Summary: The study investigates the feasibility of storing CO2 inside hydrate stability zone (HSZ) through reservoir pressure management via water producers and CO2 injectors. Results show that by controlling reservoir pressure, CO2 can be stored in HSZ with the formation of CO2 hydrate delaying CO2 breakthrough and limiting gas leakage. The research highlights the potential of storing CO2 in aquifers with a HSZ, with implications for CO2 geological storage.

Summary: Underwater reservoirs in the South Yellow Sea Basin (SYSB), China, provide favorable geological conditions for carbon dioxide (CO2) storage, as determined by the USDOE calculation method and a formation volume model. The Cenozoic saline aquifers in the SYSB have a significant storage capacity of CO2, ranging from 39.59 Gt to 426.94 Gt, which can meet the carbon sequestration needs of Shandong and Jiangsu Provinces for approximately 89 years.

Summary: A four-scale and three-level CO2 storage potential evaluation method for saline aquifers in a petroliferous basin in China is proposed, considering geological, engineering, and economic factors. The method evaluates theoretical storage capacity, engineering storage capacity, and economic storage capacity, considering factors such as trapping mechanisms, injectivity, storage security pressure, well number, and carbon pricing yield. Application of this method in the Gaoyou sag of the Subei Basin reveals the proportion of different trapping mechanisms and highlights the significant difference between theoretical, engineering, and economic storage capacity.

Summary: This study investigates the effect of CO2 injection pressure on gas migration characteristics and coalbed methane (CBM) extraction. Experimental tests were conducted using a CH4 to CO2 replacement platform under different CO2 injection pressures. The results indicate that gas migration rate increases with higher injection pressure, and CH4 desorption rate and coal seam permeability display different stages of decline and stability. Higher injection pressure leads to increased CH4 desorption volume and CO(2) sequestration volume, and improved CH4 extraction efficiency. These findings are of great importance for optimizing CO2 injection pressure and enhancing CBM extraction.

Summary: Efficient injection of carbon dioxide and its potential effects on injection costs require an understanding of the interactions between rock and fluid during the CO2 storage process. This study used core flooding experiments to investigate the changes in porous media caused by carbon dioxide injection. The experiments revealed that the permeability and porosity significantly increased in samples composed of minerals soluble in an acidic environment, while permeability decreased in samples composed of acid-insoluble minerals. CT scanning confirmed the formation of wormholes in the samples.

Summary: The application of Saline Aquifer CO2 Storage (SACS) projects in offshore saline aquifers in China shows promising potential in terms of technical and economic viability. However, the storage capacities determined by different methods vary significantly. The CO2BLOCK method seems to provide more reasonable results and further confirms the immense potential of industrial-scale pilot and demonstration CO2 storage projects in offshore deep saline aquifers in China.

Summary: This paper numerically studied the geochemical reaction mechanism of CO2 storage in saline aquifers and its effects on the reservoir rocks and CO2 consumption. The results showed that the long-term geochemical reactions did not affect the porosity and permeability of the rocks and had no adverse consequences for extraction. The captured CO2 was distributed in gas, aqueous phase, and minerals, accounting for 27%, 65%, and 8% respectively. The study provides a theoretical reference for underground energy storage projects involving fluid-rock interactions.

Summary: Switzerland supports the development of geothermal energy by building a basin-scale fluid flow model in the Geneva Basin. The study investigates the distribution of temperature and pressure to identify thermal anomalies, proposing a conceptual model suggesting fluid flow is driven by meteoric waters cooling rocks at the basin edge. The approach could be used to assess geothermal resources in other sedimentary basins.

Summary: Representative low-cost materials were embedded in mortar to mimic the casing-mortar interface in injection wells. Two types of cement were investigated for their corrosion resistance, and exposure tests revealed unexpected corrosion types on steel surfaces. Surface analysis and element mapping were used to trace chloride intrusion and corrosion process on exposed specimens.

Summary: This study focuses on the well pattern arrangement in CO2 enhanced gas recovery (CO2-EGR). Mathematical models of five-spot and seven-spot well patterns are established and validated, and equipotential and streamline charts are derived. The relationships between well pattern parameters and gas production rate are investigated, and an optimization strategy is proposed.
