Z3000 Acquisition Overview
100% smarter seismic acquisition, 98+% data reliability
Featuring the industry’s first deepwater nodes, Z3000 technology is ideal when exceptional-quality imaging is needed. Though not intended to replace streamer acquisition for large-scale surveys, it has become particularly successful in both deep-water and congested shallow-water areas where cable-free nodes can be easily deployed.
FairfieldNodal pioneered node deployment via remotely operated vehicle (ROV) and was the first to implement dual ROVs for deployment and recovery from a single vessel, along with a proprietary subsea node loading system, for optimum efficiency.
Each Z3000 node is self-contained and comes with an exceptionally accurate clock and a new, extended-life lithium-ion battery.
A single person can manage up to 1200 nodes, thanks to the specially designed deck-handling system. The nodes are handled automatically, eliminating potentially dangerous, overhead swinging cranes.
Ideal for numerous deep-water challenges
- For enhanced subsalt imaging. With true all-azimuth capability, Z3000 technology is perfect for superior imaging beneath salt intrusions, prevalent in the Gulf of Mexico and notorious for distorting seismic signals.
- For time-lapse seismic (4D) applications. With repeatability and positional accuracy better than three meters, 4D capability is a fringe benefit of every node survey, further assuring effective reservoir management and monitoring.
- For infill voids. Platforms are often placed in the middle of a field, leaving streamers unable to acquire crucial seismic data. Z3000 can be used to fill in the gap around the infrastructure, or in conjunction with a streamer survey to record streamer and node data simultaneously. The data can be quickly merged into a transparent data set.
- For deepwater gas clouds. These obstructions make it nearly impossible to illuminate the geology with conventional acquisition methods. But since Z3000 units each feature a hydrophone and three geophones, the nodes are inherently multi-component (4C) capable, allowing them to record the converted wave.
