LYSAKER, Norway -- Petrobras has contracted PGS to install a permanent seismic monitoring system in the Jubarte field in the North Campos basin, offshore Brazil’s Espirito Santo province.

PGS will deploy its OptoSeis fiber-optic system for the program, as well as performing seismic acquisition and data processing. The technology is claimed to provide richer data than competing optical systems, and is certified for reliability for the life of the reservoir.

Initial work will cover a 245-sq km (94.6-sq mi) portion of the Jubarte field in water depths of 1,240-1,350 m (4,068-4,429 ft). Depending on the results the service could be extended to cover the entire field.

The company believes this project will advance the use of geophysics for reservoir surveillance, particularly 4D/4C seismic, to map the flow of fluids in Brazil's deepwater reservoirs.

Per Arild Reksnes, executive vice president New Ventures, PGS, said. "OptoSeis provides high quality seismic on demand for both new and mature fields.

“The data from the system will give the basis for improved decisions on well placements and IOR/EOR programs. This will increase the recovery factor, which is vital for the commercial success of expensive deepwater field developments," he said.
