Surface-Related Multiple Elimination For Depth-Varying Streamer

摘要

Techniques are described for predicting surface-related multiples from measurements performed at varying depths. One or more operations, such as wavefield decompositions and/or extrapolations, may be performed on scattered wavefield data obtained by underwater sensors at different underwater depths to determine one or more surface-related multiple wavefield contributions at a selected depth or at the different underwater depths where the scattered wavefield data is collected from measurements.
