Special Issue Information

Dear Colleagues,

The global transition toward carbon neutrality is accelerating the development of technologies across the CO2 value chain—capture, transport, utilization, and storage (CTUS). Advances in capture and injectate specification are now tightly linked to transport networks and impurity-tolerant facilities. These developments also enable subsurface deployment for utilization (notably CO2-EOR) and permanent geological storage. Recent advances in thermodynamics and phase behavior of impure CO2 mixtures, multiphase flow, geochemical and geomechanical coupling, monitoring/verification, and large-scale simulation are reshaping how CTUS systems are designed and operated. Together, these developments indicate reliable and cost-effective pathways for managing CO2 at an industrial scale, while supporting energy security.

This Special Issue of Energies aims to showcase recent advances spanning CO2 capture, transport, utilization, and storage, with an emphasis on linking surface facilities to subsurface performance. We welcome contributions that integrate experiments, modeling/simulation, field pilots or demonstrations, and data-driven methods to optimize injectate quality, transport safety, sweep/conformance, storage capacity, and long-term containment. Submissions addressing impurity management, flow assurance, well and site integrity, MMV, and risk-informed decision frameworks are particularly encouraged. Additionally, techno-economic and policy/regulatory studies that connect specification choices and network architecture to cost, safety, and storage security are also welcome.

Topics of interest for publication include, but are not limited to:

  • CO2 capture and injection specification;
  • Transport systems and hub/infrastructure design;
  • Facility engineering and operational safety;
  • Multiphase flow, phase behavior, and thermodynamics;
  • Geochemical and geomechanical processes;
  • Subsurface utilization (e.g., CO2-EOR) and geological storage practices;
  • Reservoir characterization and MMV workflows;
  • Multi-scale modeling and numerical simulation;
  • Machine learning/AI and data-driven approaches;
  • Uncertainty quantification, optimization, and decision support;
  • Well and site integrity across the project lifecycle;
  • Techno-economic and policy/regulatory studies.

Ultra-deep high-pour-point oil (waxy crude oil) reservoirs under high-temperature and high-pressure conditions are characterized by severe heterogeneity and poor displacement efficiency, with the crude oil exhibiting a pour point of approximately 47 °C. Using the XH block as a representative ultra-deep reservoir, this study systematically examines the displacement mechanisms of CO2 flooding and CO2–water-alternating-gas (WAG) flooding. This study aims to elucidate the CO2–oil interactions between CO2 and waxy crude oil, to compare oil recovery and CO2 retention under different injection modes in media with varying permeability and heterogeneity, and to provide experimental support for field-scale development. Slim tube, swelling, and long-core flooding experiments were conducted under reservoir conditions (139 °C, 57 MPa). The phase behavior between CO2 and crude oil, as well as its impact on oil volume and flow properties, was analyzed. Moreover, continuous CO2 flooding and WAG flooding were compared in low-permeability and medium–high-permeability cores, and WAG was subsequently applied to a parallel-core system to quantify the effect of interlayer heterogeneity. Results indicate that while CO2 achieves miscibility with the waxy crude at reservoir pressure, its contribution to swelling and viscosity reduction is moderate compared to light oils; thus, recovery relies primarily on miscible displacement. Compared with continuous CO2 flooding, WAG effectively delays gas breakthrough and enlarges the swept volume, leading to higher oil recovery and CO2 storage efficiency. Increasing permeability reduces flow resistance and significantly enhances the oil recovery factor. In strongly heterogeneous systems, dominant flow through high-permeability channels markedly weakens displacement in low-permeability zones, resulting in lower overall recovery and CO2 retention. These results indicate that properly designed WAG schemes can improve the development performance of heterogeneous waxy oil reservoirs while simultaneously meeting CO2 storage requirements.
