Embodiments of the invention provide a method of processing marine seismic data, the data having been acquired using a “dense over/sparse under” streamer array having N over streamers disposed at a first depth and M under streamers disposed at a second depth greater than the first depth, where 0<M<N. The method comprises: a) processing seismic data for one of the over streamer target locations and seismic data for one of the under streamer target locations; b) processing seismic data for another of the over streamer target locations; and c) combining the result of (a) and the result of (b). The one of the over streamer target locations and the one of the under streamer target locations may lie in a vertical plane.
A method of processing marine seismic data, the data having been acquired at N over streamers disposed at a first depth and at M under streamers disposed at a second depth greater than the first depth, where 0<M<N, the method comprising:
A method of processing marine seismic data, the data having been acquired at N over streamers disposed at a first depth and at M under streamers disposed at a second depth greater than the first depth, where 0<M<N, the method comprising:
A method as claimed in claim 11 further comprising determining the up-going component of the seismic data for the second over streamer target location, and wherein (b) comprises combining the up-going component of the seismic data for the first over streamer target locations and the up-going component of the seismic data for the second over streamer target location.
An apparatus for processing seismic data, the data having been acquired at N over streamers disposed at a first depth and at M under streamers disposed at a second depth greater than the first depth, where 0<M<N, the apparatus comprising:
An apparatus for processing marine seismic data, the data having been acquired at N over streamers disposed at a first depth and at M under streamers disposed at a second depth greater than the first depth, where 0<M<N, the apparatus comprising:
