Petróleo Brasileiro S.A., or Petrobras, announced that it started production at Papa Terra field Nov. 11, located at the south of Campos Basin, with platform P-63, which is connected to well PPT-12.
The FPSO (Floating Production Storage and Offloading) platform is anchored at a water depth of 3,937 feet (1,200 meters) and has the capacity to process 140,000 barrels of oil per day, compress 1,000,000 m3 of gas and inject 340,000 barrels of water. It is the first production system to be installed at Papa Terra.
The new FPSO comprises a set of production projects planned for this year as provided in the Business and Management Plan 2013-2017. The combination of reservoirs with oil varying from 14 to 17 degrees API and the deep waters made of Papa Terra one of the most challenging projects ever conceived by Petrobras, requiring the application of many innovative solutions.
Besides FPSO P-63, which will be connected to 5 production and 11 injection wells, the TLWP platform P-61 (Tension Leg Wellhead Platform) will also operate in the area. P-61, which will be connected to 13 production wells, is the first TLWP to operate in Brazil and will be towed to the location this month.
P-63 wells will be connected using flexible subsea pipes with electric heating, known as IPB (Integrated Production Bundle) and P-61 will use dry completion, which means that well controlling valves are located at the top of the platform rather than in the bottom of the sea. All 18 production wells will have centrifuge submersible pumps. The output of P-61 will be transferred in a multiphase flow to FPSO P-63.
P-61 will also have a TAD (Tender Assisted Drilling) support rig, which will be towed from China in the coming days. The oil will be offloaded through shuttle tankers and the gas not consumed on the production units will be reinjected in an adjacent reservoir.
The project is being developed by Petrobras (operator) in partnership with Chevron, with stakes of 62.5 percent and 37.5 percent, respectively, and is 68 miles (110 kilometers) off the Brazilian coast, at a water depth that varies from 1,312 to 4,593 feet (400 to 1,400 meters).
