摘要： Methods (600, 1100) and devices (1200) for seismic data processing attenuate noise by replacing an attribute value v(i) of a selected data point (700) i with a weighted average v̂(i) of attribute values of data points j from a window (710) that includes the selected data point i. The contribution to the weighted average of an attribute value v(j) corresponding to a data point j depends on how similar attribute values in the neighborhood N j of the data point j are to attribute values in the neighborhood N i of the selected data point i.

摘要： Controller and method for determining a driving signal of a vibro-acoustic source element that is configured to generate acoustic waves in water. The method includes estimating at least one physical constraint of the vibro-acoustic source element; modeling a ghost function determined by a surface of the water; setting a target energy spectrum density to be emitted by the vibro-acoustic source element during the driving signal; and determining the driving signal in a controller based on at least one physical constraint, the ghost function, and the target energy spectrum density.

摘要： There is a method of seismic data processing that includes receiving (1600) seismic data that includes a set of seismic traces, each trace including a signal recorded by a sensor after having been propagated in a subsurface area; migrating (1602) the seismic data according to a first velocity model; picking (1604) from the timemigrated seismic data one or more events corresponding to one or more subsurface reflectors so as to obtain a set of facets locally approximating the event; kinematic demigrating (1606) the picked set of facets so as to obtain simplified seismic data that includes the set of facets and a set of attributes associated with the set of facets; migrating (1608) the set of facets based on a second velocity model; and updating (1610) the initial velocity model based on an alignment of migrated points within the set of facets.

摘要： System and method for actuating first and second marine acoustic sources in a firing sequence, the firing sequence including at least a first actuation of the first source followed by a first actuation of the second source followed by a second actuation of the first source and a second actuation of the second source. The method includes towing the first source at a depth in water substantially equal to a depth of the second source; establishing a series of reference time instants; actuating the first source with a variable first time delay relative to the series of reference time instants; and actuating the second source with a variable second time delay relative to the series of reference time instants such that time intervals between consecutive activations of the first and second sources are also variable.

摘要： Device, medium and method for de-blending seismic data. The method for de-blending seismic data associated with a subsurface of the earth includes receiving initial seismic traces (600) recorded by plural sources; de-blending, in a processor (1302), the initial seismic traces (600) to generate de-blended seismic traces (818, 820); and generating an image of the subsurface based on the de-blended seismic traces (818, 820). The initial seismic traces (600) include uncontaminated portions corresponding to time intervals substantially free from cross-talk from other sources, and the uncontaminated portions are used to remove cross-talk noise on other initial seismic traces.

摘要： 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.
