The Keystone Pipeline System spans 4,327 km (2,689 miles) and plays a key role in delivering Canadian and U.S. crude oil supplies to U.S. refining markets in Illinois, Oklahoma and Texas. Our footprint is uniquely positioned, providing unparalleled, enduring, and direct access to the largest refining markets in the Midwest and the Gulf Coast. Our network of pipelines safely transports 15% of the crude oil coming out of the world-class Western Canadian Sedimentary Basin (WCSB) and we have strategically located storage terminals in Canada and the U.S., including Hardisty, AB; Cushing, OK; and Houston/Port Arthur, TX.
