Summary: Free hydrogen detected in the Songke-2 well in the Songliao Basin, China has a strong crustal contribution. Molecular hydrogen is generated after late hydrocarbon gas generation is complete. While storage in organic matrices is unlikely in this depositional setting, the prolific generation of hydrogen from organic sources in the region appears to be a reality.

Summary: In this study, evaluation indicators were selected to assess the suitability of the Beibu Gulf Basin for carbon dioxide (CO2) geological storage. The results indicated that the basin is suitable for CO2 storage, with high ratings. It is recommended to select target areas with suitable burial depth, superior reservoir conditions, proximity to CO2 collection devices, and a high degree of exploration for CO2 storage, considering techno-economic feasibility.

Summary: Fracture aperture uncertainty in reservoir modeling is attributed to challenges in quantifying aperture accurately and limited understanding of its controlling factors, making theoretical evaluation crucial. Combination of physical experiments and numerical simulations is effective in determining fracture apertures in underground reservoir conditions. Vertical distribution of in situ stress plays a significant role in determining average fracture aperture in rocks at different depths.

Summary: This study investigates the impact of formation attributes and controllable factors on CO2 storage capacity through simulation experiments and data analysis. The results demonstrate that injection temperature and formation slope significantly influence CO2 storage capacity. It was also found that higher injection temperature and smaller formation slope are more conducive to CO2 storage.

Summary: This study found that microbial action in deep saline aquifer has a positive influence on CO2 geological storage, increasing the amount of injected CO2 and enhancing CO2 mineral sequestration. Microbes promote dissolution of minerals at the initial stage and accelerate precipitation of carbon-fixing minerals at later stages, improving CO2 storage security.

Summary: This study investigates the organic matter-rich intervals in the Cretaceous succession of the Songliao Basin in northeastern China and examines the influences of global and regional factors on organic matter accumulation. The analysis of well logs, drill cores, and geochemical data reveals higher salinity stratification and stronger anoxia in the Southeastern Uplift compared to the Central Depression. The research also suggests that two separate depocenters might have existed during the deposition of the lowermost and most organic-rich sub-unit. The study provides direct evidence that basin segmentation strongly controlled the distribution of organic matter-rich rocks in the Qingshankou Formation.

Summary: Geological CO2 storage is a promising approach to mitigate global carbon emissions, and saline aquifers and oil/gas reservoirs have been proven to be the most suitable storage sites. This paper proposes a novel strategy of enhancing CO2 storage capacity by synthesizing and utilizing high-dryness CO2 foam. Through experiments, it is confirmed that the new foam can effectively increase storage capacity and reduce water consumption.

Summary: Based on research methods for petroleum systems, this study analyzed the characteristics of source rocks, reservoir rocks, caprocks, and the process of hydrocarbon generation, trap evolution, and oil accumulation in the oil-bearing assemblage in the Shuangcheng area of the northern Songliao Basin, NE China. The source rocks are mainly found in the Cretaceous Yingcheng Formation (K1yc), with high-quality organic abundance originating from lower aquatic organisms and algae. The crude oil generated from the K1yc source rocks has low density, high freezing point, and high wax content. The reservoir rocks consist of K1d sandstones and K1yc glutenites, and the oil was accumulated during specific periods. The traps evolved in three stages, forming structural and structural-lithologic reservoirs. It is concluded that the favorable factors for oil reservoir formation include a good source-reservoir-caprock assemblage, late hydrocarbon charging, short migration distance, and stable tectonic setting.
