Abstract

Summary

Triple-source, continuous-recording acquisition is used to acquire a modern, high density 3D survey across the Senja Ridge and the surrounding salt provinces of the Tromsø and Sørvenstsnaget basins, in the Western margin of the Norwegian Barents Sea.

A robust imaging workflow is developed and presented, combining deblending technology with extensive demultiple methodology to precondition the data for velocity model building, utilising Full Waveform Inversion and high-resolution image guided tomography.

The final migrated image delivers a significant uplift in imaging across the area, with the advanced velocity model building techniques adding confidence to the positioning of events both within the Senja Ridge and the surrounding salt basins.
