RIO DE JANEIRO – Petróleo Brasileiro S.A. has started producing the deepwater Cascade field in the Gulf of Mexico. The Cascade 4 well is flowing into the FPSO BW Pioneer in 2,500 m (8,202 ft) water depth 250 km (155 mi) offshore Louisiana.
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 80,000 b/d of oil and 500,000 cm/d (1.766 MMcf/d) of gas per day.
This well is connected to the vessel by subsea equipment and lines, in addition to free-standing risers (vertical production lines). The oil will be transported ashore by shuttle tanker, and the gas through pipelines.
The vessel has a detachable mooring system that allows it to sail to sheltered areas when weather conditions dictate.
