Summary: This study conducted systematic experimental characterization to understand the pore structures and methane sorption in deep-marine shales. The results showed that factors such as organic matter content and clay minerals affect the pore structures and sorption behaviors in deep shales. The findings also indicate that deep shales have higher micropore content from organic matter and lower macropore content from clay minerals compared to shallow shales. The total organic carbon (TOC) content is the primary controlling factor on pore structure and sorption capacity in deep shales, while the influence of clay minerals on gas sorption is less pronounced.

Summary: Exploring the relationship between formation pressure and shale pore evolution is crucial for the development of marine shale gas accumulation theory. Experimental investigations on lowly matured marine shale were carried out to characterize the effects of formation pressure on shale pore morphology and hydrocarbon expulsion. The findings suggest that formation pressure promotes the expulsion of hydrocarbons, changes shale pore morphology, and improves pore connectivity. These results provide valuable insights into understanding the evolution of shale pore structures under different pressure conditions.

Summary: To accurately and comprehensively analyze the properties of organic nanopores in marine shale, an integration method using helium ion microscope (HIM), scanning electron microscope (SEM), focused ion beam-HIM (FIB-HIM), and FIB-SEM was proposed. Results showed that organic pores below 10 nm significantly impact shale gas storage and productivity evaluation by affecting porosity, surface area, pore size distribution, and connectivity characteristics. The integration method revealed an increase in surface porosity by 10.73% and an increase in specific surface area by 76%. It also showed that the formation of organic nanopores occurs in multiple stages, with larger bubble pores appearing during oil generation and smaller spongy pores appearing during gas generation. The organic pores revealed by FIB-HIM exhibited higher coordination numbers and a higher proportion of inner-connected volume, indicating more complex connectivity characteristics. Despite limitations, these novel insights highlight the importance of exploring organic nanopores at the nanoscale and have the potential to inform further research in this field.

Summary: This study focuses on the analysis of major hydrocarbon-bearing basins in China that are rich in shale with terrestrial facies, with a particular emphasis on the Jurassic Lianggaoshan Formation in the Southeast Sichuan Basin. The study investigates the pore connectivity, pore wettability, and shale oil mobility of different shale lithofacies using various analytical techniques. The results show that organic-rich clay shale and mixed shale have good pore connectivity, while organic matter-bearing clay shale has moderate connectivity. The wettability and mobile oil saturation also vary among different lithofacies.

Summary: The wettability behaviors of nanoscale pores in shales from the Longmaxi Formation in the Sichuan Basin were investigated. It was found that organic matter pores and inorganic pores in shales show cross-distribution. The spontaneous imbibition of oil is slower than that of water and increases with the total organic carbon content. Illite and quartz mineral surfaces are hydrophilic. The wetting contact angle of the organic matter surface increases with the increase in oxygen-containing functional groups but decreases with increasing temperature.

Summary: This study investigates the reservoir conditions of lacustrine shale in the Sichuan Basin through experiments on samples from wells and outcrops. The results show that lacustrine shale has different pore characteristics compared to marine shale. The arrangement of pores in marine shale is affected by compaction, while lacustrine shale is characterized by under-compaction. The findings suggest that high-quality areas for lacustrine shale gas may be located in under-compacted regions influenced by upward fluid pressure.

Summary: This study investigates the variation of organic matter occurrence and the relationship between petroleum generation of organic matter and transformation of clay minerals in nanocomposites as a function of maturity. The results show that most shale samples are organic-rich and represent a thermal evolutionary process from oil-window mature to overmature. The structural investigation of nanocomposites reveals that organic carbon dominates the occurrence of organic matter and extends the traditional view of organic matter-clay association. The results contribute to a better understanding of diagenesis and organic-inorganic interactions in organic-rich shales.

Summary: A study on 12 lacustrine shale samples from Lucaogou Formation reveals that the mineral compositions and organic matter abundance influence the pore system development and retained oil distribution. The samples are dominated by mineral-related slit-shaped pores with a small amount of organic matter-hosted pores. Feldspar dissolution leads to abundant dissolved pores, improving reservoir properties. Quartz overgrowth negatively affects pore structure, while carbonates undergo dissolution and cementation processes. Mineral sizes are positively related to pore diameter, and source-proximal sedimentary microfacies with coarse components are more favorable for oil exploration. Retained oil primarily occurs as a thin film in pores with diameters of 100-1500 nm, while oil in smaller pores is adsorbed. The retained oil volume is affected by organic matter abundance, storage type, and material source-reservoir configurations.

Summary: This study investigates the pore-fracture connectivity in overmature marine shale samples using small-angle neutron scattering (SANS), repeated mercury intrusion capillary pressure (MICP), and field emission scanning electron microscopy (FE-SEM) imaging. The results show that sealing of the pore system by brittle minerals reduces overall pore connectivity within the shale matrix. The combination of MICP measurements and FE-SEM imaging provides a new evaluation method for pore-fracture connectivity. The study also reveals that a small fraction of pores in overmature shales are accessible to methane, and under high pressure, the density of methane in small pore spaces is greater than that of an ideal gas and forms nanoscale methane clusters.

The supercritical Dubinin-Radushkevich (SDR) model was determined to be the most accurate model for fitting the measured excess adsorption. The adsorption of methane on mudstone is a physisorption process controlled by the heterogeneity and interaction forces between the methane molecule and the rock surface.

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.
