The world’s first full-solution deep-water PRM (Permanent Reservoir Monitoring) project in the Jubarte field in Brazil for Petrobras was deployed in water depths between 1200 ‐ 1350m in 2012. The project includes a fully fiber-optic ‘Wet-End’ on the seabed, topside ‘Dry-End’ on the P57 FPSO, marine installation of the system in deep-water, the acquisition of active data using a shooting vessel, the acquisition of passive seismic data as well as data-processing of both active and passive data. The paper presentation shall also briefly describe how the unique optical system works. The system itself includes a wide range of items ‐ from top-side Opto-electronics to a riser and lead-in cables, a sub-sea hub with optical wetmates, as well as the actual seismic array cables with optical 4C (4-component) sensor stations over the field. Introducing and implementing new technology has traditionally been a challenge in the oil industry. This project was started initially at Petrobras CENPES research center. In projects such as this one, the successful implementation of a full solution required a multi-disciplinary team from the operator as well as the service company and this case demonstrates a successful joint effort by Petrobras Reservoir Geophysics and Jubarte asset teams as well as PGS.
