Abstract: Methods for determining a seismic wave's propagation velocity in water for monitor seismic data of a 4D data set analyze a relationship between seafloor time-shifts and source-receiver offsets. The time-shifts are differences of normal move out corrected seafloor source-receiver travel times for pairs of traces. Each pair includes a base trace extracted from base seismic data of the 4D data set and a monitor trace extracted from the monitor seismic data, the traces corresponding to the same seafloor bin and having the same source-receiver offset.

Abstract: A non-blended dataset related to a same surveyed area as a blended dataset is used to deblend the blended dataset. The non-blended dataset may be used to calculate a model dataset emulating the blended dataset, or may be transformed in a model domain and used to derive sparseness weights, model domain masking, scaling or shaping functions used to deblend the blended dataset.

Abstract: Systems and method for improved analysis of seismic data are provided. The method includes obtaining seismic data including a plurality of vintages, and generating a plurality of attribute matrices based on the seismic data. The method further includes computing a centrality measure for each vintage of the plurality of vintages using the plurality of attribute matrices, and selecting, from the plurality of vintages, a vintage with the highest centrality measure as a reference vintage. Additionally, the method includes determining an oulier from the plurality of vintages based on correlating each of the plurality of vintages with the reference vintage.

Abstract: A method for calculating time-strains for two seismic data sets resulting from seismic exploration of the same subsurface structure uses selected subsets of data from the two seismic data sets to calculate time-shifts for each trace. A smooth function is fitted along each trace based on the calculated time-shifts a time derivative is applied to the smooth function to obtain time-strains along each trace.
