摘要： The present disclosure includes methods for seismic monitoring of a subterranean formation. The method includes receiving resulting signals emanating from the subterranean formation, wherein the resulting signals are caused, at least in part, by incident signals emitted from a plurality of seismic sources located above the subsurface formation and wherein the resulting signals are received for a predetermined emission length of time. The method further includes dividing at least a part of the resulting signals into a plurality of sub-samples. The method includes, for one or more of the sub-samples, determining a frequency content of the sub-sample and assigning a weight to or more components of the frequency content of the sub-sample to produce a weighted frequency content of the sub-sample, wherein the assigned weight is based, at least in part, on an estimate of the amount of noise present in the frequency content of the sub-sample. The method further includes combining the weighted frequency contents of the sub-samples to produce a weighted sample. The method further includes determining one or more properties of the subsurface formation based, at least in part, on the weighted sample.
