  1. Coal and Shale Distributions on Half-Graben Slopes: A Case Study of the Eocene Pinghu Formation in Xihu Sag, East China Sea.Donghui Jiang, Sujie Yan, Renhai Pu, Siyu Su, Feng Zhou & Qinglong Chen - 2022 - Interpretation 10 (3):T403-T413.
    Steep and gentle slopes in a half-grabben basin often form oil source rocks of coal and shale. However, which source rock is dominant and what the relation is with the slope type and sedimentary facies are not clear. The Pinghu Formation in Xihu Sag is a half-graben basin with coal seam as the main source rock. Five condensate reservoirs have been found in its west slope, with several wells and 3D seismic data, which makes it possible to study the relationship (...)

  2. Characteristics and Origins of Ridges and Troughs on the Top of the Middle Miocene Strata in the Beijiao Sag of the Qiongdongnan Basin, Northern South China Sea.Yufeng Li, Renhai Pu, Gongcheng Zhang & Hongjun Qu - 2021 - Interpretation 9 (2):SB1-SB15.
    Sedimentary structures generated by bottom currents are of interest to geologists. Based on the root mean square, coherence attribute, and 3D representations, ridges and troughs are imaged for the first time using 3D high-resolution seismic data and confirmed by a well, YL19-1-1, in the Beijiao Sag of the Qiongdongnan Basin. Combined with 2D seismic profiles, we define the flow direction of bottom currents resulting in ridges and troughs. The results indicate that ridges and troughs occur on the top of the (...)

    Seismic Interpretation of the Diapiric Structures and Gas Chimneys in the Liwan Gas Field, Pearl River Mouth Basin, Northern South China Sea.Xiaochuan Wu, Renhai Pu, Gongcheng Zhang, Xiaowei Fan, Dong Deng & Bin Li - 2018 - Interpretation: SEG 6 (3):T499-T519.
    Voluminous diapiric intrusions are present in 3D seismic data from the Liwan gas field area in the Baiyun sag of the Pearl River Mouth Basin, South China Sea. These diapirs are subdivided into magmatic diapirs and mud diapirs according to their seismic signatures and formation mechanisms. Saucer- and mound-shaped reflectors with anomalously high amplitudes distributed throughout the Early Miocene strata are interpreted as sills and laccoliths and are typified as magmatic diapirs. Mud diapirs in the study area can be divided (...)

    The 3D Seismic Characteristics and Significance of the Strike-Slip Faults in the Tazhong Area.RenHai Pu, KunBai Li, Machao Dong, ZiCheng Cao & Pengye Xu - 2019 - Interpretation 7 (1):T1-T19.
    The eastern part of Tazhong area in the Tarim Basin consists of three sets of vertical strike-slip faults oriented in north–northeast, east–northeast, and west–northwest directions that cut the strata from Cambrian to Carboniferous. The fault belts indicate significant horizon upwarp and downwarp deformations and variations in their stratigraphic thickness on seismic profiles. Through detailed interpretation of the 3D seismic data, we consider that these phenomena reflect the different stress properties and active stages of the faults. The horizon upwarp and downwarp (...)

    Three-Dimensional Seismic Analysis of Late Paleozoic Coal-Bearing Series Reflections in the Hangjinqi, North Ordos Basin, China.Xiaochuan Wu, Renhai Pu, Dong Deng, Donghui Wang & Machao Dong - 2019 - Interpretation 7 (1):T67-T82.
    The study of sand bodies and coalbeds that formed during strong events is conducive to understand the relationship between source rocks and reservoirs. Two sets of Late Paleozoic coal-bearing sequences including the Late Carboniferous Taiyuan Formation and Early Permian Shanxi Formation, with an accumulated thickness of more than a half wavelength, were deposited in the Hangjinqi region on the northern margin of the Ordos Basin. These strata appear as two peaks and two troughs, three peaks and three troughs in the (...)

    Analysis of Vertical Position Relationships Between Igneous Sills and an Unconformity Surface — Interpretation of Seismic Profiles From the Northern Tarim Basin, NW China.Tianyu Ji, Wei Yang, Renhai Pu, Xueqiong Wu & Xiaochuan Wu - 2020 - Interpretation 8 (4):T739-T752.
    Sill emplacement mechanisms are very complex, diverse, and regional, and insights from sill reflections are helpful for understanding the emplacement process of magma in the Tarim Basin. This study takes advantage of high-quality 2D seismic data, which are rarely used to study sills in the Tarim Basin, to analyze the sills’ geometric characteristics, plan-view distributions, emplacement timing, and emplacement mechanisms with unconformity surfaces. In the seismic-reflection profiles of the middle-upper Ordovician in the North depression and the southern part of the (...)

    Determining 3D Seismic Characteristics of the Conduit System of the Changchang Sag, Qiongdongnan Basin.Yufeng Li, Renhai Pu, Gongcheng Zhang, Qiang Han, Chao Yuan & Xueqin Zhao - 2021 - Interpretation 9 (2):T283-T297.
    Although some giant gas fields found in the deepwater area of the Qiongdongnan Basin, China, are often associated with mud diapirs and/or gas chimneys, no comprehensive 3D work has been undertaken to characterize them. We have conducted a 3D seismic investigation using the root-mean square, coherence, and instantaneous frequency attributes to provide a better understanding of the conduit systems in the QDNB. The results show that the conduit system that we investigated can be separated vertically into four zones in the (...)

    Although some giant gas fields found in the deep-water area of the Qingdongnan Basin, China, are often associated with mud diapirs and/or gas chimneys, no comprehensive 3D work has been undertaken to characterize them. We conducted 3D seismic investigation using root mean squares, coherence, and instantaneous frequency attributes to provide better understanding of the conduit systems in the Qiongdongnan Basin. The results show that the conduit system that we investigated can be separated vertically into four zones in the following order. (...)
