Until recently, interest in the petroleum prospectivity offshore West Greenland has been sporadic at best. No surprise then, that exploration off the country’s western coast dates back to a previous...

Geophysicists need seismic data to convey a reliable, geologically meaningful picture of the subsurface both at the prospect and geologic system levels. This requires that spatial sampling be...

T GS always had, and still has, a very different philosophy from most seismic companies, with a distinct business model," Hank explains. "In effect, TGS is primarily a marketing organisation, close...

A pre-stack depth migration project has been undertaken to better image the deep water salt and associated geology of offshore Nova Scotia, Canada. A 28,000 kilometer regional grid (6x6 km) of 2D...
