TGS insights give you the stories behind Energy data. These regular short 3-5 minute reads feature thought provoking content to illustrate the use of Energy data in providing insight, nurturing...

In the oil business, an undesirable event, incident or accident can put lives at risk, and cost the contractor or the customer tens of millions in lost revenues, cause damage to equipment and delays,...

There are many dynamic forces that can mask subtle reservoir signals, but a series of engineering innovations render TGS 4D GeoStreamer surveys relatively insensitive to them.

Triple source can improve data quality with better crossline sampling compared to standard dual source for a given streamer separation. Alternatively, if the crossline sampling is kept the same,...

Seeing under salt is not the only way more azimuths may benefit seismic imaging. The extra information also facilitates more accurate modeling of complex structures. Their acquisition is complicated...

Why haven’t marine vibrators been adopted for marine seismic surveying? In part, because of a general perception that their acoustic output is too low to yield useful images, and more importantly...
