Petrobras is awaiting approval from the Brazilian Institute of Environment and Renewable Natural
Resources (IBAMA) to begin a major 4D seismic project in the Santos Basin.
The Brazilian state-owned oil and gas company is planning a 4D seismic project in the 1,500
square kilometre Lula Field pre-salt area of the Santos Basin offshore the state of Rio de Janeiro.
It hopes to gather continuous data to better map oil and gas reservoirs in order to improve exploration
and production activity in the area.
Petrobras will need to install nodes on the field’s seabed and commission a seismic vessel to carry
out the work.
It has previously installed long-term 4D seismic nodes for continuous reservoir monitoring in other
areas of the Santos Basin.
Petrobras has used the technology in the Marlim field since 2005, and also in other areas of the
Campos Basin such as the Roncador, East Albacore, Barracuda and Caratinga fields.
