Prime is a software for processing of 2D/3D/4D/3C/4C onshore and offshore wide-azimuth or narrow-azimuth complex seismic data. The software includes solutions for the heterogeneous upper part compensation, salt domes, strongly dislocated tectonics, shallow and transit zones, wave field transformation, demultiple, deghosting and much more technologies. Prime has been developed as a link between processing and interpretation and provides advanced technologies for interpretative seismic data processing. These technologies give the possibilities to account for a priori information, process data in depth domain and operate with interval velocities starting from the first stages of a project.
