Seismic Data

Multiples, often viewed as noise in seismic data, can enhance shallow subsurface imaging when used strategically. In Exploring the Benefits and Pitfalls of Using Multiples in Imaging, Gordon Poole and Milad Farshad discuss how free-surface multiples can improve shallow illumination in challenging acquisition setups like wide-tow streamer and OBN designs. By re-injecting recorded data as secondary sources, their method addresses issues like heavy striping and limited near-offset recordings, reducing reliance on extensive site-specific surveys.
