Production begins from Petrobras’ well at Lula field

Petrobras on Friday began production from well 7-LL-22D-RJS in the Santos Basin’s Presalt Lula field (Lula NE Pilot area).

This well, with a production potential of 26 thousand barrels per day (bpd), is connected to FPSO Cidade de Paraty via a new platform-connection system deployed for the first time in the Lula field. Using this system, the riser section of the production pipelines is supported by a submerged buoy at a water depth of 240 meters. The wellhead is located at a water depth of 2,130 meters.

During 2014, a further 6 wells will be connected to the platform (4 production wells and 2 injectors) using the Riser Support Buoy (RSB) system, ramping up FPSO Cidade de Paraty to full production capacity of 120,000 barrels of oil per day (bpd) in the third quarter of 2014.
Pioneering system – When deployed, the RSB is immune to platform movements. This innovation means that rigid steel pipes (Steel Catenary Risers – SCR) can be used in some parts of this ultra-deep water project.

The buoy measures 40 x 52 meters and weighs 1,936 metric tons. It is attached to the seabed by means of eight 1,828-meter steel tendons, each fixed to one of four stakes in the seabed.
Subsea 7 built and deployed the system. The buoy is capable of stabilizing pipes from up to 4 production wells and 3 injection wells. Deployment of the system commenced on December 19, 2013 and was completed on February 7, 2014. Deployment of the SCRs was completed on April 1, 2014, for connecting the first three production wells.

Connection of well 7-LL-22D-RJS to the FPSO was completed on May 5, 2014, when the flexible pipelines were deployed. A second buoy is already in position and ready to stabilize the SCRs used for production and injection.
FPSO Cidade de Paraty went into operation on June 6, 2013. Well 7-LL-11-RJS was connected directly to the platform and produces some 30,000 bpd. The Lula field is operated by Petrobras (65%) in partnership with BG E&P Brasil Ltda (25%) and Petrogal Brasil S.A (10%).
