GeoStreamer X data reliability and accuracy have been reinforced in a First Break paper out in September. The paper shows how PGS' innovative solution, using multi-azimuth broadband seismic with wide-tow triple-source shooting, has overcome the main exploration challenges in the prolific southern Viking Graben.
The multi-azimuth multisensor data have enabled existing fields and known discoveries in the area to be accurately mapped and new leads and opportunities suitable for near-field exploration have been highlighted.
With improved understanding and characterization of the various reservoir intervals, evidence of additional nearby hydrocarbon potential has been revealed.
The integrated approach of acquisition, imaging and reservoir characterization has delivered encouraging results in a very cost-efficient and effective manner.
Several additional wells have been drilled following the Lille Prinsen discovery, to examine the potential in the deeper stratigraphic intervals such as the Jurassic sandstone and the Permian. In the image below, based on our elastic-attributes extraction on the pre-Cretaceous interval, clear indications of hydrocarbons are visible at the Upper Jurassic and Zechstein levels. These anomalies are of reasonable size and could constitute interesting near-field exploration targets.
