The promise of fully automatic full-waveform inversion (FWI) — a (seismic) data-driven velocity model building process — has proven elusive in complex geologic settings, with impactful examples using field data unavailable until recently. In 2015

The use of time-lapse (4D) seismic at BP now has a track record stretching back more than 20 years. In the North Sea, reservoir types such as Tertiary turbidites and Cretaceous chalks produced clear 4D signals, and uptake increased rapidly in the lat

To realize the vision of automatic velocity model building with full-waveform inversion, a paradigm shift in the way seismic data are acquired is necessary. In December 2017 – January 2018 BP acquired 1000km of source lines over the deepwater sub-s

Imaging and characterizing time-lapse changes in reservoir properties rely on accurate estimation of the corresponding time shifts and amplitude changes. We evaluated the accuracy of competing time-shift extraction algorithms — cross correlation, n

A methodology has been developed for quantitative prediction of shallow-hazard zones based on 3D high-resolution (3DHR) seismic and shallow-log data. The main goal of the integrated workflow is to produce an optimal structural image, conduct an AVO f

The available seismic imaging methods are challenged by the presence of massive and complicated salt bodies. This complex overburden affects seismic wave propagation in many ways including attenuation. As a consequence, the amplitude and frequency of
