The Triple Junction revealed by GeoStreamer
Website Map for Survey PGS16902VIK
PGS has applied its state-of-the-art processing workflow to this regional GeoStreamer dataset. PGS16902 is available as a depth migrated volume and covers the triple junction between the Viking Graben, Central Graben and the Witch Ground Graben.
The survey covers the gas discoveries in the Sleipner area in Norway and the fault-bounded Brae trend in the UK. Paleocene, Jurassic & Triassic are the key reservoir levels in the area. PGS16902 will unlock the potential of other stratigraphic levels and of the Ling Depression.
PGS combines newly acquired 2015 and 2016 acquisitions with a complete reprocessing of 2012 vintage data to produce a boundary free, state of the art volume. CWI, modern demultiple, and depth migration adds value to this area by a combination of library growth and modernization.
