Special Issue Information

Dear Colleagues,

It is difficult to envision a low‑carbon future without effective carbon capture, utilization and storage (CCUS) technologies. These approaches have been rapidly expanding, not only in traditional industrial and energy sectors but also in newer domains such as unconventional resource recovery, enhanced oil recovery (EOR), advanced drilling and completion techniques, and integrated CO2 transportation and sequestration systems. The increasing deployment of CCUS has driven significant progress in understanding CO2’s interactions with subsurface rocks and fluids, CO2 migration pathways and trapping mechanisms, and innovations in the utilization of CO2 as a working fluid in drilling, completion, and production operations.

On the other hand, the growing demand for safe, efficient, and economically viable CCUS solutions has accelerated research into multiphase flow modeling, reactive transport processes, geochemical and geomechanical coupling, and large‑scale monitoring of storage integrity. These advances are critical for ensuring the secure geological sequestration of CO2, minimizing environmental risks, and optimizing the integration of CO2‑based technologies into energy production and industrial supply chains.

This Special Issue, New Advances in Carbon Capture, Utilization and Storage (CCUS), aims to highlight the latest developments in research on the mechanisms, modeling, applications, monitoring, and safety protocols across the full CCUS value chain.

Topics of interest include, but are not limited to, the following:

  • CO2–rock–fluid interaction mechanisms in various geological formations;
  • Migration and trapping processes in saline aquifers, depleted reservoirs, and unconventional formations;
  • CO2 applications in drilling engineering for wellbore stability, cooling, and fluid management;
  • Use of CO2 in completion operations for enhanced zonal isolation and stimulation;
  • CO2‑EOR processes and integrated storage strategies;
  • CO2 utilization for unconventional resource recovery (tight oil, shale gas, coalbed methane);
  • Principles and innovations in CO2 gathering, transportation, and injection systems;
  • Safety and integrity monitoring for long‑term geological sequestration;
  • Coupled reactive transport and geomechanical modeling approaches;
  • Novel diagnostic and sensing technologies for CCUS operations.

Excessive CO2 emissions cause global warming, while CO2 interaction with crude oil can enhance oil recovery (EOR). To capture and reuse CO2, nano-SiO2 was cationically modified to synthesize nanoparticles (SCR2). The structure and performance of SCR2 were characterized by FT-IR, DLS, and TEM, confirming its excellent CO2 adsorption capacity and surface activity. Compared with unmodified nano-silica, SCR2 increased CO2 adsorption capacity by 254.3% and reduced the core surface contact angle from 112.1° to 24.5°. Core flooding experiments showed that in low-permeability reservoirs, SCR2 achieved a plugging rate of 87.5%, an enhanced oil recovery of 24.8%, and an ultimate oil recovery of 74.8% (23.8% higher than unmodified nano-silica). Mechanistically, SCR2 plugs gas channeling pathways via its inherent nanoparticle properties and adsorption of dissolved CO2 in the aqueous phase while improving rock surface wettability, thereby enhancing sweep efficiency and total oil recovery during CO2 flooding. This study provides a promising approach for EOR and CO2 resource utilization in low-permeability reservoirs. Full article

CO2 pipeline transportation is a core link in the CCUS (Carbon Capture, Utilization, and Storage Technology) industry. Ensuring the flow safety of CO2 pipelines under transient conditions is currently a key and challenging issue in industry research. This paper focuses on the phase migration and safety control during the shutdown process of supercritical carbon dioxide pipelines. Taking a supercritical carbon dioxide transportation pipeline in Xinjiang Oilfield, China, as the research object, a hydro-thermal coupling model of the pipeline is established to simulate the pipeline and elucidate the coordinated variation patterns of temperature, pressure, density, and phase state. It was found that there were significant differences in the migration paths of the CO2 phase at different positions. The accuracy of the simulation results was verified through the self-built high-pressure visual reactor experimental system, and the influences of the initial temperature, initial pressure, and ambient temperature before pipeline shutdown on the slope of the phase migration path were explored. The phase migration line slope prediction model was established by using the least squares method and ridge regression method, the process boundary ranges and allowable shutdown time ranges for pipeline safety shutdowns in both summer and winter were further established. The research results show that when the pipeline operates under the low-pressure and high-temperature boundary, the CO2 in the pipeline vaporizes earlier from the starting point after the pipeline is shut down, and the safe shutdown time of the pipeline is shorter. There is a clear safety operation window in summer, while vaporization risks are widespread in winter. The phase migration path prediction formula and the safety zone division method proposed in this paper provide a theoretical basis and engineering guidance for the safe shutdown control of supercritical carbon dioxide pipelines, which can help reduce operational risks and lower maintenance costs.
