    Hydrocarbon Storage Space Within Lacustrine Gas Shale of the Triassic Yanchang Formation, Ordos Basin, China.Xiangzeng Wang, Lixia Zhang, Chengfu Jiang & Bojiang Fan - 2015 - Interpretation: SEG 3 (2):SJ15-SJ23.
    The Triassic Yanchang Formation lacustrine shale is a source of conventional oil accumulation in the Ordos Basin, China. The Yanchang Formation, a hybrid system of organic-rich shale, interbedded silty shale, and siltstone, is believed to be a potential unconventional oil and gas play. Our crossdisciplinary investigation of the storage space included the outcrop description, core observation, thin sections, and scanning electron microscope pore imaging. We evaluated the results from these techniques to reveal that the storage space within the Yanchang Formation (...)

    Liquid Hydrocarbon Characterization of the Lacustrine Yanchang Formation, Ordos Basin, China: Organic-Matter Source Variation and Thermal Maturity.Xun Sun, Quansheng Liang, Chengfu Jiang, Daniel Enriquez, Tongwei Zhang & Paul Hackley - 2017 - Interpretation: SEG 5 (2):SF225-SF242.
    Source-rock samples from the Upper Triassic Yanchang Formation in the Ordos Basin of China were geochemically characterized to determine variations in depositional environments, organic-matter source, and thermal maturity. Total organic carbon content varies from 4 wt% to 10 wt% in the Chang 7, Chang 8, and Chang 9 members — the three OM-rich shale intervals. The Chang 7 has the highest TOC and hydrogen index values, and it is considered the best source rock in the formation. Geochemical evidence indicates that (...)

    Study on the Distribution of Extractable Organic Matter in Pores of Lacustrine Shale: An Example of Zhangjiatan Shale From the Upper Triassic Yanchang Formation, Ordos Basin, China.Yuxi Yu, Xiaorong Luo, Ming Cheng, Yuhong Lei, Xiangzeng Wang, Lixia Zhang, Chengfu Jiang & Likuan Zhang - 2017 - Interpretation: SEG 5 (2):SF109-SF126.
    Shale oil and gas have been discovered in the lacustrine Zhangjiatan Shale in the southern Ordos Basin, China. To study the distribution of extractable organic matter in the Zhangjiatan Shale, geochemical characterization of core samples of different lithologies, scanning electron microscope observations, low-pressure [Formula: see text] and [Formula: see text] adsorption, and helium pycnometry were conducted. The content and saturation of the EOM in the pores were quantitatively characterized. The results show that the distribution of the EOM in the shale (...)

    Identification and Distribution of Fractures in the Zhangjiatan Shale of the Mesozoic Yanchang Formation in Ordos Basin.Hui Shi, Xiaorong Luo, Hui Xu, Xiangzeng Wang, Lixia Zhang, Qingchen Wang, Yuhong Lei, Chengfu Jiang, Ming Cheng & Shan Ma - 2017 - Interpretation: SEG 5 (2):SF167-SF176.
    The natural fractures in mud or shale directly affect the quality and efficiency of shale gas reservoirs, and fracture identification and prediction play an important role in drilling shale gas wells and making plans for reservoir stimulation. We adopted ant tracking technology for 3D poststack reflective seismic waves to identify the size and distribution of high-angle structural fractures in the Zhangjiatan shale of the Yanchang Formation in the Ordos Basin, which is a typical continental shale. The parameters for ant tracking (...)
