Improved Velocity Estimation and Imaging Using Multiple Wavefield Components - A North Sea Case Study, Brage Field

A case study was carried out over the Brage Field, where high fidelity velocity model was built to solve the complex velocity variations in the overburden. The shallow channel system was captured in the velocity model by the use of an integrated workflow combining refractions, multiples and reflections. Solving for the strong lateral velocity variations in the near surface resulted in significant movements of the target structures.
