Abstract
Modern 3D seismic offers the opportunity to generate new hydrocarbon prospects at the heart of the Norwegian Barents Sea, in a strategic position for existing infrastructure and potential future development.

The 3D seismic consists of 3,600 km2, acquired in 2012 and 2017, which has been processed with a modern broadband sequence.
New prospects generated in the Norsel High
Following the drilling of the first well on the Norsel High (7226/11-01) in the 1980s, this area has been overlooked for more than two decades, despite the discovery of gas in the Havert Formation. Over twenty years later, wells 7225/03-01 and -02 found multiple gas zones at the top of the Norvarg Dome, in the Stø, Snadd and Kobbe Formations (Figure 1). The drilling campaigns did not resolve the full extent of these accumulations. Discoveries in the surrounding area include the Ververis and Arenaria wells, where Ververis proved gas in Middle Triassic sandstone, although the gas-water contact was never found.
