PGS OptoSeis at Jubarte
Located 70 km offshore Brazil at a water depth of 1 300 m Jubarte lies in the northern Campos Basin, in block BC-60. The discovery in January 2001 was Petrobras' largest since 1996, with oil reserves estimated at 600 million barrels. Though Jubarte lies in a pre-salt area, the reservoir is post-salt. In late 2012 a permanent monitoring system using PGS OptoSeis® was installed over 9 sq. km of the field at 1 200 - 1 350 m depth, with plans to cover more of the 245 sq. km field in the future.
