The right image is always the right answer.

Around the globe, nearly every producing subsea field development is characterized by crowded infrastructure. Towed, wide-azimuth (WAZ) streamer acquisition—which can be used in open water to evaluate untouched block acreage—is simply impractical in these congested areas. Moreover, this data doesn’t provide much value beyond early exploration.

Other ocean bottom cable (OBC) systems come with unreliable terminations, connectors, power distribution, and data transmission, making them prone to technical downtime, driving up costs when you can least afford it.

Ocean-bottom node (OBN) acquisition addresses all of these issues to deliver the right image at just the right time.

OBN: simplicity and an impeccable safety record.

FairfieldNodal ocean-bottom nodes are easily deployed and retrieved, even in areas that are remote, difficult to access, or ecologically sensitive. Our innovative back-deck handling system automates the process, further reducing risk and the need for additional personnel.

Superior economics beyond exploration.

OBN technology excels in the later stages of life of field by delivering high-quality, full-azimuth images for production seismic. But operators are now beginning to understand the importance of having the best quality image from the earliest stages of field development.

To make the most of their investment, operators must acquire seismic data that brings value throughout the life of field. Whether selecting an initial well location or characterizing a productive field, OBN seismic data acquisition provides a superior image and a higher level of certainty about where to drill and how to develop reserves.

A superior image. A better baseline.

Our OBN solutions can help ensure that the reservoir is as productive as possible over time by providing the highest quality baseline 4D surveys and repeat 4D monitor surveys. We also offer a nodal alternative to conventional PRM systems for safe, reliable, and cost-effective reservoir monitoring and management.

FairfieldNodal acquisition advantages

  • Longer offsets—typical sustained source-to-receiver offsets of 12 km or more, depending on geometry
  • Full azimuth data—a nearly perfect offset and azimuth distribution, only possible where source and receivers are decoupled; a critical component for imaging complex structures
  • Continuous recording capable of producing records of any length
  • Survey design flexibility for minimal gaps in coverage area
  • Streamlined passive-rope node deployment and recovery in shallow water
  • Superior coupling and vector fidelity—nodes accurately record incoming wavefield without distortion due to direction of propagation
  • Onboard quality assurance, quality control and data formatting
