Two major energy companies have contracted providers of ocean bottom node technology to monitor deepwater oil and gas fields in South America and the US Gulf to optimise hydrocarbon recovery
PXGEO has won two contracts from Petrobras-led consortia to provide seismic data acquisition and monitoring services in the Santos Basin, offshore Brazil.
These contracts will run consecutively in 2026 and will use ocean bottom node (OBN) technology to monitor fluid flow through oil and gas reservoirs, extending PXGEO’s business presence in Brazil as demand for OBN surveys and field monitoring services is increasing across the Atlantic margins.
In Brazil, PXGEO will deploy its proprietary MNode 4C OBN technology. These nodes have 300 days of battery life for extended deployment time, which PXGEO said is suited for larger, more complex and uninterrupted surveys as there is less need for frequent retrieval and redeployment, projects are less challenged by timelines issues and there is less need for vessels on standby.
“These latest contracts are a significant win for PXGEO as we consolidate our presence in Brazil with MNode technology benefiting Petrobras and its partners,” said PXGEO head of sales in Americas, Brent O’Brien.
“OBN technology is widely recognised for delivering the seismic clarity needed to tackle intricate geology,” he said. “Operators can better identify bypassed hydrocarbons, track fluid movement within the reservoir, and monitor compaction with confidence.”
This data enables energy companies to optimise reservoir performance and make investment decisions to maximise recovery rates in new and mature fields.
