RONCADOR FIELD:CHALLENGES OF AN ULTRA-DEEPWATER DEVELOPMENT

摘要

The Petrobras Poster highlights the Roncador Field development, its deepwater productionrecords, and the associated technological key issues.Discovered in October 1996, by the wildcat well RJS-436, the Roncador Field is located in ultra deepwaters, ranging from 1,500 to 2,000 meters, in Campos Basin with 3 billion barrels oil equivalent totalreserves.The development plan will be in phases, besides the Early Production System that is already producing.This System is operating from the host unit Seillean, an FPSO chartered by Petrobras, having a capacity toproduce and process up to 20,000 bpd and store up to 306,000 barrels.The first phase came on stream in April 2000, and comprises the production semi-submersible P-36,installed at 1,360 meters water depth, equipped with processing facilities for 180,000 bpd. The oilproduction is transferred to the FSO unit P-47, located at 815 meters water depth.As a pioneer on the use of floating production concept, during the last 22 years, Petrobras has alwaysemphasized innovation and improvement based on its operational experience.Technologies such as: Drill Pipe Riser for 2,000meters water depth; Dynamically Positioned FPSO; Valvesand hydraulic actuators for operation in 2,000 meters of water; Steel Catenary Risers; Flexibles Risers (10")for 1,500 meters and flowlines for 2,000 meters water depth; Vertical Loading Anchors and PolyesterRopes are displayed.
