Calcasieu Refining Co.

Located along West Tank Farm Road in the industrial corridor of Lake Charles, Calcasieu Refining Co. operates an oil refinery that processes crude oil into a range of finished petroleum products. The facility produces fuels and heating oils, placing it within the downstream segment of the oil and gas industry — a sector with deep roots in Southwest Louisiana's economic landscape.

The refinery functions as a manufacturer within the regional energy supply chain, converting raw crude into products that serve commercial and industrial end users. West Tank Farm Road sits within a concentrated zone of petrochemical and energy infrastructure near Lake Charles, making the location well-suited to the logistical demands of refining operations, including feedstock delivery and product distribution.

With a reported revenue in the range of ten million dollars, the company represents a mid-scale independent refining operation in a region dominated by much larger petrochemical complexes. For businesses and buyers operating within the fuels and heating oil markets across the Lake Charles area and beyond, Calcasieu Refining occupies a distinct niche as an independent processor in a landscape otherwise shaped by major integrated energy corporations.
