The Senja Ridge is a structurally complex high located in the western margin of the Norwegian Barents Sea. A two stage velocity model building approach is implemented, utilising diving wave FWI and high resolution image guided tomography. Shallow gas clouds and shallow channels are resolved with the FWI updates, deeper structures including basement horsts within the Senja Ridge and the flanks of salt diapirs are solved with the tomographic updates.
