METHODS AND SYSTEMS FOR INTERPOLATION OF MULTI-COMPONENT SEISMIC DATA COLLECTED IN A MARINE ENVIRONMENT

摘要

Computational systems and methods for interpolating a pressure wavefield based on pressure wavefield and particle motion wavefield data are disclosed. The pressure and particle motion wavefields are sampled at a sample rate that is less than a lower bound for sample rates typically used to interpolate the pressure wavefield from the pressure wavefield samples alone. The particle motion wavefield can an acceleration wavefield or a time derivative of a velocity wavefield.

1. A method for interpolating seismic data obtained from a marine seismic survey using a programmable computer programmed to at least perform the operations of:
recording pressure wavefield samples of pressure wavefield measured with pressure sensor at a sample rate; recording particle motion wavefield samples of particle motion wavefield measured with particle motion sensor sampled at the sample rate; and interpolating a pressure wavefield in the time domain based on the pressure wavefield samples and the particle motion wavefield samples, wherein the sample rate is less than a lower bound for sample rates used to interpolate the pressure wavefield from the pressure wavefield samples alone.
