We have set the standard in OBN acquisition using proven technology to increase quality and achieve safe and efficient operations.


Setting the Standard for OBN Acquisition Since 2003

Since 2003, we have set the standard for OBN acquisition. We’ve been raising it ever since.

Built on more than 40 years of marine acquisition experience, we’ve refined this revolutionary technology to push the limits towards increasingly greater quality, safety and efficiency.

We've completed over 130 OBN acquisition surveys with over a million unique deployments. Our operations have spanned the globe, from the Barents Sea, the North Sea, the South China Sea and the Red Sea to offshore Brazil, North Africa and the Gulf of Mexico.

Our reputation stems from a wealth of satisfied customers including IOCs, NOCs and independents.


Meeting Challenges in Any Environment or Depth

Our suite of proprietary MASS and ZNodal acquisition technologies, which are fully modular, can be deployed by rope, cable and ROV in water depths from 0-4,000 meters in all environments. That includes in and around dense infrastructure and in sensitive environmental and transition zones. With automated node handling, deployment and retrieval systems, operations are safer than ever.

Today, TGS has the largest node inventory in the world. As our technology advances, you benefit from the world’s greatest survey flexibility — higher quality data acquired faster and more cost-effectively.
