Term · Oil and gas · MLC-T-OAG-003834

A form of seismic anisotropy where the velocity of a wave depends on its direction of travel relative to a single axis of symmetry, with the wave speed being constant in the plane perpendicular to this axis. This condition is caused by fine layering in sedimentary rocks like shale or by aligned fractures, requiring specialized processing to correctly image subsurface structures and predict rock properties. The two main types are Vertical Transverse Isotropy (VTI) and Horizontal Transverse Isotropy (HTI), depending on the orientation of the symmetry axis.
