Technology Advances in Constructing High Resolution Velocity and Absorption Models over 35,000km2 in the North Sea

Summary Building very large scale depth velocity models for imaging and interpretation purposes is a challenging task that pushes the boundaries of software and hardware processing capabilities ( Gabrielli et al., 2016 ). Here we demonstrate a model build over what we believe is one of the largest areas ever published (~35,000 km2), highlighting the application of high-end technology, with an attention to detail and a delivery schedule that just a few years ago would have only been possible on a small scale survey. We also examine how integrating large amounts of carefully selected and pre-processed well and stratigraphic data benefits the model building process.
