Central Graben - Norway

PGS16008CGR 3D GeoStreamer

Ultra-high resolution to unlock hidden potential
Website Map for Survey PGS16008CGR
Covering the Krabbe field and discoveries at the eastern flank of the Central Graben, this survey offers full 3D AVO-compliance in this underexplored area to facilitate exploration for stratigraphic and structural traps.
Most fields and discoveries within PGS16008 have their reservoirs in Upper Jurassic sandstones. Potential is also seen in the Paleocene and Permian sandstones as well as in the chalk.
With improved imaging of stratigraphic traps, subtle structural traps in the shallow and clear resolution of the structures in the deep, GeoStreamer enables you to unlock the hidden potential of this area.
