TRUE CABLE-FREE Z700® Name your seismic challenge. We’re all answers.
IN THE WORLD’S WORST CONDITIONS, OR THE WORLD’S BEST,FOR TROUBLE-FREE PERFORMANCE,
THIS IS YOUR ANSWER.
Ocean-bottom cables have met their match. The Z700 nodal
acquisition system delivers quality data more efficiently and with less
effort than conventional systems. Thanks to their unique cable-free
design, Z700 4C nodes offer you extreme flexibility, allowing you to
design surveys to meet your goals, without limits, at water depths from 0
to 700 meters.
Z700: THE EFFICIENT ALTERNATIVE TO OBC.
Years ahead of bulky conventional systems, Z700’s unique true
cable-free nodes streamline deployment. You can safely place the
nodes very precisely wherever you like, and count on them to record
quiet, 4C data continuously, without the least bit of troubleshooting
required. Then, using a simple passive rope system, the crew can just
as easily retrieve the nodes for data transfer, QC, recharging and
redeployment.
LONGER OFFSETS, ANY AZIMUTH, LONGER RECORD LENGTHS
Z700 puts you in control. Without tons of cables or streamer lines
to deal with, virtually any geometry is possible. Nodes can be closely
spaced at any interval, with as many lines as needed. Shot lines provide
full or all-azimuth imaging in a very quiet environment to deliver a
superior, high-fold dataset.
SIMPLICITY, FROM START TO FINISH.
Z700 Advantages• Greater productivity• Multi-azimuth illumination• 4-component data• Reduced HSE exposure• Proven reliability• Longer offsets

“We used the Z700 system for a 2D project in the Red Sea and were totally impressed. The project would have been impossible with any other system.”

TROUBLE-FREE, SHALLOW-WATER SEISMIC
• Easily positioned among obstructions – no gaps, or in open seas
• Entirely self-contained – no external circuitry
• No troubleshooting of spread
• Greater productivity and channel capacity
• Multiple deployment capabilities
• Faster, more efficient deployment and retrieval than OBC
• Quick, safe and easy retrieval
• Simultaneous data download and battery recharging
• Automatic, full-system QC testing after every data download
Data collection and charging
While data is downloaded, node batteries are recharged, followed by automatic, full-system QC testing. Nodes are ready for redeployment in less than 8 hours.
Efficient deployment and retrieval
Z700 nodes are easily deployed and retrieved via a simple passive rope system. The system’s streamlined operation reduces HSE exposure.
No more data gaps to worry about
The Z700 system lets you go where other systems can’t, placing nodes right next to surface obstructions and eliminating the huge gaps in your data that can make it difficult to feel confident about your reservoir plans.
