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.

Every exploration manager knows estimates are more reliable if they use better data. Multisensor GeoStreamer acquisition provides three key platforms for seismic imaging. TGS advanced imaging...

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,...

Ramform Sterling recently completed TGS' 25th multisensor broadband GeoStreamer 4D survey since 2012. This is the fourth 4D GeoStreamer survey from TGS this year and the rate is increasing. This...

TGS least-squares solutions compensate for wavefield distortions and dramatically improve the imaging and the interpretation of complex structures. Here are a few benefits of the technology: Corrects...

New least-squares solutions are emerging that compensate for wavefield distortions and dramatically improve the imaging and the interpretation of complex structures. Corrects for wavefield...

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...

GeoStreamer is regularly claimed to be the optimum prestack platform for seismic inversion and quantitative seismic interpretation studies, but what does this mean? Competitor case studies often show...

TGS publications highlight fundamental areas where advances in marine 4D acquisition and processing are improving 4D repeatability and the detection of weak changes in reservoir state.

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...
