    摘要: During seismic data acquisition the seismic sources and/or seismic receivers are deployed according to an irregular arrangement departing in a predetermined manner from repetitive spatial patterns formed by or within groups of adjacent among the seismic sources or adjacent among the receivers. Additionally or alternatively, source activation moments of the sources within a series of source firing time intervals are determined using Golomb ruler sequences or a non-linear inversion.

    摘要: Systems and methods are provided for de-noising seismic data recorded by seismic receivers. A first portion of the seismic data having a first signal-to-noise ratio (SNR) to is processed to generate a de -noising operator or function. The de-noising operator is applied to a second portion of seismic data having a second SNR to remove noise from the second portion of the seismic data, where the first SNR is greater than the second SNR.
