In 1946, as part of the purchase of Rock Island Oil and Refining Co., Wood River Oil Co. (a pre-cursor company to Koch Industries) acquired a small crude oil pipeline in southwestern Oklahoma. The Wood River Oil Co. also constructed a new pipeline to supply product to its St. Louis refinery. In the late ‘50s, other investments brought pipelines in the Northern Midwest and Canada under the company’s operation.

In the ensuing years, the company bought, sold and built pipeline systems transporting crude oil and refined products, as well as natural gas, natural gas liquids and anhydrous ammonia (for fertilizer). Today, Koch Pipeline and its affiliates keep a 4,000-mile network of pipelines running efficiently and safely, supplying modern conveniences necessary for everyday life.
