Please join us with for an esymposium with Tony Rebec on the latest developments for 3D seismic and resource plays, specifically the Marcellus shale. This presentation, to take place at 2 pm on November 3, demonstrates how 3D seismic data contributes 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
    • Â
      • 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
