SEISMIC NOISE REMOVAL |
| 摘要 |
A method for removing seismic noise from an input seismic trace. The method may receive the input seismic trace. The method may receive one or more noise references for the input seismic trace. The method may receive one or more filters corresponding to the noise references. The method may apply a nonlinear function to the input seismic trace and to the one or more noise references to produce respective output signals for the input seismic trace and for the one or more noise references. The nonlinear function may be capable of determining higher-order statistics. The method may update the filters based on increasing one or more information attributes of the output signals to a predetermined threshold. The method may then filter noise corresponding to the noise references. |

1. A method for removing multiples from an input seismic trace, comprising:
receiving the input seismic trace; receiving one or more multiple predictions for the input seismic trace; receiving one or more filters corresponding to the multiple predictions; applying a nonlinear function to the input seismic trace and to the one or more multiple predictions to produce respective output signals for the input seismic trace and to the one or more multiple predictions, wherein the nonlinear function is capable of determining higher-order statistics; updating the filters based on increasing one or more information attributes of the output signals to a predetermined threshold; and filtering multiples corresponding to the multiple predictions from the input seismic trace using the updated filters. |
