic device based on a complex porous geometry (natural rock) using digital-light processing printing technology. Unlike previous studies, this one has focused on manufacturing repeatability. This micromodel, like a custom-built transparent cell, is capable of modeling single and multiphase transport phenomena. First, the tomographic data of a carbonate rock sample is segmented and 3D printed by a digital-light processing printer. Two miscible and immiscible tracer injection experiments are performed on the printed microfluidic media, while the experiments are verified with the same boundary conditions using a CFD simulator. The comparison of the results is based on Structural Similarity Index Measure (SSIM), where in both miscible and immiscible experiments, more than 80% SSIM is achieved. This confirms the reliability of printing methodology for manufacturing reusable microfluidic models as a promising and reliable tool for visual investigation of fluid flow in porous media. Ultimately, this study presents a novel comprehensive framework for manufacturing 2.5D realistic microfluidic devices (micromodels) from pore-scale rock images that are validated through CFD simulations.
