Petrobras Will Adopt Technology Developed by NASA to Monitor Oil Signals in the Equatorial Margin, Increasing Accuracy and Efficiency of Exploration Research
Petrobras has been officially accepted into the early users program of the NISAR mission, an innovative project by NASA and the Indian Space Research Organization (ISRO). The objective of the mission is to monitor changes in the Earth’s surface via satellite.
The Brazilian state-owned company will use this technology to monitor the Brazilian Equatorial Margin, a strategic region for oil exploration, located between the states of Amapá, Pará, and Maranhão.
Innovative Technology for Environmental Monitoring
The NISAR mission is set to launch in 2025 and features a groundbreaking system for collecting SAR (Synthetic Aperture Radar) images, which will be used in the Brazilian Equatorial Margin Environmental Geo-Chemical Observatory project (ObMEQ).

Metsul warns of an intense extratropical cyclone in the South Atlantic with rain, winds above 100 km/h, and the advance of a cold air mass over Southern Brazil, dropping temperatures to as low as 5°C in Rio Grande do Sul and Santa Catarina.
The technology offers the capability to capture high-resolution images of the Earth’s surface, regardless of weather or lighting conditions, something essential for Petrobras’s area of operation.
The NISAR satellite operates with two radars: a L-band radar provided by NASA and a S-band radar provided by ISRO.
These radars emit microwave signals that can penetrate clouds and operate at night, enabling data collection in any condition.
NISAR will be able to scan nearly the entire surface of the planet twice every 12 days, providing detailed data on natural phenomena such as soil changes, glacier melting, displacements caused by earthquakes, and landslides.
Strategic Partnership with Petrobras
In relation to its use by Petrobras, the technology will benefit the company in monitoring the coastal region of the Equatorial Margin.
This area is highly relevant for oil exploration, and ObMEQ aims to improve environmental and geochemical management of this region. Renata Baruzzi, Director of Engineering, Technology, and Innovation at Petrobras, explained the cooperation with the NISAR mission, highlighting the converging scientific interests between the two projects.
The partnership will allow for information sharing between the Brazilian team and the mission specialists, optimizing the observation plan and benefiting Petrobras in the exploration and environmental monitoring process.
NISAR will bring a significant advancement by monitoring even the oil signals in the waters, as well as assisting in the management of natural resources and combating deforestation and climate change.
The mission will enable the measurement of millimeter-scale displacements of the Earth’s surface, creating 3D maps that identify gradual changes over time.
The satellite will also be capable of performing a detailed analysis of the Earth’s surface, focusing on detecting changes affecting both the environment and natural resources.
The launch of NISAR will take place at the Satish Dhawan Space Center in India, marking the first technical collaboration between NASA and ISRO on an Earth observation mission.
