Abstract: A survey plan is designed and potentially adjusted so that seismic data acquired during the survey include inline and cross-line seismic data irregularities suitable for compressive sensing reconstruction. At least one of the inline and cross-line irregularities is dynamic and may be due to source, vessel(s) and/or streamer steering.

Abstract: 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.
