“…In a 4D setting, minimizing these artefacts for each 3D seismic section independently does not necessarily lead to their automatic cancellation on the 4D difference section. For example 3D migration noise from base and monitor will not cancel out on 4D subtraction if the acquisition positioning is not well repeated (Poole and Lecerf, 2006). The purpose of 4D binning (with two vintages) is therefore to find, for each bin and each offset class, the most repeatable pair of traces between the base and monitor volumes.…”

4D binning is an important processing step to improve the repeatability of time-lapse (4D) data. Binning is a strategy for selecting those traces which are most similar between the timelapse vintages. With two vintages of 4D seismic data the trace similarity is easily obtained, for example, as the difference of the source and the receiver position of the corresponding traces. With more than two vintages, a "cascaded" approach has generally been used, whereby the vintages are binned pair-wise as in the two-vintage case, with each new vintage being binned relative to the previous ones. This does not necessarily yield an optimum solution for multi-vintage datasets and leaves open the debate about which vintage to pick as the reference. In this paper we introduce a simultaneous multi-vintage (SMV) 4D binning algorithm which obtains the best possible repeatability across all vintages and in each bin. We compare SMV 4D binning to cascaded 4D binning on a multi-vintage North Sea survey.

“…Data regularization plays a significant role in the migration process. Kirchhoff based methods depend upon the constructive interference of the migration operator at the reflector, and the destructive interference of the migration operator away from the reflector to build the image (Poole and Lecerf, 2006). Whilst weights can be used to ensure that the amplitude at the reflector is preserved when acquisition geometry is irregular, it is more difficult to ensure optimal destructive interference away from the reflector.…”

Wide Azimuth Towed Streamer (WATS) acquisition has already proved to be a key technique in improving seismic imaging, especially in complex areas such as sub-salt plays. In 2006, a WATS field experiment was conducted in a deep water area of the Gulf of Mexico. The main purpose was to challenge recently developed 3D processing algorithms and find the most suitable processing strategy for a wide azimuth dataset. The results indicate that a 3D shot based processing sequence is an effective solution that accommodates the effects related to the multi-pass acquisition method and realizes the full benefit of the recorded 3D wide azimuth wave field.
