Petrobras announces first oil from new well in Lula field

RIO DE JANEIRO -- Petrobras commenced production from well 7-LL-22D-RJS in the Santos basin’s Presalt Lula field (Lula NE Pilot area) on May 9.

This well, with a production potential of 26,000 bopd, 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 m. The wellhead is located at a water depth of 2,130 m.

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 bopd in the third quarter of 2014.

When deployed, the RSB is immune to platform movements. This means that rigid steel pipes (steel catenary risers) can be used in some parts of this ultra-deepwater project.

The buoy measures 40 x 52 m and weighs 1,936 metric tons. It is attached to the seabed by means of eight 1,828-m 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%).
