Speaker

Simon Baldock, Chief Geophysicist, TGS UK

Simon Baldock has over 30 years’ experience of seismic data processing. He joined CGG in London in 1988 and over the next 17 years he held positions in their London and Houston offices. While at TGS he worked extensively on denoise and demultiple for marine data, as well as OBN, 4D and some land data processing. In 2006 Simon joined TGS in Houston. With TGS he has held a range of senior technical and management roles in the both the UK and the US and worked with NAZ, WAZ and OBN data. He returned to the UK in 2017, where he is currently Chief Geophysicist, Data Imaging, for the Eastern Hemisphere, based in TGS’ Woking office.

Abstract

Efficient acquisition of large-scale OBN surveys is now a reality, delivering data that are long-offset, azimuth-rich and high-density. These data provide an opportunity to apply advanced preprocessing and model building techniques to create high resolution velocity models that, in turn, generate stunning images of the subsurface. From high-resolution modelling of cemented sand structures in the North Sea to imaging of deep pre-salt structures in the Gulf of Mexico. This talk, from one of the leading providers of regional OBN data, will demonstrate the potential of OBN data. The key technologies including preprocessing (deblending, PZ calibration and demultiple) and depth imaging, focussing on the advantages of dynamic matching FWI (DM-FWI), will be examined alongside how they vary from shallow to deep water. The view from the seabed has never been richer nor more exciting.
