Petrobras Starts Up Production at Cascade Field
Petrobras reported that on February 25, 2012, it was started the production of Cascade field through Cascade 4 well, interconnected to FPSO (Floating, Production, Storage and Offloading unit) BW Pioneer, located approximately 155 miles (250 kilometers) off the coast of Louisiana State, in a 8,202 feet (2,500 meters) water depth in the U.S. Gulf of Mexico.
The Cascade 4 production well was drilled and completed in reservoirs of the Lower Tertiary geological period, which is a promising exploratory maritime boundary of the Gulf of Mexico, at a vertical depth of around 26,247 feet (8,000 meters).
The BW Pioneer is the first FPSO to produce oil and gas in the U.S. portion of the Gulf of Mexico, and has the capacity to process 80 thousand barrels of oil and 500 thousand cubic meters of gas per day. The vessel is provided of a disconnecting anchorage system which allows its displacement to sheltered areas in the event of a storm or hurricanes. Petrobras is the first company to develop an oil field in the Gulf of Mexico using a FPSO, which has already been successfully and systematically employed in Brazil.
