Hydrological evolution and biogeochemical feedbacks controlling organic carbon accumulation in an Eocene saline lake

Jian-Hua Zhao, W. X. Zhang, Keyu Liu, Qinhong Hu et autres

Organic carbon (OC) accumulation in lacustrine basins is commonly attributed to sustained anoxia and high primary productivity, yet the role of dynamic hydrological reorganization in carbon preservation remains poorly constrained. Here, we integrate multi-proxy sedimentological and geochemical data from the Eocene Kongdian …

Laminae Control on Pore Space Heterogeneity in Lacustrine Lucaogou Formation: Insights from SANS Studies

Wen Liu, Yufeng Xiao, Qinhong Hu, Zhenhua Xie et autres

Abstract Laminated shales in the Lucaogou Formation exhibit strong pore heterogeneity, and the quantitative relationship between lamina types and pore structure remains poorly constrained. This study investigates how different laminae control pore distribution, connectivity, and heterogeneity in shale reservoirs by using samples …

AI-4-SPS: An Artificial Intelligence-Driven Semantic Database for Shale Pore Structure Characterization

Chen Zhao, Peng Hu, Yi Yang, He Cheng et autres

Understanding shale pore structure across nano- to mesoscales is essential for reservoir evaluation, which supports effective geological exploration and development. However, this understanding remains constrained by data fragmentation across different methods and by the limited integration of small-angle neutron scattering (SANS), which …

Sequential Solvent Extraction Reveals Lithofacies-Dependent Pore Accessibility, Wettability, and Hydrocarbon Partitioning in Organic-Rich Lacustrine Shales

Qiming Wang, Weixing Yan, Qinhong Hu, Pengfei Jiao et autres

Understanding the reservoir characteristics of shale oil formations is an essential workflow in petroleum exploration and development because it supports petroleum-reserve evaluation and guides production activities. Few studies have examined the coupled effects of pore structure and oil composition on reservoir characterization, …

Comparative Study on Pore Characteristics and Methane Adsorption Capacity of Shales with Different Levels of Tectonic Deformation: A Case Study of Longmaxi Shales in Fuling Field

Xiaoming Zhang, Changcheng Han, Lanpu Chen, Qinhong Hu et autres

Tectonic deformation can substantially change the pore characteristics and the resulting methane adsorption capacity of shales; thus, it strongly influences shale gas exploration and development in structurally complex areas of southern China. Two sets of shales with identical lithofacies that were derived …
