Ocean-bottom hydrophone and geophone coupling

ABSTRACT

We compare two methods for combining hydrophone and geophone components for an ocean-bottom seismic experiment to eliminate the receiver ghosts associated with this type of seismic acquisition. One approach is in the time domain, the other in the frequency domain. Both approaches are compared with the 2D OBS data over the Mahogany field in the Gulf of Mexico. The receiver ghosts are eliminated more efficiently with the frequency domain method, because this method combines the data in two different steps: i) calibration, and ii) deghosting.
