Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for generating receiver deghosted output according to a receiver deghosting model. In one aspect, a method includes receiving an offshore seismic dataset of a surveyed subsurface that includes a seismic wavefield and is collected by receivers that comprise a streamer that is deployed relative to a water surface; determining an initial plane value for the water surface reflectivity and an initial location value for a position of the streamer; generating a receiver deghosting model by backward and forward propagating the seismic wavefield at the water surface to streamer locations, the receiver deghosting model including tuning parameters; adjusting the tuning parameters according to an adaptive target residue and an inversion target residue; generating receiver deghosted output according to the tuned receiver deghosting model; and determining a productivity of the surveyed subsurface based on the receiver deghosted output.
