Patent attributes
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.
