Special Issue Information

Dear Colleagues,

The urgency of mitigating anthropogenic carbon emissions has accelerated the development of carbon capture and storage (CCS) as a key pathway toward net-zero energy systems. CCS integrates multidisciplinary challenges across capture efficiency, transport, and long-term subsurface storage. Recent advancements in experimental geomechanics, rock-fluid interactions, reactive transport modeling, and in situ monitoring have significantly enhanced our understanding of CO2 behavior in geologic formations, including saline aquifers, depleted hydrocarbon reservoirs, and caprock formations. However, questions remain about long-term sealing integrity, fracture responses, and the coupling of thermal, hydraulic, mechanical, and chemical (THMC) processes under in situ conditions.

This Special Issue aims to present cutting-edge research focused on advanced technologies that support the secure and efficient deployment of CCS. We invite original research and reviews that encompass experimental studies, modeling approaches, and monitoring techniques relevant to CCS.

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

  • Coupled THMC processes in carbon storage reservoirs;
  • Caprock integrity and fracture self-sealing mechanisms;
  • Stress-path dependent injectivity and geomechanical evolution;
  • CO₂-brine-rock interaction and mineral trapping;
  • Pore-scale and continuum-scale multiphase flow modeling;
  • Fiber-optic and real-time monitoring techniques for injection and containment;
  • Long-term risk assessment and leakage prediction methods;
  • Numerical upscaling from microfluidics to field-scale simulations;
  • Integration of CCS with hydrogen or geothermal co-injection systems.

We look forward to your contributions to advance the science and technology for CCS.

The aim of this work was to investigate the evolution of the mechanical integrity of the selected offshore oil reservoir during its life cycle. The geomechanical stability of the reservoir formation, including the caprock and base rock, was investigated from the exploitation phase through waterflooding production to the final phase of enhanced oil recovery (EOR) with CO2 injection. In this study, non-isothermal flow simulations were performed during the process of cold water and CO2 injection into the oil reservoir as part of the secondary EOR method. The analysis of in situ stress was performed to improve quality of the geomechanical model. The continuous changes in elastic and thermal properties were taken into account. The stress–strain tensor was calculated to efficiently describe and analyze the geomechanical phenomena occurring in the reservoir as well as in the caprock and base rock. The integrity of the reservoir formation was then analyzed in detail with regard to potential reactivation or failure associated with plastic deformation. The consideration of poroelastic and thermoelastic effects made it possible to verify the development method of the selected oil reservoir with regard to water and CO2 injection. The numerical method that was applied to describe the evolution of an offshore oil reservoir in the context of evaluating the geomechanical state has demonstrated its usefulness and effectiveness. Thermally induced stresses have been found to play a dominant role over poroelastic stresses in securing the geomechanical stability of the reservoir and the caprock during oil recovery enhanced by water and CO2 injection. It was found that the injection of cold water or CO2 in a supercritical state mostly affected horizontal stress components, and the change in vertical stress was negligible. The transition from the initial strike-slip regime to the normal faulting due to formation cooling was closely related to the observed failure zones in hybrid and tensile modes. It has been estimated that changes in the geomechanical state of the oil reservoir can increase the formation permeability by sixteen times (fracture reactivation) to as much as thirty-five times (tensile failure). Despite these events, the integrity of the overburden was maintained in the simulations, demonstrating the safety of enhanced oil recovery with CO2 injection (EOR-CO2) in the selected offshore oil reservoir.

With increasing attention paid to the development of natural gas hydrates, various mining methods have been studied. CO2-CH4 hydrate replacement has become one of the key research topics in the field of natural gas hydrate mining because it can overcome the disadvantage of traditional mining methods that easily lead to reservoir collapse and realize CO2 sequestration while extracting CH4. However, complex heat and mass transfer, as well as fluid migration, are involved in CO2-CH4 hydrate in situ replacement, and this method has the drawbacks of slower reaction rates and a lower replacement efficiency compared to traditional methods. Therefore, a substantial amount of experimental and simulation research is still needed to advance this method. This paper reviews the current research on CH4 recovery from CH4 hydrate by CO2 replacement. The main CO2-CH4 hydrate replacement mechanisms are summarized according to whether the hydrate cage structure is disrupted. Numerical simulation studies based on the above replacement mechanisms are introduced and compared in detail. The effects of various replacement methods, such as soaking replacement and dynamic replacement, as well as factors including the presence of initial water, reservoir permeability, temperature, and pressure on the replacement reaction, are summarized. Additionally, existing pore-scale replacement studies are reviewed, highlighting the necessity of pore-scale research on CO2-CH4 hydrate replacement reactions, pointing out the shortcomings of current pore-scale studies, and proposing suggestions for future research directions. This work provides a reference for the development of the CO2-CH4 hydrate replacement method and the realization of its industrial applications. Full article
