“…Microfluidics was initially widely applied in the fields of life sciences and chemical engineering . In recent years, it has also gradually developed in the oil and gas industry, − particularly demonstrating unprecedented advantages in the phase behavior, dissolution, diffusion, and other aspects of oil and gas. − With the booming development of unconventional oil and gas production, MMP in nanoscale-confined spaces has received widespread attention. Therefore, a rapid and efficient method has also been increasingly used to determine the MMP. , For example, Nguyen et al determined the MMP of a mixture of pentane and hexadecane at the micrometer scale, with a difference in results of less than 0.5 MPa.…”

The large-scale development of onshore shale oil is not only an inevitable choice under the current oil and gas resource endowment in China but also a vivid practice to ensure national energy security. The CO 2 Huff-n-Puff method, as one of the main ways to enhance the recovery factor of shale oil, has broad application prospects. In view of the complex interaction mechanism of the CO 2 -hydrocarbon system in the nanospace, which is still poorly understood and lacks experimental means, this paper designs two types of terminal-closed single tubes and porous medium tubes in a nanochip. This design, different from the open-ended single tube, can effectively eliminate the influence of convection and more realistically simulate the fluid mobilization process in the dead-end pores of shale. Based on the nanofluidics experimental, we utilized fluorescence and bright-field imaging to further clarify the gas−liquid miscible process. Additionally, we determined the minimum miscibility pressure (MMP) of CO 2 with seven single-component alkanes and multicomponent mixtures at a high temperature of 70 °C and a scale of 30 nm. Notably, we first discovered that the MMP of a multicomponent mixture composed of C 6 , C 10 , and C 16 in a 10:44:16 molar ratio at a size of 30 nm was 4.37% lower than that in the bulk, providing evidence for the presence of a confinement effect. In addition, we find that the nanofluidics not only has extremely low time cost and minimal sample usage but also has good accuracy (maximum error not exceeding 5%). This effective method, combined with a large amount of MMP values for CO 2 and elemental alkanes as well as multicomponent mixtures at reservoir temperatures, may provide theoretical support for CO 2 -enhanced oil recovery.

“…The channel characteristic size of the microreactor is usually in the order of tens to hundreds of microns, greatly increasing the specific interfacial area for mass transfer. Owing to this benefit, numerous studies have been conducted on the microchannel based CO2 chemical absorption over the past decades (Zanfir et al, 2005;TeGrotenhuis et al, 2000), the latest advances are summarized in recent review papers (Cheng et al, 2023;Pasha et al, 2022). However, some limitations still exist, mainly due to the laminar regime of two-phase flow at small Reynolds numbers (Re) of liquid and gas in the microchannel.…”

The need to mitigate carbon dioxide has motivated an influx of interest in innovative technologies, and microfluidic systems have emerged as a promising forefront in this endeavor. This short review analyzes CO2 reduction within microfluidic platforms, thoroughly investigating existing methodologies, challenges, and novel perspectives. This work commences with a detailed exposition of the fundamental principles governing microfluidic electrolyzers, elucidating the interaction of microchannels and electrodes. We show the electrochemical reactions supporting CO2 reduction, detailing the processes at the cathode. The use of microfluidic systems encompasses precise control over reaction conditions, efficient mass transport, reduced energy consumption, high throughput screening capabilities, integration with analytical tools, and portability. Catalyst selection for optimal CO2 reduction products, technical complexities, integration of renewable energy sources, and cost‐effectiveness are notable challenges on the horizon. A perspective on potential pathways to resolution is delineated, with each impediment succinctly but insightfully addressed. Moreover, this review extends beyond a looking‐back analysis, propounding innovative perspectives. It posits the concept of microfluidic fuel cells directly fueled by CO2. This work seeks to inspire new researchers and innovation in the field by comparing the present state‐of‐the‐art with prospective avenues of exploration
