“…The seismic data were acquired with a 10 km-long streamer in the years 2013 to 2014 and re-processed in 2020. Re-processing resulted in higher signal to noise ratio, improved event continuity and more reliable images from the deeper Cretaceous and Jurassic sedimentary sequences in the Basin (Hardy et al 2021). The PSDM was performed following high-quality signal processing, using velocities obtained after full waveform inversion (FWI) and six iterations of reflection travel-time tomography incorporating an anisotropic model to best tie regional well depths.…”
