GeoStreamer PURE Viking Graben offers ~19 000 sq. km of depth data and provides the structural overview and reservoir details you need to unlock new opportunities in this region.
Find new fields in a mature area that stretches from the Ling Depression to the Fensal Sub-basin and includes the Beryl Embayment. This is home to some significant production hubs as Balder-Ringhorne, Alvheim, Grane and Johan Sverdrup.
Other key discoveries covered by the PURE Viking Graben are Ivar Aasen, Solveig, Bøyla, Frosk, Beryl, Alvheim and Heimdal.
- Explore the regional structure, identify leads and develop prospects
- Excellent PSDM with continuous velocity models
- Improved imaging of the Jurassic and new insights in Alvheim
- ~19 000 sq. km of GeoStreamer data
Late Jurassic rifting led to the formation of numerous horsts and rotated fault blocks along the margins of the graben. The Viking Graben is known for its prolific source rocks and high-quality reservoirs providing a variety of play types such as Paleocene deep marine fan deposits of the Hermod, Heimdal, and Ty formations, or reworked/remobilized Hermod or Heimdal Fm sands injected into shallower stratigraphy. Late Jurassic shallow and deep marine sands are present in the Hugin formation and the intra-Heather and Draupne formations, as well as Early and Middle Jurassic shallow marine to coastal/deltaic sands. Late Jurassic marine shales supply the area with prolific source rocks, while maturation, migration and timing ensured development of a prominent hydrocarbon province with significant remaining potential.
Our tailored workflow for GeoStreamer PURE data overcomes many of the imaging challenges related to this varied geological setting such as the resolution of shallow channels, injectites, and V-brights. The results offer new insight into established plays and reveal new opportunities.
Complete wavefield imaging (CWI) 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, as well as improved imaging of the Jurassic source rock, individual Jurassic fluvial-deltaic to shallow marine sandstones, sub-marine fans of Paleocene age, and intra-Jurassic and Paleocene mudstones.
