Summary In time-lapse processing, independent regularization of each vintage is the typical approach. This disregards any geometrical limitations imposed by different surveys. Here we recast the regularization process as a minimization problem with m

Dynamic reservoir monitoring using seismic data is now a common practice, but when BP North Sea first embarked on this in 1992 using streamer data over Magnus streamer, it was very much stepping into the unknown, with a hope of meeting our pioneering

Ocean bottom seismic (OBC) data has been shown to give significant uplift over traditional streamer data. Independent Simultaneous Shooting (ISS) has been shown to provide significant efficiency improvements with no detrimental effect on data quality

In this paper, we show the application of Tau-P deconvolution in wavelet domain, and deconstrate the benefit of this methodology with improved multiples and noise attenuation from a couple of North Sea OBC surveys. We start by decomposing the seismic

HTI media yield azimuth-dependent reflectivities which may relate to fracture parameters. However, azimuthal information in seismic data is susceptible to bias resulting from acquisition or processing. This paper describes a method which analyses azi

In the time-lapse processing paradigm, a method has recently been proposed to simultaneously adapt multiple models in such a way that 4D differences are optimized (Zabihi et al., 2012). We build on this idea in developing a seismic processing workflo

In conventional processing of ocean-bottom cable (OBC) seismic, after separation of upgoing and downgoing wavefields, the upgoing data are processed while downgoing data are discarded. However, the illumination of the shallow section is much better f

Subsalt imaging is seen as one of the most difficult imaging challenges in seismic processing. Although that is a discussion in itself, no one will question the fact that processing seismic for subsalt exploration is very complicated due to the struc
