摘要： A computationally economical method for applying multi-dimensional multiple-reflection attenuation to a marine seismic-signal data set comprised of a plurality of common shot gathers that have surface-multiple wavefields embedded therein. The multi-dimensional data are assumed to have been gathered from a plurality of parallel 2-D lines of survey. From every nth reference line, where n is a small number greater than 2, a common shot gather is selected. For every so-selected common shot gather, a reference surface-multiple wavefield is predicted as a function of offset and travel time with the aid of any well-known multiple attenuation routine, using a wavelet having fixed attributes in terms of amplitude, phase and frequency. A common shot gather is chosen from among the plurality of common shot gathers. The predicted surface-multiple wavefield nearest to the chosen common shot gather is adaptively filtered to match the predicted surface-multiple wavefield to the surface-multiple wavefield embedded in the chosen common shot gather. The matched predicted surface multiple wavefield is subtracted from the embedded surface multiple wavefield to provide a multiple-free common shot gather.

摘要： Method for attenuating surface multiple reflections in dual-wavefield seismic data. In one implementation, the method may include: (a) performing wavefield separation on dual-wavefield seismic data to separate events in the seismic data into data sets according to ghost characteristics; (b) applying a multidimensional Surface-Related Multiple Elimination (SRME) to two or more of the data sets to yield an SRME result in a manner that retains surface reflection information affecting surface multiple reflections; and (c) repeating step (b) one or more times.

摘要： Traveltimes of multiply reflected seismic events in a seismic profile or a model are determined from traveltimes for primary events. The traveltimes for the primary events may be obtained by ray tracing through a velocity model of the subsurface of by picking traveltimes from primary reflection horizons present in an actual seismic data set. The traveltimes for the primary events define a traveltime table for various combinations of source and receiver locations. The traveltime for a multiple corresponding to specified source and receiver positions is then determined by summing the traveltimes for primary events from the source to an interim point and from the interim point to the receiver: the correct location of the interim point corresponding to an actual multiple reflection raypath from the source to the receiver is the one that, according to Fermat's principle, has the minimum value for the sum. This method is applicable to all primary events, so that subsurface multiples as well as water bottom multiples can be determined. The method may also be used for determining traveltimes for higher order multiples.
