PGS Re-Maps Producing Areas of North Sea with GeoStreamer (Norway)


In 2011, PGS is looking for more unexpected and the unexplored targets in key producing areas of the North Sea with a new wave of GeoStreamer MultiClient 3D.

Near-field exploration potential

GeoStreamer® technology promises to unlock the excellent near-field exploration potential still offered by the North Sea. The key is better imaging and understanding of the subsurface. PGS has a bold program of new acquisitions in the Norwegian Sea, Faroes-Shetland Basin, Viking Graben and Central North Sea.

The GeoStreamer 3D datasets acquired so far have clearly proved the ability of this unique technology to offer expanded frequency bandwidth, with far better imaging of deeper structures, and very high frequency detail in the shallower sections.

Viking Graben, Central North Sea & Norwegian Sea

From June to September 2011, PGS will acquire over 4500 km2 of new 3D GeoStreamer® data in the Viking Graben. Building on the 2009 and 2010 programs this will result in a combined dataset of around 11.000 sqkm.

In the Central North Sea, 1500km2 new GeoStreamer acquisition promises better insight from both producing fields and open acreage in this mature area.

Following the successes of the Laggan, and Rosebak / Lochnagar wells and the Lagavulin discovery, the sub-salt potential of the Faoes-Shetland basin is generating industry interest. PGS is extending its coverage in this region in 2011 with the Corona Ridge and FSB2011 programs.

In the Norwegian Sea, the 3300 km2 HVG2011 survey includes the recent Victoria discovery – the largest undeveloped gas field in the area. Resolution and stratigraphy are the priority at target horizon depth 4,200 – 5,700 m which is ideal for GeoStreamer.

In oil provinces around the world, new deeper targets have emerged from beneath shallower producing areas. GeoStreamer offers a fresh look and a new set of tools to decipher the continuing hidden potential of the North Sea.
