Meet and exceed your seismic project challenges. Use our proven node technology to get rich seismic data to make the best reservoir decisions.

Connecting you with superior seismic through relentless node innovation.

Through the acquisition of Magseis Fairfield, TGS is the technology leader in ocean bottom node (OBN) innovation. 


OBN solutions

Our systems have been successfully deployed in the world’s most challenging environments, from ultra-deepwater to shallow transition zones, sub-salt, and onshore and urban areas. We’ve simplified the logistics behind getting the rich seismic data you need to make better reservoir decisions.

Inspired by miniaturization technologies in the mobile phone and military industries, we continue to push the limits of innovation in modular solutions, lighter-weight components and lower power consumption. Our equipment is backed by unsurpassed expertise and packaged to meet your project challenges. 


MASS I offers up to 65 days of recording time and operating depths from 0 to 3,000 meters.


MASS III delivers high quality 4C data with up to 150 days of recording time and operating depths from 0 to 3,000 meters, in a compact lightweight design. 


ZXPLR combines clarity with flexibility.


With easy, low-risk deployment, the lightweight Z100 is ideal for transition zones.


In shallow water of up to 700-meter depths, Z700 delivers superior high-density data.


Engineered to tackle onshore challenges, ZLand goes effortlessly wherever you need it.

Modular Configurations

Mobile, flexible and scalable, our OBN solutions can be containerized and shipped anywhere.

Various deployment options for greater efficiency

Our node systems can be fitted for deployment by either nodes-on-a-rope, ROV or Node-drop.

ROV deployment offers proven repeatability for 4D reservoir monitoring. The small size allows for more nodes per skid, improving efficiencies. The scalable, automated handling system and software, combined with hands-free data download, deliver an unrivaled speed of operations.
