  • ZXPLORe
  • Z700®

MASS III

TGS-MASS III

Enhanced Flexibility and Efficiency

The MASS III system combines an ultra-compact design with extended recording capabilities and a fully programmable CPU, offering unmatched flexibility in the field. Its robotic handling system reduces manual intervention and lowers failure rates while improving operational safety. MASS III is well suited for projects that demand high logistical efficiency and dependable, repeatable performance.

ZXPLORe

TGS_ZXPLR

Versatile Deep and Shallow Water System

The ZXPLORe system delivers adaptable node deployment for both deep and shallow water environments. It supports deployment via passive rope or ROV and includes a high-speed loader (HSL) that enhances turnaround time in deepwater operations. This system is ideal for projects with diverse bathymetry and environmental constraints.

Z700®

TGS-Z700

Life of Reservoir Efficiency

Designed for water depths up to 700 meters, the Z700 system features automated back-deck handling for safe and reliable deployment. It performs well in transition zones, near complex infrastructure and in ecologically sensitive areas. With continuous data recording and minimal HSE impact, the Z700 supports detailed imaging throughout the reservoir lifecycle.

A Flexible Solution for All Needs

TGS OBN technology supports safe, efficient and high-quality seismic acquisition for a range of offshore goals, from early exploration and development planning to carbon storage monitoring and reservoir management. With a focus on flexibility, we align systems and operations to your timeline, environment and data needs. This adaptability makes TGS a reliable partner for any OBN campaign, regardless of complexity.

Adaptable Deployment Options

TGS offers multiple node deployment methods to suit a wide range of operational needs and environments. Our systems support nodes-on-a-rope (NOAR), remotely operated vehicle (ROV), and node-drop configurations, providing flexibility for both deep and shallow water campaigns.

ROV deployment is especially effective for 4D reservoir monitoring, where repeatability is critical. The compact node design allows for more nodes per skid, improving efficiency and reducing downtime. Combined with scalable, automated handling systems and hands-free data download, this approach enables faster, safer operations with greater consistency.

Portable Source Solutions

TGS extends its acquisition capabilities with advanced portable source technologies designed for consistent and repeatable seismic input. Since 2003, we have supported permanent reservoir monitoring (PRM) through an end-to-end approach that includes system design, deployment and operation. Our expertise in PRM and containerized source systems helps reduce variability across surveys and ensures a stable energy source for accurate 4D imaging, even in technically challenging conditions.

Modular Designs

TGS ocean bottom node systems are modular by design, supporting project scalability and deployment anywhere in the world. This flexibility helps reduce acquisition time and costs while adapting to a variety of technical and environmental conditions. By combining technical precision with operational agility, we deliver dependable results across the full spectrum of seismic acquisition needs.
