Shell Family

As a member of the community, we take great pride in being a part of the economic engine that helps to keep Ascension Parish growing. Being a good neighbor in the community is not just running a business. We take an active part in our education system and also spend time doing volunteer work in our community to help those in need. We believe that our people are our most valuable asset.

Shell Chemicals - With major manufacturing facilities around the world, the companies that make up Shell Chemicals number among the world's largest petrochemical operations. We focus on the production of bulk petrochemicals and their delivery to large industrial customers who, in turn, use them to make many of the essential materials of our modern world.

Shell Chemical LP -The Shell Group’s chemical business operations in the U.S. are performed through Shell Chemical LP, which is one of nearly 70 companies engaged in chemicals businesses for the Shell Group.

Geismar plant

Our Plant 

The Plant is located on the east bank of the Mississippi River, 20 miles downriver from Baton Rouge, Louisiana.

On January 18, 1965 Shell announced the purchase of the Geismar site. The original site was about 700 acres and was formerly part of Ashland - Belle Helene Plantation. By mid-1966, the construction was in full swing. Offices were moved to the plant site in February, 1967 from a leased location at 721 Government Street in Baton Rouge.

The Shell Geismar facility manufactures Detergent Alcohols, Ethylene Glycol, Alpha Olefins, and a diversified line of ethylene based industrial chemicals used in a wide range of modern applications.

The Shell Geismar Plant site currently contains approximately 800 acres of which only 400 acres are developed. The site has 530 employees and a varying number of contractors. We take great pride in the fact that our PEOPLE are our most valuable asset and SAFETY is our number ONE product.


  • Alpha Olefins - Alpha olefins are used to make high-performance synthetic lubricants, biodegradable detergents, drilling fluids, and as co-monomers to make stronger, lighter polyethylene film.
  • Ethylene Glycols - used to make soft drink bottles and containers.  Also used to produce polyester fibers with aid in the production of clothes, upholstery, carpet, pillows, and surgical supplies.  Some Ethylene Glycol is used in the production of antifreeze and heat transfer fluids.

Our team is rigorously trained and highly professional.
