Magseis Fairfield, the industry leader in ocean bottom seismic technology, boasts competitive advantages in technology, efficiency and QHSE, and we are able to definitively demonstrate our capabilities with our most recent project.

Our crews recently completed mobilization of the largest deepwater node fleet to date for our next project headed by TGS in partnership with SLB in the US Gulf of Mexico, including one node handling vessel, three source vessels and one support vessel, all manned by more than 200 offshore staff members at any given time. The project will be acquired with Magseis Fairfield’s ZXPLR system, our latest advancement in ocean bottom node (OBN) technology.

“The Magseis Fairfield team is focused on continuously pushing boundaries in ocean bottom seismic acquisition through the introduction of innovative technology and methodology, all part of our effort to provide new solutions for our customers’ challenges,” explains Per Christian Grytnes, CEO of Magseis Fairfield. “The use of our ZXPLR node technology, coupled with advanced ROV capability and new source acquisition methodology, represents a true evolution in deepwater acquisition programs. We are extremely proud of the effort and collaboration that has gone into fielding this unique OBS fleet which will set a new standard in our industry.”

The ZXPLR system offers operators flexibility and scalability, meeting the needs of the larger exploration surveys in deeper water. This survey area, approximately 7900 sq km, includes 18 surface obstructions and hundreds of seabed obstructions, demonstrating the value of Magseis Fairfield’s experience and improved deployment and retrieval technologies, and our ability to work in difficult environments and around surface and seabed obstructions.

96 nodes can be connected to the DCCS (Data Collection and Charging Station) and nodes can be put into acquisition mode, charged, and collected via smart chargers and Z-Recorder. The collection and charge cycles can vary based on the amount of data collected but usually ranges from 2 to 4 hrs.

Embarking on a deepwater project of this size and complexity came with its own set of unique challenges, but the Magseis Fairfield team was able to adapt and overcome. Relying on lessons learned from previous campaigns in both Brazil and the USGOM, the team was able to successfully mobilize the promised fleet six days ahead of schedule, equipped with new ROV technology, a new dual gun controller shooting method, and strategically placed source vessels from our suppliers.

This latest project sets a new industry standards for sparse node deployment, and reaffirms the value the Magseis Fairfield team can add to OBN acquisition.
