Quantitative Characterization for Pore Connectivity, Pore Wettability, and Shale Oil Mobility of Terrestrial Shale With Different Lithofacies—A Case Study of the Jurassic Lianggaoshan Formation in the Southeast Sichuan Basin of the Upper Yangtze Region in Southern China

Some major hydrocarbon-bearing basins are rich in shale with terrestrial facies China, which may provide abundant oil and gas resources. This work studied the Jurassic Lianggaoshan Formation Southeast Sichuan Basin of upper Yangtze Region. Core samples were chosen for total organic carbon content mineral composition analyses to classify lithofacies. Afterward, pore connectivity, wettability, mobility different lithofacies characterized by spontaneous imbibition, nuclear resonance, centrifugation. Conclusions as follows: connectivity organic-rich clay was mostly between moderate good oil-prone wettability high mobile saturation. The mixed has water-prone highest Organic matter–bearing bad connectivity. Meanwhile, its covers wetting, wetting. Its saturation moderate. Regarding shale, mixed-wetting
