Azimuthal Anisotropy (AZIM)

Many petroleum basins are impacted by subsurface anisotropy, causing seismic velocities to vary according to azimuth. Unless properly accounted for, anisotropy degrades seismic image quality.

Our GX Technology processing group developed the AZIM imaging solution to account for directional velocity variations. The results of AZIM provide a robust foundation for geologic interpretation of anisotropy that can be used to detect reservoir fracture patterns and to perform quantitative AVO.

Benefits from AZIM Anisotropic Imaging

  • Robust, high density (spatial and temporal) velocity analysis
  • Isotropic or anisotropic velocity solutions
  • Improved reflector continuity, fault imaging, and stratigraphic resolution
  • Improved gather conditioning for AVO analysis

Using the natural anisotropy of the rock, AZIM helps unlock the value of wide azimuth 3D and full-wave (multicomponent) data. Additionally, image quality of older 2D and 3D surveys can be improved by the high-resolution velocity information.

AZIM has been used successfully to help drive important drilling decisions in a variety of basins, ranging from the North Slope of Alaska to the Middle East.
