The 2018 Tablelands GeoStreamer seismic survey was acquired in partnership with Nalcor, PGS, and TGS in the Orphan Basin, offshore Canada. The partnership pioneered a proof of concept project over a deep-water 500 km2 survey. The project demonstrated the benefits of building a Full Wavefield Inversion (FWI) driven velocity model using dual-sensor data. This paper presents the FWI velocity model building workflow, which produced a high-resolution and geologically consistent velocity model. The model was later used in Kirchhoff migration, Least-Square Wave-Equation migration, and for quantitative interpretation purposes.

Depth migration techniques have been widely used in areas with strong lateral velocity variation. Though very robust, these methods suffer from acquisition and propagation effects that limit resolution and impact amplitudes of seismic images. Least-Squares Migration (LSM) is becoming a standard in areas with complex geology. It compensates for acquisition limitations and variable illumination and results in more reliable amplitude information with higher resolution. In this case study, data-domain LSM is applied to deep-water seismic data from offshore Canada targeting vertical resolution and fault definition improvements.
