The Marcellus Shale Revealed with Full Azimuth 3D Multi-Component Seismic Data

Published
American Association of Petroleum Geologists (AAPG)

This presentation demonstrates how 3D seismic data will contribute significantly to the understanding of the Marcellus. Geophysical analysis and evaluation, although in the early stages, look very promising for optimizing well locations.

Topics include:
  • Introduction to the Marcellus Shale/data
  • Vertical Calibration & Resolution
  • Spatial Resolution & Geometric Attributes
  • Anisotropic/Rock Property Attributes
  • Density and Orientation of Micro-fractures
  • Physical Basis
  • Velocities dependence on fractures’ direction
  • Orientation
  • Velocity Ellipse
  • Difference between fast and slow velocities (anisotropy) is a measure of fracture density
  • Elliptical Inversion (EI) to estimate anisotropy
  • Conclusions
