PROCESS FOR SEPARATING DATA RECORDED DURING A CONTINUOUS DATA ACQUISITION SEISMIC SURVEY

摘要

Method for separating signals recorded by a seismic receiver and generated with at least two vibratory seismic sources driven with no listening time. The method includes receiving seismic data that includes data d recorded by the seismic receiver and data related to the first and second vibratory seismic sources; computing a source separation matrix based on the data related to the first and second vibratory seismic sources; calculating first and second earth impulse responses HA and HB corresponding to the two vibratory seismic sources, respectively, based on the data d recorded by the seismic receiver, the data related to the two vibratory seismic sources and the source separation matrix; and separating the signals recorded by the seismic receiver based on the first and second earth impulse responses HA and HB such that signals the two vibratory seismic sources are disentangled.

1. A method for separating signals recorded by a seismic receiver and generated with at least first and second vibratory seismic sources, the method comprising:
receiving seismic data that includes data d recorded by the seismic receiver and data related to the first and second vibratory seismic sources, wherein the first and second vibratory sources are driven simultaneously and continuously with no listening time; computing in a computing device a source separation matrix based on the data related to the first and second vibratory seismic sources; calculating first and second earth impulse responses HA and HB corresponding to the first and second vibratory seismic sources, respectively; and separating the signals recorded by the seismic receiver based on the first and second earth impulse responses HA and HB such that signals originating from the first vibratory seismic source are disentangled from signals originating from the second vibratory seismic source.
