PGS has a productive core fleet of Ramform vessels, comprising four Ramform Titanclass vessels, one Ramform S-class vessel and one Ramform V-class vessel. All models have delta-shaped hulls and uniquely wide back decks, enabling highly efficient seismic acquisition. The breadth of the Ramform back decks, 40 meters on S-class and V-class, and 70 meters on Titan-class, provides unparalleled streamer handling capability. These vessels deliver industry-leading performance in deployment, acquisition and streamer recovery.
The Company also operates two conventional-hulled vessels on longterm charters, which are used selectively depending on seasonal demand swings.
Operational performance is a measure of how well PGS utilizes the time available to acquire seismic data. Downtime (technical and maritime) as a percentage of total PGS fleet time has decreased steadily over 20 years, matched by improving performance over the same period. To deliver the best possible product in the most effective manner for all stakeholders, each acquisition project requires cooperation between the commercial business areas, and a streamlined organization within Operations & Technology, which includes the four main areas: dedicated project-focused planning; delivery and support teams; robust and professional vessel operations; and cutting-edge marine and imaging technology development.
PGS leads the industry in HSEQ performance and aims to sustain and improve this, with a focus on operational and safety culture. PGS prioritizes safe, ergonomic office and work spaces, good health and recreation facilities for all employees.
GeoStreamer
GeoStreamer multisensor streamer technology is unique to PGS. In addition to delivering superior seismic data quality, GeoStreamer significantly widens the operational window in which data acquisition can be performed, since it can be towed significantly deeper than a conventional streamer, escaping weather effects without compromising data quality.
Customer benefits include shorter cycle times and more reliable images of the subsurface. The enhanced operational characteristics of the Ramform Titan-class vessels exploit the full potential of the improved weather window created by GeoStreamer technology.
Reliable GeoStreamer data is better for reservoir interpretation and characterization,
and PGS has developed several imaging products that build on that advantage. Separated Wavefield Imaging (“SWIM”), Complete Wavefield Imaging (“CWI”) and Full Waveform Inversion (“FWI”) technologies all benefit from GeoStreamer data by exploiting surface multiple wavefields, refractions and diving waves, and primary reflection wavefields. PGS’ advanced imaging solutions create new play opportunities and reduce cycle times to recovery. PGS’ robust visualization tools enhance customers’ target interpretation, characterization, and decision-making processes.
Research & Development
PGS invests in research and development that can be commercialized, targeting geophysical and engineering solutions that improve operational efficiency, enhance data quality or shorten data delivery lead times. PGS aims to create sustainable competitive advantages and solid return on the investments.
