Shell Narco manufactureing complex

The Shell Norco Manufacturing Complex is located in Norco, Louisiana next to the Mississippi River, about 20 miles west of New Orleans in St. Charles Parish on nearly 1,000 acres of land.

Early history

In 1916, the New Orleans Refining Company purchased 366 acres of sugar cane field from the Goodhope Plantation to establish a marine petroleum supply terminal. In 1920, the New Orleans Refining Company began refining oil and thus the name of the town – Norco. The Shell Petroleum Corporation, a forerunner of Shell Oil Company, acquired the Norco Refinery in 1929. The chemical plant was added in 1955.

Recent history (post 1990 developments)

In 1998, a merger with Texaco and Saudi Aramco made the refining and chemical business officially separate; Shell Norco Refining Company became a division of Motiva Enterprises. In 2002, Texaco exited the merger and Motiva Enterprises became a 50/50 joint venture between Shell and Saudi Aramco. In 2004, the West Site Chemical Operations leased to Resolutions Performance (Hexion). The lease with Hexion ended and W.R. Grace is currently leasing a portion of the site. Following the Motiva joint venture separation, in May 2017, Shell assumed full ownership of the Norco Refinery.


Approximately 1200 employees staff the Shell Norco Manufacturing Complex. The workforce includes: Process Operators, Machinists, Instrument Mechanics, Electricians, Insulators, Pipefitters, Welders, Equipment Operators, Chemists, Engineers, Drafting, Financial, Environmental/Safety, Technology, Inspectors, Security, Administration, Training, Procurement, Human Resources and Communications professionals. In addition, there is a daily average of 1000+ contractors onsite to support the businesses.
