Abstract

Systems and methods for direct arrival estimation for marine seismic data are provided. A computer-implemented method for estimating direct-arrival energy in seismic data acquired in a marine environment, the method including: executing, by one or more processors, operations on seismic data that contain up-going and down-going wavefields in which direct-arrival information is not properly or completely recorded, processing the seismic data using a computer-based wavefield-analysis technique to identify water-layer reverberation events within the up-going and down-going wavefields, leveraging, through computer-implemented analysis, stable relationships among water-layer reverberations, computing, by the processors, an estimated direct-arrival signal based on the identified relationships to compensate for missing or improperly recorded direct-arrival information, and producing, using the processors, a direct-arrival estimate configured for use in subsequent seismic-processing operations.
