Shell Deer Park Complex Org Chart
Last reviewed: 2026-05-01
The Deer Park complex in Deer Park, Texas includes a refinery now owned and operated by Pemex (acquired from Shell in 2023) and Shell chemical manufacturing operations that continue under Shell ownership. The refinery has approximately 340,000 barrels per day of capacity. The chemical plant produces ethylene, propylene, and various derivatives. Maintenance, operations, and procurement are now managed separately by the two owners, though the facilities share infrastructure. Vendors should engage each entity independently for qualification.
Key Facts
Site Overview
The Deer Park complex sits along the Houston Ship Channel in Deer Park, Texas. The refinery was sold by Shell to Pemex in January 2023 and now operates under Pemex management. Shell retains ownership and operation of the adjacent chemical manufacturing facilities. The complex has been a major Ship Channel fixture since the 1920s.
Refinery Operations (Pemex)
The Deer Park refinery, now under Pemex management, has approximately 340,000 barrels per day of capacity. The acquisition brought organizational changes as Pemex implemented its own management structure. Maintenance and operations leadership now reports through Pemex's organizational framework, though many experienced personnel from the Shell era remain at the site.
Chemical Operations (Shell)
Shell continues to operate the chemical manufacturing facilities at Deer Park, producing ethylene, propylene, and specialty chemicals. The chemical plant maintains Shell's organizational structure with maintenance, engineering, and procurement functions reporting through Shell Chemicals leadership. Shell's global procurement organization supports the site.
Vendor Considerations
Vendors serving the Deer Park complex must now navigate two separate organizations. The refinery side requires Pemex vendor qualification, while the chemical plant side follows Shell's corporate procurement process. Infrastructure sharing between the two operations creates some coordination requirements, but purchasing and contractor management are handled independently.
