ABSTRACT:
Information about coupling of a seismic receiver is obtained from a power spectrum for a record acquired at a seismic receiver. In one method, the power spectrum for the record is compared with a reference power spectrum, which may be known a priori or which may be determined from the power spectra of records acquired by a group of receivers. In an alternative method, one receiver of a group of receivers is designated as a reference receiver, and the power spectra of records acquired by other receivers in the group are compared with a power spectrum for the reference receiver. The obtained information about the coupling of a receiver may be used to determine a coupling correction operator for the receiver, and this operator can be applied to seismic data acquired by the receiver to correct for the effects of imperfect coupling of the receiver.
