Water Depth: 1,036 m
Start-up Year: December 2001
Located on Garden Banks Blocks 516 and 472, southeast of Houston and southwest of New Orleans, USA in 3,400 feet (1,036 metres) of water, the Serrano gas field is wholly owned and operated by Shell. Discovered in 1996 by the Ocean Worker, the field was further extended in 1999 by the Transocean Marianas. Development for the satellite field included a subsea system tied-back to the Auger TLP 6 miles (10 kilometres) away. Consisting of two subsea wells, the development utilizes a subsea flowline sled to transport gas and condensate to the Auger TLP. With estimated recoverable reserves of 50 MMboe, Serrano commenced production in 2005, peaking at 160 MMcf/d (4.5 MMcm/d) of natural gas in 2002. Auger TLP weighs 39,000 tons (35,380 tonnes) and is designed and engineered by Shell with a production capacity of 100,000 bopd and 300 MMcf/d (8.5 MMcm/d).
