    Fault Damage Zone at Subsurface: A Case Study Using 3D Seismic Attributes and a Clay Model Analog for the Anadarko Basin, Oklahoma.Zonghu Liao, Hui Liu, Zheng Jiang, Kurt J. Marfurt & Ze’ev Reches - 2017 - Interpretation: SEG 5 (2):T143-T150.
    Using 3D seismic attributes and the support of a clay model that served as an analog, we mapped and analyzed a 32 km long, north–south-striking, right-lateral fault in the Woodford Shale, Anadarko Basin, Oklahoma, USA. Volumetric coherence, dip azimuth, and curvature delineated an approximately 1.5 km wide damage zone with multiple secondary faults, folds, and flexures. The clay analog enabled us to identify these features as belonging to a complex transpressional Riedel structure. We also suggest that the damage zone contains (...)

    Fault Damage Zone Characterization in Tight-Oil Sandstones of the Upper Triassic Yanchang Formation in the Southwest Ordos Basin, China: Integrating Cores, Image Logs, and Conventional Logs.Wenya Lyu, Lianbo Zeng, Zonghu Liao, Yuanyuan Ji, Peng Lyu & Shaoqun Dong - 2017 - Interpretation: SEG 5 (4):SP27-SP39.
    Fault damage zones around faults have a significant influence on fluid flow in tight-oil sandstones because they commonly act as localized conduits. Faults are developed in the tight-oil sandstones of the Upper Triassic Yanchang Formation in the southwest Ordos Basin, China. We integrate cores, image logs, and conventional logs from vertical wells to characterize subsurface fault damage zones in the tight-oil sandstones of the Upper Triassic Yanchang Formation in the southwest Ordos Basin, China. The results indicate that fault damage zones (...)

  3. Collapse Columns in Permian and Carboniferous Formations of Coal, Qinshui Basin, China.Zonghu Liao, Lin Zhang, Long Wen & Lianbo Zeng - 2020 - Interpretation 8 (4):SR33-SR35.
    Seismic survey data collected for coal gas exploration show that there are many collapse columns distributed in the subsurface of Qinshui Basin, China. The interesting features of the collapse columns are observed by the seismic attributes, including the circular discontinuous patches on the horizon of the Shanxi Formation and multiple parallel discontinuities in vertical profiles of amplitudes. We speculate that the wide presence of these collapse columns are point constraints for the migration and accumulation of coal gas on a large (...)

    Multiscale Fracture and Damage Zone Characterization in a Tight Sandstone Reservoir, Sichuan Basin, China.Zonghu Liao, Weilun Chen, Xiaofeng Chen, Huayao Zou & Fang Hao - 2020 - Interpretation 8 (4):SP1-SP11.
    Fractures within fault damage zones are crucial for the migration of subsurface fluids, which is challenging the characterization of the fractures and damage zones in the subsurface due to the lack of subsurface data. We have investigated the fractures and fault damage zones in the tight sandstone gas-bearing Xujiahe Formation in the northeast Sichuan Basin, China, based on a comprehensive study of seismic data, well log, core, as well as field observations. We have demonstrated the structure and distribution of damage (...)

    Fracture Behavior of Longmaxi Shale with Implications for Subsurface Applications.Zonghu Liao, Shunjie Deng, Xiaofeng Chen, Mengni Wu, Yongshang Kang, Lianbo Zeng & Huayao Zou - 2020 - Interpretation 8 (4):SP205-SP213.
    Fracture mechanical properties of shales have gained continued interest recently due to their critical role in many shale-related applications such as unconventional petroleum systems and subsurface carbon and waste disposal. However, due to their strong reactive nature to fluids, fracture mechanical properties of shales have not been extensively studied like other rock types. A more comprehensive understanding of fracture system development in shales under reactive fluids is needed for subsurface applications. We have measured fracture mechanical properties of Longmaxi shale outcrop (...)

    Effect of Main Frequencies on Characterizing Fault Damage Zones Using Forward Modeling and Attribute of Variance.Yangpu Chen, Zonghu Liao, Li-Yun Fu, Gang Zhou, Liang Xu, Kurt J. Marfurt, Xinru Mu & Huayao Zou - 2020 - Interpretation 8 (4):SP157-SP165.
    Faulting processes have created large damage zones with complex structures in the field; however, estimating the width and geometry of such fault structures in the subsurface is challenging due to a lack of data. Seismic attributes from seismic surveys have been used for the characterization of faults, but most cases do not detail the effectiveness of this approach. By using forward modeling and the associated seismic attributes of variance, four fault models of idealized damage zones are characterized and the frequency (...)

    Characterizing Damage Zones of Normal Faults Using Seismic Variance in the Wangxuzhuang Oilfield, China.Zonghu Liao, Luyao Hu, Xiaodi Huang, Brett M. Carpenter, Kurt J. Marfurt, Saiyyna Vasileva & Yun Zhou - 2020 - Interpretation 8 (4):SP53-SP60.
    We have investigated the distribution and thickness of damage zones for a system of secondary normal faults in the subsurface of the Wangxuzhuang oilfield, China. Based on seismic variance analysis, we find four isolated faults with approximately 2 km length and approximately 200 m damage-zone thickness. The damage zones of these isolated faults reveal a decaying intensity of deformation from the fault core to the protolith, which fits a power-law form [Formula: see text] similar to that observed in the field.
