| Abstract | Summary Removing the receiver ghost before migration provides better low and high frequency response as well as a higher signal-to-noise ratio for preprocessing steps such as multiple suppression and velocity analysis. We propose a bootstrap approach that self-determines its own parameters for receiver deghosting. The recorded data in shot domain are first used to create mirror data through a 1D ray tracing based normal moveout correction method; then both the recorded and mirror data are used to jointly invert for the receiver-ghost-free data. We demonstrate with both synthetics and real data that our deghosting method can, in many situations, reliably remove the receiver ghost for marine towed streamer data in the premigration stage. Here, this technique is used to partially improve the bandwidth of conventional streamer data but for optimal broadband seismic, a full broadband system (like BroadSeis) is necessary. |
