    Nonlinear Gray-Level Co-Occurrence Matrix Texture Analysis for Improved Seismic Facies Interpretation.Haibin Di & Dengliang Gao - 2017 - Interpretation: SEG 5 (3):SJ31-SJ40.
    Seismic texture analysis is a useful tool for delineating subsurface geologic features from 3D seismic surveys, and the gray-level co-occurrence matrix method has been popularly applied for seismic texture discrimination since its first introduction in the 1990s. The GLCM texture analysis consists of two components: to rescale seismic amplitude by a user-defined number of gray levels and to perform statistical analysis on the spatial arrangement of gray levels within an analysis window. Traditionally, the linear transformation is simply used for amplitude (...)

    Seismic Structure and Texture Analyses for Fractured Reservoir Characterization: An Integrated Workflow.Dengliang Gao & Taizhong Duan - 2017 - Interpretation: SEG 5 (4):T623-T639.
    Fractured reservoir prediction is risky and challenging because of the variability in fracture characteristics and the lack of direct observational data in the subsurface. To reduce the risk and challenge, we have developed an integrated workflow to predict fractured reservoirs based on 3D seismic data. The workflow begins with reservoir structure analysis from seismic reflection geometry, which is referred to as seismic structure analysis, to define fracture intensity and fracture orientation using maximum curvature and maximum flexure algorithms. Next, the workflow (...)

    3D Structural-Orientation Vector Guided Autotracking for Weak Seismic Reflections: A New Tool for Shale Reservoir Visualization and Interpretation.Haibin Di, Dengliang Gao & Ghassan AlRegib - 2018 - Interpretation: SEG 6 (4):SN47-SN56.
    Recognizing and tracking weak reflections, which are characterized by low amplitude, low signal-to-noise ratio, and low degree of lateral continuity, is a long-time issue in 3D seismic interpretation and reservoir characterization. The problem is particularly acute with unconventional, fractured shale reservoirs, in which the impedance contrast is low and/or reservoir beds are below the tuning thickness. To improve the performance of interpreting weak reflections associated with shale reservoirs, we have developed a new workflow for weak-reflection tracking guided by a robust (...)

    Acadian Hinterland-Vergent Detachment Structures in the Southwestern Appalachian Plateau: Implications for the Marcellus Shale Gas Exploration and Production.Dengliang Gao, Thomas Donahoe, Taizhong Duan & Peter Sullivan - 2018 - Interpretation: SEG 6 (4):SN85-SN99.
    Three-dimensional seismic data in southwestern Pennsylvania in the Appalachian Plateau demonstrate that the structural style in the Devonian section is dominated by east-vergent folds and reverse faults, which contrasts with that in the Valley and Ridge Province where west-vergent folds and thrusts dominate. Vertical variations in fold curvature and fault throw indicate that the intensity of shortening increases from the Salina to the Onondaga and then decreases from the Onondaga to the Elk. Lateral variations in fold curvature and fault throw (...)

    Application of 3D Seismic Attribute Analysis to Structure Interpretation and Hydrocarbon Exploration Southwest Pennsylvania, Central Appalachian Basin: A Case Study.Thomas Donahoe & Dengliang Gao - 2016 - Interpretation: SEG 4 (3):T291-T302.
    In the Central Appalachian Basin, southwest Pennsylvania, recently collected high-quality 3D seismic data provide critical information vital to the delineation of basin structures and depositional facies. It is therefore important for the development and verification of ideas associated with structural architecture and growth history of the basin. Traditional wiggle trace imagery has a low dominant frequency and signal-to-noise ratio. The conventional seismic attributes extracted from this data set, such as amplitude, frequency, and phase, are not effective at defining structural details (...)

    Caledonian Detachment Deformation and Deposition in the Fuling Gas Field of the Southeastern Sichuan Basin in China: Implications for the Lower Silurian Longmaxi Shale Gas Exploration and Production.Dengliang Gao, Taizhong Duan, Zhiguo Wang & Xiaofei Shang - 2018 - Interpretation: SEG 6 (4):SN119-SN132.
    The Fuling gas field in the southeastern Sichuan Basin is the first and the largest shale gas play in China that has been producing primarily from the organic-rich shale in the Upper Ordovician Wufeng Formation and the Lower Silurian Longmaxi Formation. Newly processed 3D seismic data along with well-completion data in the gas field reveal important structural, depositional, and reservoir details in the Lower Paleozoic sedimentary section. Lateral variations in time structure and bed curvature demonstrate the diversity in faults that (...)

    Acadian Detachment and Wrench Faults in Central Pennsylvania: Implications for the Marcellus Shale Reservoir Integrity and Gas Productivity in the Hinge of the Pennsylvania Salient of the Appalachian Basin.Dengliang Gao, Emily Roberts, Connor Geiger & Peter Sullivan - forthcoming - Interpretation:1-56.
    High-quality 3D seismic data in Clearfield County, central Pennsylvania, reveal subsurface structural details of regional flat-top, box-shaped folds, convergent reverse faults and cross-regional lineaments in the hinge of the Pennsylvanian Salient. Cross-stratal variations in structural relief, bed curvature and seismic facies indicate that the intensity of deformation increases from below the Salina to the Onondaga, and then decreases from above the Onondaga to the Elk. Pre-Onondaga isochron thickness increases on the anticlinal axes, whereas post-Onondaga isochron thickness decreases on the anticlinal (...)

    Acadian Detachment and Wrench Faults in Central Pennsylvania: Implications for the Marcellus Shale Reservoir Integrity and Gas Productivity in the Hinge of the Pennsylvania Salient.Dengliang Gao, Emily Roberts, Connor Geiger & Peter Sullivan - 2020 - Interpretation 8 (1):T151-T165.
    High-quality 3D seismic data in Clearfield County, central Pennsylvania, reveal subsurface structural details of regional flat-top, box-shaped folds, convergent reverse faults, and cross-regional lineaments in the hinge of the Pennsylvanian salient. Cross-stratal variations in structural relief, bed curvature, and seismic facies indicate that the deformational intensity increases from below the Salina to the Onondaga and then decreases from the Onondaga to the Elk. The pre-Onondaga isochron thickness sees an increasing trend but the post-Onondaga isochron thickness sees a decreasing trend on (...)
