Process for separating data recorded during a continuous data acquisition seismic survey

A computing device for separating signals recorded by a seismic receiver and generated with at least first and second vibratory seismic sources, the computing device comprising:

• an interface for 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 for generating the data d;
• and
• a processing unit connected to the interface and configured to,
• compute a source separation matrix based on the data related to the first and second vibratory seismic sources;
• calculate first and second earth impulse responses HA and HB corresponding to the first and second vibratory seismic sources, respectively;
• and
• separate 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.

A non-transitory computer readable medium including computer executable instructions, wherein the instructions, when executed by a processor, implement a method for separating signals recorded by a seismic receiver and generated with at least first and second vibratory seismic sources, the instructions 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.
