HOUSTON, Dec. 14>/b> -- Shell Exploration & Production Co. said Friday the Serrano subsea production system has been added to its Auger tension leg platform.
Serrano is the third subsea system to produce via Auger. Shell, the 100% owner of Serrano, began producing from its first well Dec. 1 and the second well Dec. 8.
The wells, on Garden Banks blocks 516 and 472 in the Gulf of Mexico, were producing 52.5 MMcfd of gas and 4,625 b/d of oil.
Serrano production is via a subsea flowline sled on Garden Banks 516, which is tied back 6 miles to Auger via a single production flowline.
Serrano is 220 miles southwest of New Orleans in 3,400 ft of water.
Auger's first subsea production system, Macaroni, began production in 1999. The second, Oregano, began production in October.
Serrano development costs are $120 million, excluding lease costs. Total recovery is estimated at 50 MMboe. Peak production will be 160 MMcfd of gas next year.
