High quality, low risk, and easy deployment in transition zones.

The Z100 system gives you the ability to acquire high-quality seismic data from the beach to 300 meter depths, with minimal HSE risk. The system is lightweight, making deployment a breeze. Once deployed, it records continuously, giving you the image you need for successful, long-term reservoir management.

Superior images for tough environments.

When it comes to marine seismic data acquisition, transition zones are among the most challenging environments you’ll encounter. Shallow and ecologically fragile, they make the deployment of seismic-acquisition equipment difficult, dangerous, and costly. Wrangling people and cumbersome cables is increasingly problematic the closer you get to shore. And it is safe to say that conventional towed-streamer acquisition is not a real option in transition zones.

A Z100® marine node system provides an operator with superior seismic images in these hard-to-manage transition zones. Here, where risks are greatest, making the right decisions—whether they’re related to exploration or reservoir management—depends on having the right data. Z100 is the right system for obtaining that data.

Z100 node deployment is a breeze anywhere in transition zones—shallow water, swamps, on the beach, and all points between. Best of all, you never compromise the quality of your image or the economic viability of your field.

Lightweight, autonomous and HSE-friendly

Easily deployed and retrieved

Rated to 300-meter depths

Records continuously, with no troubleshooting required

Integrates well with other nodal systems, land and marine

No unreliable cables, connectors, or telemetry


Deep, rich seismic data in shallow water

The Z700 system is easily deployed, requiring smaller crews and a minimum two-vessel configuration–one node management and one source vessel. No cables, no leakage, no headaches. Better yet, you get a superior image for better appraisal and brownfield development, improving your economics over the life of your reservoir.

A superior choice for complex, ecologically sensitive environments.

Shallow-water zones come with numerous challenges—hazardous obstacles, complex infrastructure, and ecologically sensitive environments. Bulky ocean-bottom cable (OBC) systems are a hassle to deploy. Technical issues and downtime associated with them drive up acquisition costs.

The Z700 system dramatically simplifies acquisition, while providing you with the superior, long-offset, high-fold seismic image you need to make the best decisions over the productive life of field.

Superior images for deep and ultra-deepwater fields.

In deeper water, challenges are more complex. Mistakes, more costly. Making the right decisions requires a superior seismic image—much more than what a towed streamer survey can provide. The Z3000 system provides that image. High-quality, high-fold 3D seismic gives you a solid 4D baseline survey, along with the power to monitor your reservoir and react to changes over time, and plan intervention activities. The safety, flexibility, and scalability of the Z3000 helps you achieve your seismic monitoring objectives at the lowest total cost of ownership of any competing system.

Nodal and 4D—the essentials for success.

Successful 4D analysis requires not just a quality baseline nodal seismic image, but the ability to repeat monitor surveys over time. Subtle changes in reservoir response can only be measured with the highest quality seismic images that repeatable, high signal/noise, full-azimuth nodes provide.

Clarity meets flexibility.

Production managers and exploration teams alike continually seek greater safety, efficiency, and data quality in seismic acquisition. The latest advancement in OBN technology, ZXPLR, delivers. A hybrid system capable of dual-mode deployment in both deep and shallow water, it’s designed to further simplify node management, maintenance, and inventory control, reducing overall costs by supporting multiple operations.

Safety, efficiency and ease of deployment—at any depth.

ZXPLR can be deployed with a passive rope or by ROV. In deepwater applications, High-Speed Loader (HSL) capacity is increased, employing mid-water docking and active heave controls on HSL and ROV systems. In shallow water operations, hands-free rope connection/disconnection and automated retrieval/deployment enhance safety and efficiency.

Better data, greater scalability.

Emerging imaging technologies require densely sampled, longer offset, full-azimuth data. ZXPLR can deliver it, more economically than ever. It features redesigned deployment methods that allow for exploration-scale surveys in deep or shallow water.

Onboard data quality control is also automated, enabling onboard processors to quickly and consistently verify node data, while simplifying downstream processing and node performance tracking

High-quality 4D data with enhanced repeatability.

An essential tool for deepwater reservoir monitoring, 4D seismic requires two things—dense, high-quality data and repeatability. The ZLoF® System, short for Life of Field, provides both at a lower cost than conventional methods, such as cabled Permanent Reservoir Monitoring (PRM) systems.

Delivering full-azimuth 3D and 4D seismic on demand, ZLoF is capable of a five-year deployment life and 500-day cumulative recording period, allowing for multiple monitoring surveys before node recovery. Because repeatability is comparable to PRM installations, nodes are viable candidates for autonomous reservoir monitoring.

Logistical freedom.

Based on proven OBN technology, ZLoF nodes combine low maintenance and high reliability, with a minimal footprint around complex infrastructure. No cables or trenching required. No pipeline crossings. No ties to production facilities. These advantages all add up to lower maintenance costs and greater safety.



Little technical installation risk — no cables, pipeline crossing or trenching

Low operational footprint — no ties to production facilities

Excellent repeatability for detecting subtle 4D changes

High reliability at lower cost — nodes can be replaced if necessary

High vector fidelity, good coupling, and high signal-to-noise ratio for superior imaging

Flexibility — nodes can be moved, replaced, or added to as development plans change

Monitor survey costs are low, single-vessel operation
