Abstract
The technique about the surface consistent correction is used widely in seismic data processing. And the hypothesis about the surface consistence is the default condition. However, some receiver responses usually violate the assumption due to the receivers are mounted at the same locations several times, which will make the receiver factors of the surface consistent correction more than one value. These receiver factors include the polarization of the horizontal receiver component, which extends the conventional surface consistent technique. Through analysing, the paper proposed that the receiver condition of a Common Attitude Gather (CAG), a subset extracted from a Common Receiver Gather (CRG), can well satisfies the surface consistence. The actual examples show that the method for estimating and correcting the orientation of the horizontal receiver based on the CAG, substituted for the CRG, is effective and feasible in 3D3C seismic exploration industry.
