Kirchhoff methods are widely recognized as one of the most comprehensive and flexible methods of imaging prestack 3-D seismic data. ZTK is Z-Terra’s implementation of three-dimensional Kirchhoff migration in depth and in time. ZTK images seismic data by approximately solving the wave equation with a ...

Obtaining high quality images of subsurface structures requires an accurate velocity model. Migration Velocity Analysis (MVA) improves the velocity model associated with a survey in order to create an accurate image of subsurface structures. After seismic data has been migrated through its current i ...

Diffraction Imaging (DI) is a novel seismic imaging technique for focusing diffractions in order to produce super-resolution images of diffractors unattainable by conventional means. Seismic diffractors are small scale scattering subsurface elements such as small faults, fault edges, pinch-outs, sal ...
