  1. Diffraction Imaging for the Fault-Karst Structure by Least-Squares Reverse Time Migration.Xinru Mu, Jianping Huang, Liyun Fu, Shikai Jian, Bing Hu & Ziying Wang - 2021 - Interpretation 9 (2):T385-T394.
    The fault-karst reservoir, which evolved from the deformation and karstification of carbonate rock, is one of the most important reservoir types in Western China. Along the deep-seated fault zones, there are a lot of widely spread and densely distributed fractures and vugs. The energy of the diffractions generated by heterogeneous structures, such as faults, fractures, and vugs, is much weaker than that of the reflections produced by continuous formation interface. When using the conventional full-wavefield imaging method, the imaging results of (...)

  • Investigation of Fluid Effects on Seismic Responses Through a Physical Modeling Experiment.Chao Xu, Pinbo Ding, Bangrang Di & Jianxin Wei - 2021 - Interpretation 9 (1):T213-T222.
    We have investigated fluid effects on seismic responses using seismic data from a physical modeling experiment. Eight cubic samples with cavities quantitatively filled with air, oil, and water and 16 nonfluid samples were set within a physical model. The pre- and poststack seismic responses of the samples were analyzed to quantitatively investigate the fluid effect on the seismic response. We determined that fluids could cause detectable changes in pre- and poststack seismic responses for tight rocks. At first, fluids filled within (...)

  • Calibration of Attribute Anomalies Through Prestack Seismic Modeling.Sumit Verma, Onur Mutlu, Thang Ha, William Bailey & Kurt J. Marfurt - 2015 - Interpretation: SEG 3 (4):SAC55-SAC70.
    Seismic modeling is commonly used in determining subsurface illumination of alternative seismic survey designs, in the calibration of seismic processing and imaging algorithms, and in the design of effective processing workflows. Seismic modeling also forms the mathematical kernel of impedance inversion and is routinely used to predict the amplitude-variation-with-offset response as a function of rock and fluid properties. However, the use of seismic modeling in seismic attribute studies is less common. We have evaluated four case studies in which 2D synthetic (...)

  • Interpretation of Paleozoic Paleokarst Features in the Arkoma Basin of Oklahoma Using 3D Seismic and Well Logs.Olanrewaju Aboaba & Christopher Liner - 2020 - Interpretation 8 (2):T421-T440.
    Paleokarst regions worldwide are repositories for hydrocarbons, mineral deposits, and groundwater. Time structure maps were generated for the Ordovician Viola Limestone, Mississippian Caney Shale, and Pennsylvanian Jefferson Sandstone and Wapanucka Limestone. Isochron maps indicate pronounced visible sinkhole time thickening in the Viola-Caney and Caney-Jefferson intervals relative to the Jefferson-Wapanucka. Sinkhole features in the Viola exhibit mappable structural depression, characterized by lower positive amplitude, higher seismic variance, and most-negative curvature. Curiously, spatially coincident sinkhole features in the shallower Wapanucka display the opposite (...)
