Many petroleum basins are impacted by subsurface anisotropy, which causes seismic velocities to vary according to compass direction (or azimuth). Unless properly accounted for, anisotropy degrades seismic image quality. ION's AXIS Geophysics team developed the AZIM imaging solution to account for directional velocity variations. Winner of the 2003 Hart’s E&P Meritorious Award for Engineering Innovation, the AZIM technique uses a full azimuth, non-sectoring approach to determine azimuthal-varying velocities. The results of AZIM include improved stratigraphic resolution, more accurate depth conversion, and a robust foundation for geologic interpretation of anisotropy that can be used to detect reservoir fracture patterns and to perform quantitative AVO.
Following ION’s acquisition of GX Technology (GXT) in 2004, AXIS Geophysics became a division within the GXT group. The development teams from both GXT and AXIS are now working closely together to incorporate anisotropic functionality into the processing tools developed by the other. As a result, the GXT group is able to offer a comprehensive suite of anisotropic imaging solutions to its oil & gas company customers including:
