In this E-Lecture Sjoerd de Ridder provides an introduction to passive seismic interferometry using surface waves with applications to reservoir geophysics. First, he addresses the nature of seismic noise typically recorded at low frequencies by marine seismic arrays. Then, he explaines the basic principle of passive seismic interferometry and shows virtual seismic sources obtained by cross-correlating microseism noise. Lastly, he demonstrates example applications of imaging anisotropy and time-lapse velocity changes using virtual seismic sources.
