Summary: A systematic analysis was conducted on the Cambrian-Ordovician carbonate platform in the eastern Tarim Basin, revealing the development of various sub-facies and micro-facies. The depositional evolution of the platform was controlled by paleo-geomorphology and sea-level changes, resulting in the dominance of different facies during different periods. The distribution of paleo-geomorphologic units played a significant role in determining the types and distributions of carbonate platform facies. The transgression and regression of sea level also influenced the growth and distribution of reef-shoal complex and lime mud mound.

Summary: Based on various analyses, the study systematically determines the charge and evolution history of the YJ1X ultra-deep oil reservoir in the southwestern part of the Tabei Uplift. It reveals that the reservoir oil, free oil, and inclusion oil have similar characteristics and maturities, suggesting a common marine source. The study also identifies two types of oil inclusion assemblages in the reservoir and demonstrates that the reservoir experienced one oil charge during the Early Devonian and has been well preserved since.

Summary: The Tarim Basin is the only petroliferous basin enriched with marine oil and gas in China. It is also the deepest basin for petroleum exploration and development in the world. The marine petroleum in the basin has a mixed source of two main sets of marine Source Rocks. The sedimentary environment plays an important role in the formation and accumulation of high-quality source rocks in the basin.

Summary: The changes in the geological environment during the Middle-Late Ordovician transition are studied through geochemical evidence. It is found that the Saergan Formation in NW China exhibited enrichment in major and trace elements compared to post-Archaean Australian Shale, suggesting an active continental margin tectonic environment. The Middle-Late Ordovician was a transitional period with semiarid climate and hypersaline anoxic marine conditions.

Summary: Based on drilling cores, thin sections, and 3D seismic data, this study investigates the types, features, and evolution processes of Cambrian-Ordovician carbonate platforms in the Gucheng and Xiaotang areas. It identifies two types of carbonate platforms, namely carbonate ramp and rimmed platforms, and reveals the different evolution processes in the two areas. The study also discusses favorable exploration zones in this area.

Summary: This study focuses on the Neogene hydrocarbons of the Wensu uplift along with their geochemical characteristics and origin. The results show that crude oils from the Wensu uplift display typical lacustrine characteristics, distinct from the adjacent marine crude oils.

Summary: This study analyzes Cambrian shale samples from the Tarim Basin in northwestern China and finds significant differences in the mechanism of organic matter enrichment between the western intraplatform and the eastern basin, primarily influenced by paleoproductivity. The findings have important implications for our understanding of Early Cambrian shales.

Summary: The dolomitization of the thick carbonates in the Gucheng uplift in northwestern China has led to the formation of massive dolomite reservoirs. Different dolomite types formed under varied conditions, influencing their mineral compositions and porosity, which in turn affect the geological characteristics and oil and gas exploration in the area.

Summary: By analyzing the karst drainages and flowing channels in different paleogeomorphic units of the Tahe area, Tarim Basin, it was found that the differential structures of karst zone and hydrocarbon distribution lead to variations in oil and gas accumulation. The karst paleogeomorphy of Ordovician in Tahe area consists of watershed, karst valley, and karst basin, each with unique water flowing patterns contributing to differing levels of oil and gas production.

Summary: This study investigated the sedimentary differentiation and anisotropy of magnetic susceptibility (AMS) of the Tarim Carbonate Platform (TCP) in order to infer the paleowind directions during each epoch of the Cambrian-Ordovician and constrain its paleogeographic location. The results showed that the prevailing wind directions of the Early, Middle, and Late Cambrian were 226 degrees +/- 42 degrees, 207 degrees +/- 43 degrees, and 193 degrees +/- 36 degrees from present north, respectively, while those of the Early, Middle, and Late Ordovician were 178 degrees +/- 39 degrees, 165 degrees +/- 43 degrees, and 155 degrees +/- 52 degrees from present north, respectively.

Summary: This study quantifies the distribution and tectono-sedimentary characteristics of the Cambrian gypsum-salt rocks in the Tarim Basin, using geological data from outcrops, well logs, rock cores, and seismic reflection profiles. The gypsum-salt rocks are mainly distributed in the Lower Cambrian Wusonger and the Middle Cambrian Awatage Formations, around the Aman and Awati depressions and the Bachu uplift. These lithofacies are associated with different environments of deposition. The study provides new insights for sub-salt and inter-salt hydrocarbon exploration in the Tarim Basin.

Summary: The study showed that the Ordovician crude oil samples have similar molecular compositions and genetic relationships, but maturity parameters indicated maturity variations. The samples displayed characteristics of mixtures of biodegraded and fresh oil, possibly originating from Middle - Upper Ordovician source rocks.

Summary: The geochemical analysis of natural gas in four different fault zones revealed that the natural gas in the North Shuntuoguole area in the Tarim Basin is associated with oil. The changing trends of K-1 and K-2 values indicated that the natural gas in the Shunbei area comes from the same oil and gas system.

Summary: In this study, five types of hydrocarbon expulsion dynamics were studied to understand the mechanism of hydrocarbon expulsion from deep source rocks. A model was proposed to evaluate the relative contribution of different dynamics using mass balance principle, and it was applied to Cambrian source rocks in the Tarim Basin. The results showed that capillary pressure difference (CPD) had the largest contribution (>50%), followed by compaction, product volume expansion, and thermal expansion. Diffusion had minimal contribution. The research categorized the hydrocarbon expulsion process into three stages based on the dominant dynamics, providing insights for hydrocarbon exploration in tight oil and gas reservoirs.

Summary: The Arctic Alaska petroleum province is geologically and geochemically complex, with mixed hydrocarbon charge from multiple source rocks and levels of thermal maturity. Biomarker and chemometric statistical analyses reveal that most oils are derived from specific source rocks, but also indicate mixed-oil accumulations with postmature contributions in some cases.
