3D GPU modelling and future work

The next step in this concept is to extend the modelling to 3D. Thirty-two VSP shots are in the process of being modelled, with the entire surface wavefield saved every several time steps (such that the survey time sampling is 4ms.) From these densely sampled wavefields both continuous linear towed streamer and continuous coil shot streamer surveys will be modelled. These data can then be migrated (reverse time) and their images and 3D angle gathers analysed to see if better offset sampling per azimuth is observed, and if the survey type changes are noticeable in the final images.
