    摘要: The presently disclosed technique includes a method for use in a marine survey comprising randomizing the distribution of receivers and sources during a coil shoot acquisition. The randomizing can be implemented in a number of ways. For example, in one embodiment, randomizing the distribution includes randomizing the positions of the circle centers defining the sail lines. This may be implemented by, for example, distributing the same number of circle centers as would be used in a non-random sampling in a uniform random distribution. In another embodiment, randomizing the distribution includes permitting the streamers in which the receivers are allowed to drift while controlling crossline streamer separation. Other embodiments may combine these approaches or utilize still other approaches.

    摘要: A method for estimating internal multiples in seismic data. The method includes selecting a subset from a set of regularly sampled seismic data based on a low-discrepancy point set. The method may then include integrating one or more depth integrals of the inverse-scattering internal multiple prediction (ISIMP) algorithm over each data point in the subset. After integrating the depth integrals, the method may then include integrating a function of the integrated depth integrals using a quasi-Monte Carlo (QMC) integration over the subset, thereby generating an estimate of the internal multiples.
