A 500 km2 proof-of-concept project in deep-water Canada demonstrated the benefits of combining recently acquired multisensor streamer data and new imaging technologies to produce a detailed velocity model and a robust seismic image that can minimize uncertainties prior to drilling. We describe the full waveform inversion (FWI) and leastsquares migration (LSM) workflow that not only resulted in high-resolution seismic sections, with improved fault definition and signal to noise (S/N) ratio in the Cretaceous and Jurassic sections, but also produced AVO-compliant image gathers that can benefit quantitative interpretation.
