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...

The Viking Graben is a mature exploration area on the Norwegian Continental Shelf that still suffers from illumination and resolution challenges that reprocessing alone cannot solve. In the following...

Seismic amplitudes can be biased by uneven illumination in the presence of a complex overburden. Iterative Least Squares Migration (LSM) can reduce the amplitude bias and improve the resolution of...

Full integrity PSDM data from the 2019 PGS GEoStreamer X acquisition program in the Lille Prinsen area of the Viking Graben is now available. It delivers on all its promises to provide the highest...

During the last decades, broadband seismic surveys became more prevalent and for several years this has also been used for time-lapse seismic monitoring of hydrocarbon producing fields or CO2 storage...

This work describes a method for computing the full acoustic seismic wavefield using a new two-way equation parameterized by vector reflectivity and velocity. This method is contrasted with full...

I discuss the important similarities and distinctions between RTM (Reverse Time Migration), LS-RTM and FWI, and also relate their fundamental reliance upon back-projection to Deep Neural Network...

Andrew Long attempts to explain FWI in accessible terms by presenting the critical steps for the methodology to yield useful results, and refers to some common ambitions of the many industry and...

The authors describe an integrated workflow where full waveform inversion velocity data, well log data, seismic stratigraphy, basin analysis, and rock physics modelling are combined to produce 3D...

When integrated with the PGS MultiClient seismic data library, rockAVO provides a reliable interactive toolset to understand seismic responses and their relation to geological properties.
