Seismic receiver motion compensation

A method of compensating for seismic receiver motion in a marine seismic survey wherein a plurality of receivers is towed behind a seismic vessel, comprising:

• producing an acoustic energy wave at a seismic source;
• recording the reflection arrival time t2 of the acoustic energy wave at each of the receivers;
• determining the offset x between the source and each receiver;
• estimating the normal moveout velocity V for the acoustic energy;
• determining the velocity VB of the seismic vessel;
• and
• determining a corrected reflection arrival time t1 of the acoustic energy wave for each receiver by applying a time correction to the recorded reflection arrival time t2, the time correction being a function of the offset x, the normal moveout velocity V, and the velocity VB of the seismic vessel.

A method of compensating for seismic receiver motion in a marine seismic survey wherein a plurality of receivers is towed behind a seismic vessel, the receivers being hardwired to form receiver groups, comprising:

• producing an acoustic energy wave at a seismic source;
• determining the reflection arrival time t2 of the acoustic energy wave at the center of each receiver group;
• determining the offset x between the source and each receiver group center;
• estimating the normal moveout velocity V for the acoustic energy;
• determining the velocity VB of the seismic vessel;
• and
• determining a corrected reflection arrival time t1 of the acoustic energy wave for each receiver group center by applying a time correction to the recorded reflection arrival time t2, the time correction being a function of the offset x, the normal moveout velocity V, and the velocity VB of the seismic vessel.
