Viking Graben

Find new fields in a mature area that stretches from the Utsira High to the Stord Basin. This is home to some significant finds, such as Balder and Johan Sverdrup. GeoStreamer PURE Viking Graben offers ~18 000 sq. km of depth data and provides the structural overview and reservoir details you need to unlock new leads and opportunities in this region.

The Viking Graben is home to key discoveries such as Storklakken, Ivar Aasen, Johan Sverdrup, Gina Krog, and Grevling.

 Key Benefits

  • Explore the regional structure, identify leads and develop prospects
  • Excellent depth data with seamless velocity model
  • Improved imaging of the Jurassic and new insights in Alvheim
  • ~18 000 sq. km of GeoStreamer data

Geology

Late Jurassic rifting led to the formation of numerous horsts and rotated fault blocks along the margins of the graben. This area is known for its high-quality hydrocarbon reservoirs.  A variety of play types exist here, such as Paleocene deep marine sands and injected sands at Hermod, Heimdal, and Ty formations. Late Jurassic shallow and deep marine sands are present in the Hugin formation and intra-Heather and Draupne formations, as well as Early and Middle Jurassic shallow marine to coastal/deltaic sands.

Imaging

Our tailored workflow for GeoStreamer® data overcomes many of the imaging challenges related to this varied geological setting such as the resolution of shallow channels, injectites, and Vbrites.The results offer new insight and reveal new opportunities.

Complete Wavefield Imaging has significantly improved delineation and imaging of fault blocks, with a combination of full waveform inversion (FWI) and separated wavefield imaging (SWIM) for quality control, plus TTI velocity model building and final TTI Q-Kirchhoff depth migration.

New insights include the greater Alvheim reservoir with stratigraphic pinch-outs, improved imaging of the Jurassic source rock and individual Jurassic fluvial-deltaic to shallow marine sandstones and sub-marine fans of Paleocene age, and clearer rendering of the intra-Jurassic and Paleocene mudstones.
