  • TPS Tuned Pulse Source low frequency broadband marine seismic source deployed at sea (1280x720px)
    • Overview

      TPS

      TPS, a single point marine source,  delivers true broadband performance, with useful signal below 1 Hz for FWI and deeper imaging while retaining the high frequencies needed for detailed seismic imaging.

      Designed for OBN, 4D and towed streamer surveys, TPS can be leased on any vessel.

      Highlights

    • TPS Tuned Pulse Source deployed on Gulf of Mexico OBN survey for sub-salt FWI imaging by Sercel (573x430px)
    •  

      TPS improves velocity model building in complex geology, providing the low-frequency content needed for advanced FWI without compromising the high frequencies required for detailed seismic imaging.

       

      For 4D surveys, it delivers deeper penetration, better repeatability and greater sensitivity to reservoir changes. Independently assessed by JASCO for its environmental performance, TPS was also validated by NOAA Fisheries and BOEM as having the lowest environmental footprint among available ULF sources.

       

      TPS is available for lease per project on any contractor vessel, with field service, crew training and source design services also available.

      Key Benefits

      Geophysical Benefits. Image better.

      Sub 1 Hz FWI signal. Below what any other competitor delivers.

      TPS is the best in class among low-frequency sources. It is the only source with a bubble frequency that is less than 3 Hz and delivers a useful signal below 1 Hz. TPS is the best source for building blocky reservoir models. 

      • Improved imaging under salt and basalt
      • Mitigation of cycle skips in FWI
      • Reduced FWI turnaround time
      • Improved resolution thanks to reduced side lobes
      • Reduced dependency on well logs to provide the low frequency content for reservoir characterization
    • TPS low frequency seismic source sub-salt imaging FWI below 1 Hz signal for velocity model building (573x430 px)
    • Operational Benefits. Stay safer.

      Simpler deployment. Wider weather windows. 

      TPS simplifies source operations with fewer components under a single float for easier deployment and retrieval and better source control. Unlike an array or a cluster, its point-source design provides greater tolerance to high swell, extending the weather window and helping crews stay productive for longer. A safety check valve also prevents auto-fires during air drainage.

      Safer deployment and retrieval, with prevention of auto-fires.

    • TPS plug-and-play marine seismic source single float deployment for safer offshore operations (573x430px)
    • Environmental Benefits. Be greener.

      Independently validated as the smallest footprint ULF source on the market.

      TPS minimizes cavitation and high-frequency acoustic emissions, reducing disturbances to marine life. Its design supports smaller exclusion zones, with most energy generated at infrasound levels that are harmless to marine fauna.

      • Reduced high-frequency emissions, sound pressure levels, and sound exposure levels.
      • Reduced exclusion zones and a lower duty cycle.
    • TPS broadband marine seismic source - reduced exclusion zones and lower marine mammal acoustic impact (573x430px)
