    Characterization of Gas Hydrate Distribution Using Conventional 3D Seismic Data in the Pearl River Mouth Basin, South China Sea.Xiujuan Wang, Jin Qian, Timothy S. Collett, Hesheng Shi, Shengxiong Yang, Chengzhi Yan, Yuanping Li, Zhenzhen Wang & Duanxin Chen - 2016 - Interpretation: SEG 4 (1):SA25-SA37.
    A new 3D seismic reflection data volume acquired in 2012 has allowed for the detailed mapping and characterization of gas hydrate distribution in the Pearl River Mouth Basin in the South China Sea. Previous studies of core and logging data showed that gas hydrate occurrence at high concentrations is controlled by the presence of relatively coarse-grained sediment and the upward migration of thermogenic gas from the deeper sediment section into the overlying gas hydrate stability zone ; however, the spatial distribution (...)

    Gas Hydrate Accumulation and Saturations Estimated From Effective Medium Theory in the Eastern Pearl River Mouth Basin, South China Sea.Jin Qian, Xiujuan Wang, Timothy S. Collett, Dongdong Dong, Yiqun Guo, Pibo Su & Jinqiang Liang - 2017 - Interpretation: SEG 5 (3):SM33-SM48.
    Pore- and fracture-filling gas hydrates were identified from the core samples at several sites during the second Guangzhou Marine Geological Survey expedition. Well logs indicated that gas hydrate occurred in three distinct layers at site GMGS2-08. The gas hydrate saturations calculated from well-log data and the seismic responses for the three gas hydrate-bearing layers, especially within the middle carbonate layer, were poorly known. We estimated gas hydrate saturations using isotropic and anisotropic models based on the mineral composition of the sediments (...)

    The Role of Fluid Migration in the Occurrence of Shallow Gas and Gas Hydrates in the South of the Pearl River Mouth Basin, South China Sea.Jinxiu Yang, Xiujuan Wang, Jiapeng Jin, Yuanping Li, Jie Li, Jin Qian, Hesheng Shi & Guangxu Zhang - 2017 - Interpretation: SEG 5 (3):SM1-SM11.
    High-amplitude anomalies, bottom-simulating reflectors, vertical acoustic blanking features, polygonal faults, and mass transport complexes are observed in high-resolution 3D seismic data from the south of the Pearl River Mouth Basin, South China Sea. We have focused on the role of fluid migration in the occurrence of shallow gas and gas hydrates. HAAs are interpreted to be shallow gas accumulations or gas hydrates, depending on their polarity and the presence of BSRs. Acoustic blanking features are probably caused by the presence of (...)
