Seabed Geosolutions, a joint venture between Fugro and CGG, has just completed a deepwater proprietary 3D ocean bottom node (OBN) survey in the Santos Basin, offshore Brazil.

The survey, started in late 2018, covered the Buzios field, lying in around 2000 m water depth.

Fugro said on Wednesday that, utilizing Seabed Geosolutions’ Manta ocean bottom node system and ROV deployment systems, the project had operated in a congested deepwater area and delivered significant node deployment efficiency gains.

This is the fourth OBN survey completed by Seabed Geosolutions in Brazil.

“In close cooperation with Petrobras, we have completed the industry’s largest-ever OBN survey, spanning more than 1600 km2, in this giant pre-salt field in the Santos Basin using our new Manta OBN technology,” said Stephan Midenet, CEO of Seabed Geosolutions.”

Petrobras commented: “In view of this acquisition being the largest deepwater node survey ever performed, with a complex and evolving operating area having many production structures and FPSOs, Seabed Geosolutions’ effort and experience in successfully completing this job is second to none.

“Furthermore, the preliminary processing results indicate the quality of the data acquired is superb and will finally deliver structural insight to better characterise the Buzios field.”

It is worth mentioning that Axxis Geo Solutions last October also said it had completed the world’s largest OBN multi-client survey. AGS said that the Utsira multi-client OBN survey – in the North Sea, offshore Norway – covered an area of approximately 1,600 square kilometers.

It is also worth reminding that Seabed Geosolutions in October 2019 secured a letter of award to provide a 3D OBN survey in the Santos Basin offshore Brazil.
