Geophysical contractor providing gravity and magnetic services and products to the international oil and mining industry. Offices in Leeds and Houston.

Special processing for traditional marine data using "Partial Synergetic Imaging-", or PSI-criterion.

A novel approach to Reflector Geometry Reconstruction: proper assimilation of prestacked multioffset traveltimes, macro-model-independent seismic reflection (depth) imaging.

Elimination of intrabed multiples: SoSI-inversion. Site shows a novel approach to the comprehensive elimination of multiples -including intrabed ones. It is based on recursive representation of Born series inversion and realized in a form of a fast routine, capable of running in a fully automatic mode.
