No bigger changes in the oil and gas industry have occurred than in the deep and ultra-deepwater exploration and production segment. Here, exploiting these enormous reserves is critical for meeting the long-term global demand for oil. And here is where FairfieldNodal excels. Our Z3000® and ZLoF® (Z Life of Field) deepwater seismic data acquisition systems are made to solve today’s E&P challenges.
High-stakes field development and high-quality data.
Due to the magnitude of expense associated with deep- and ultra-deepwater field development, stakes are higher than ever—and mistakes can be costly or even fatal. So that the operator knows where to drill, having the best seismic image makes solid economic sense.
Additionally, operators are looking for new ways to optimize productive capacity of existing reserves versus exploring for new ones, which come with significantly higher lifting costs. This shift in strategy also requires higher quality seismic data. This quality directly correlates to the reduction of risk and uncertainty in reservoir development.
Nodal technology: monitoring life-of-field performance.
The FairfieldNodal Z3000® system, which features the industry’s first deepwater node, is easily and repeatably deployed. Providing an exceptional quality image, it’s ideal for reservoir surveillance. Used in tandem with our ZLoF system, you can optimize your economics from exploration, through appraisal, development, and enhanced recovery for the lowest total cost of ownership of any 4D reservoir monitoring strategy.

Superior images for deep and ultra-deepwater fields.
In deepwater environments, challenges become more complex. And mistakes, more costly. To ensure that you make the right decisions over the life of field, you need a superior seismic image—much more than what a streamer survey can provide.
The FairfieldNodal Z3000® system gives you that image. With high-quality, high-fold 4D seismic data, you have a solid baseline survey, giving you the power to monitor your reservoir and react to changes over time. Much more reliable and easily deployed than a permanent reservoir monitoring (PRM) system, the Z3000 helps you achieve the lowest total cost of ownership of any acquisition strategy.
Where streamer falls short.
The conventional approach to dealing with these high costs is to make due with legacy seismic data often collected by towed streamers. While this approach makes sense in some cases—initial exploration activities, for example—it doesn’t provide the superior, full-azimuth, long-offset image that nodes provide. This is what operators need to understand how the reservoir is performing, plan intervention activities, and avoid significant economic and HSE-related risks.
Nodal and 4D—the essentials for success.
4D seismic is essential for exploiting existing reserves and monitoring how the reservoir responds to production management. Successful 4D analysis requires not only 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.
Towed-streamer acquisition cannot provide an adequate baseline or monitor survey necessary to measure these changes over the life of field. When 4D seismic monitoring is needed, a traditional trenched cable permanent reservoir monitoring (PRM) system is often used. In deep and ultra-deepwater, however, PRM systems are expensive, technically risky and unreliable. Only nodal technology addresses all of these issues.
