Fault Mapping In 3d Seismic Reflection Data Using Seismic Attributes And Velocity Anisotropy: Example From West Virginia, Megan Valdez

Graduate Theses & Non-Theses

Fracture characterization is highly important in the oil and gas industry. Knowing the location of fractures allows for the assessment of reservoir quality, aids in well placement and planning, and helps identify locations of possible traps. Fracture locations can be determined using seismic data for attribute calculations and anisotropy analysis. Attribute calculations, such as coherence and curvature, identify subtle changes in the dataset that conventional seismic data interpretation might overlook. Anisotropy analysis looks at directionally dependent variations in the wave propagation velocity. Fractures slow the propagation velocity of a wave if the fractures are perpendicular to the wave direction. A …
