Shell Serrano Oregano

Shell Serrano Oregano

U.S., Gulf of Mexico Blocks GB 472 & 516 and 558 & 559

Landmark: The world’s first electric-heated flowlines to prevent hydrate formations debut in the Gulf of Mexico.  

The Oregano field is located in the Gulf of Mexico at Garden Banks 559, and the Serrano field is located in the Gulf of Mexico at Garden Banks 516. The Oregano and Serrano projects were developed together as one project to take advantage of synergies in design and execution. The Oregano field is approximately 8 miles (13 km) south of the Auger TLP, and the Serrano field is 6.5 miles (11 km) southwest of the Auger TLP.

The Oregano field was developed using subsea wells tied into a PLEM (pipeline end manifold). Hydrocarbons from both wells are commingled to the PLEM and flowed back to Auger TLP through a single electric-heated pipe-inpipe (EHPIP) pipeline and riser. The Serrano field was developed using the same tree and PLEM system as Oregano. Individual wells were completed using FMC’s SDDSI standardized subsea tree system. Production is routed from the trees to the PLEM via 4" nominal 410 SS jumpers.
