Acquisition

The 3D seismic leader

PGS aggressively pursued full 3D acquisition and processing technologies in the early 1990s when all the other seismic contractors were still adapting to small-scale 3D surveys from their historical emphasis upon 2D seismic acquisition.

Streamer seismic operations at PGS

Unquestionably, the heart of PGS’ leadership of the 3D streamer acquisition market can be directly attributed to the PGS Ramform vessel design. The PGS Ramform is one of the most distinctive and effective designs in the history of marine seismic technology, originally having been based upon naval stealth technology. The delta-shaped hull, with its extraordinarily wide beam, affords motion characteristics, stability and maneuverability well-suited to the smooth and efficient towing of ultra-high streamer counts, even in rough weather. Its wide stern provides a uniquely large working area that is ideal for the efficient handling of seismic equipment. Extremely low noise output ensures that the Ramform acquires higher quality data than conventional competitor vessels, in all conditions.

After their launch in 1995, the PGS Ramform vessels were the first to tow eight, ten, twelve, fourteen, and sixteen streamers. The PGS Ramform vessels remain the only seismic vessels capable of towing more than twelve streamers, and the only seismic vessels routinely towing twelve streamers.  This streamer towing capability provides PGS with unmatched survey flexibilities and operational safety.

With six Ramforms complemented by four standard seismic vessels, each record breakers in their own right, PGS has understandably established a global track record for 3D operational efficiency and innovation. PGS delivers the greatest value data products and services per square kilometer, free of the logistical constraints typical to many competitor operations.

In recent years, PGS has adapted the Ramform vessel capabilities to deliver long-awaited High-Density 3D (HD3D) data at affordable rates and survey efficiencies, providing the premier platform for all seismic data applications and products used by the petroleum industry.   The ability to tow massive numbers of streamers at close separation finally allows geophysicists, geologists, and production engineers to completely understand the seismic wavefields being recorded during each survey.  When the PGS acquisition strategies are complemented by the inherent flexibility of the PGS Ramform operations, then there is virtually no limit to the innovative solutions that can be provided to our clients – in all environments and for all challenges.

The PGS story does not stop with acquisition leadership

PGS is also aggressively developing “true” 3D data modeling, processing, visualization, and analysis technologies that complement the high quality 3D datasets being delivered by the PGS field operations.   At all times, the PGS emphasis is upon efficiency, accuracy, innovation, and reliable delivery.  No other company pursues the 3D seismic story like PGS – a testament to our early inception, our history of pursuing innovative technologies, and our continuing commitment to the petroleum industry.
