Device and method for multi-shot wavefield reconstruction

A computing device for reconstructing seismic data, the computing device comprising:

• an input/output interface for
• receiving an input seismic data set d related to plural shots emitted by one or more seismic sources (S), wherein the input seismic data set d is indicative of seismic wave paths from the one or more seismic source (S) to receivers,
• receiving a positional data set dp relating to recording locations of the receivers that recorded the input seismic data set d, and
• receiving a receiver target location;
• and
• a processor connected to the input/output interface and configured to,
• calculate an adjusted receiver location based on (i) the positional data set dp and (ii) the receiver target location, wherein the adjusted receiver location is a receiver location from the positional data set dp that is closest to or substantially coincides to the receiver target location,
• calculate reconstructed seismic data dr at the adjusted receiver location using the input seismic data set d and the positional data set dp, and
• correct the seismic wave paths from the one or more seismic sources (S) to the receivers based on the reconstructed seismic data dr.

A non-transitory computer readable medium including computer executable instructions, wherein the instructions, when executed by a processor, implement a method for reconstructing seismic data, the method comprising:

• receiving at a computing device an input seismic data set d related to plural shots emitted by one or more seismic sources (S), wherein the input seismic data set d is indicative of seismic wave paths from the one or more seismic source (S) to receivers;
• receiving at the computing device a positional data set dp relating to recording locations of the receivers that recorded the input seismic data set d;
• receiving at the computing device a receiver target location;
• calculating, with the computing device, an adjusted receiver location based on (i) the positional data set dp and (ii) the receiver target location, wherein the adjusted receiver is a receiver location from the positional data set dp that is closest to or substantially coincides to the receiver target location;
• calculating, with the computing device, reconstructed seismic data dr at the adjusted receiver location using the input seismic data set d and the positional data set dp;
• and
• correcting the seismic wave paths from the one or more seismic sources (S) to the receivers based on the reconstructed seismic data dr.
