Interferometry extracts valuable phase information from seismic

For well over 70 years explorers have used seismic survey techniques and seismic wave amplitude interpretation to discover oil and gas.In that time they have relied solely on the measurement of seismic wave amplitude and have ignored the key parameter of seismic wave phase. In fact, they have chosen to remove seismic phase information from interpretation, opting to create and use zero-phase data.Now seismic interferometry, a technology that creates and uses phase information about reflected and refracted seismic waves, has the potential to revolutionize exploration geophysics by creating a new dimension of analyzing the key parameter of phase. Use of phase data has led to the field testin...
