Coherent noise attenuation using statistical methods
First Claim
1. A system for attenuating coherent noise from seismic data, comprising:
- one or more sensors configured to sense waves generated by a seismic source; and
a coherent noise attenuation module comprising a processor and memory, the coherent noise attenuation module communicably coupled to the one or more sensors and operable to;
receive a plurality of traces of seismic data from the one or more sensors;
apply a first transformation to the plurality of traces of seismic data;
identify one or more outlier waveforms in the transformed traces;
attenuate the identified outlier waveforms; and
apply a second transformation to the plurality of transformed traces,the second transformation being an inverse of the first transformation.

Abstract
A system for attenuating coherent noise from seismic data comprises one or more sensors configured to sense waves generated by a seismic source and a coherent noise attenuation module communicably coupled to the one or more sensors and comprising a processor and memory. The coherent noise attenuation module is operable to receive a plurality of traces of seismic data from the one or more sensors and apply a first transformation to the plurality of traces, identify one or more outlier waveforms in the transformed traces, attenuate the identified outlier waveforms, and apply a second transformation to the plurality of traces that is the inverse of the first transformation.
