Roncador oil field
The Roncador oil field is an oil and gas field discovered in 1996 in the Brazilian sea area of Campos Basin in the South Atlantic . Roncador is located around 125 km off the coast of Brazil, northeast of Rio de Janeiro . In 1998 the oil reserves were estimated at 2.7 billion barrels . In 2000 the first large production system was installed in the Roncador oil field.
The field covers an area of around 28,000 hectares and reaches extraction depths of up to 1900 meters. The operator is Petrobras (NOC), which currently (as of mid-2013) has five drilling rigs and special production facilities there. Due to its size and different conveying density, the Roncador field was divided into four sections, which are referred to as modules 1 to 4.
advancement
Production in the Roncador field began in January 1999 with the Petrobras 36 platform. In the early hours of the morning of March 15, 2001, a Thursday, two explosions occurred on the starboard aft pillars for reasons that are not clear. Immediately afterwards, the P-36 inclined 16 degrees and later 25 degrees, so that large areas of the platform came under water and this could penetrate. Of the 175 crew members at that time, 11. There were 1,500 tons of crude oil on board, and due to fears of an oil spill, the authorities coordinated a major emergency operation. Petrobras 36 sank to a depth of 1,300 meters on the morning of March 20. In this first phase, 20,000 barrels of oil were produced daily.
The originally recoverable reserves are stated by Petrobras at 3 billion barrels. It is currently being produced with 59 drilling rigs, and another 29 rigs are pumping water into the field to increase the oil yield. Petrobras estimates the cost of operating the oil field at about $ 2.2 billion. The field produces 460,000 barrels per day, which is estimated to be near the production peak.
