NOISE MITIGATION FOR SEISMIC SURVEY MULTI-DATASETS

摘要

Techniques for mitigating noise in seismic data including a plurality of measured values of a plurality of components are disclosed. The techniques use relations among the plurality of components. The techniques are adapted to parallel processing computer hardware. The techniques can include obtaining seismic data including a plurality of values of a plurality of components, estimating a plurality of noise spectra values, the respective noise spectra values representing a noise content in a respective component of the plurality of components, computing a plurality of dynamic weights, the respective dynamic weights being a function of a respective one of the noise spectra values, generating a vector autoregressive model using the plurality of dynamic weights and the plurality of components, filtering the seismic data with the vector autoregressive model, such that noise-mitigated seismic data is produced, and providing the noise-mitigated seismic data.
