Summary: Three abundant rearranged oleananes were identified in Tertiary oils from the Baiyun Sag, South China Sea, and their relative abundances were found to be correlated with each other and with oleanane and des-A-oleanane. The distribution of rearranged oleananes in the oils is mainly controlled by angiosperm inputs and diagenetic conditions. Oligocene marine transgression and peat swamp conditions are believed to have played important roles in the expression and formation of these compounds. These rearranged oleananes can be used as effective indicators for oil-oil or oil-source rock correlation in the study area.

Summary: In this study, oxygen- and sulfur-containing compounds were found to be good alternatives to pyrrolic nitrogen compounds for studying oil migration. A gas purge microsyringe extraction (GP-MSE) device was developed and combined with comprehensive two-dimensional gas chromatography/time-of-flight mass spectrometry (GC x GC-TOFMS) for simultaneous analysis of target compounds. Oil samples from the Zhu I Depression in the South China Sea were classified based on their geochemical distribution characteristics, carbon isotope parameters, and concentrations of specific compounds. The study also used molecular dynamics (MD) simulation to gain nanoscale insights into geochromatographic fractionation and the interaction between polar compounds and clay minerals during oil migration.

Summary: This research paper investigates the hydrocarbon generation and accumulation in the Progreso Basin Province of the southern coastal region of Ecuador through an organic geochemical analysis of oils and sedimentary rocks. The study reveals that almost all oils from this province underwent biodegradation and were generated from multiple Tertiary source rocks in a marine environment with terrestrial organic material influx. The research also establishes correlations between source facies and oil samples, identifying three families of oils. Furthermore, geochemical data suggest the presence of two probable hydrocarbon kitchens in the deepest parts of the basin and a potential offshore kitchen beyond the Santa Elena Peninsula.

Summary: This paper studies the far-source oil and gas reservoirs in the Dongsha Uplift of the northern South China Sea. By comparing the characteristics of crude oil and source rocks and using simulation software, the migration paths and formation time of oil and gas are analyzed from a dynamic perspective. The study found that the accumulation of hydrocarbons far from the source rocks in the Dongsha uplift is mainly controlled by the efficient carrier system, and is mainly accumulated in the L41 and L11-1 oil fields. The spatial and temporal relationship between hydrocarbon generation of source rock and episode of fault activity are mainly responsible for the accumulation in the far-source reservoirs of the Dongsha Uplift.

Summary: The accurate understanding of the origin of overpressure is crucial in formation pressure research and drilling design. The Pearl River Mouth Basin in the South China Sea has been identified as a hydrocarbon rich area. In this study, the pore pressure profile of Baiyun Sag was evaluated using drilling and seismic velocity data. Overpressure was found in the middle and deep layers, and it was concluded that the overpressure is caused by fluid expansion from hydrocarbon-generation. The distribution of effective source rocks plays a controlling role in the distribution range of overpressure.

Summary: Marine-terrestrial transitional Permian shales in South China have favorable conditions for shale gas accumulation but have not been commercially exploited. This study investigates the methane adsorption characteristics of Permian shales in the Lower Yangtze area, focusing on the influences of TOC content and temperature. The results show that organic matter pores in shale play a significant role in methane storage. However, the underdeveloped pore structure of Permian shales leads to lower methane adsorption capacities compared to marine shales. It is recommended to explore Permian shales with high TOC contents, high porosity, and deep burial for future exploration efforts.

Summary: This study investigates the gas-bearing property of coal-measure shale in the Qinshui Basin, North China. The results show that the shale has ultra-low saturation pore water, mainly in clay minerals, which significantly reduces its pore structure parameters and methane adsorption capacity. The adsorption of methane is controlled by the TOC content and decreases with increasing temperature. Pore water competes with methane for adsorption and weakens the inter-molecular interaction forces, especially at low temperature and pressure conditions.

Summary: Low-resistance shale reservoirs, which have higher yields in high-mature shale gas plays, are influenced by the degree of graphitization and pore structure of organic matter. High graphitization significantly reduces rock resistivity and changes the mechanical properties of organic matter. The change in organic pore size and shape leads to a decrease in resistivity, while graphitization exceeding 15% results in poor pore development and increased exploration risk.

Summary: Quartz cement is an important authigenic mineral in the tight sandstones of the Shaximiao Formation in the Sichuan Basin. This study analyzed the silicon sources of the quartz cement using mineralogical, fluid inclusion, and geochemical data. The results showed that smectite alteration and dissolution of aluminosilicate minerals were the primary sources of silicon for quartz cementation. Contributions from volcanic material hydrolysis and pressure solution were relatively minor. The presence of chlorite films inhibited the development of quartz overgrowths and had minimal impact on reservoir quality.
