Our refineries and retail stores are concentrated in the south and southwest United States. The reach of our operations, however, extends throughout the country through our network of logistics hubs and refined product marketing business, and continues to expand with our growing operations.
Our four inland refineries serve local markets around them as well as various regional markets, including portions of Mexico, through our logistics network and select third-party pipelines.
Our refinery system sources approximately 70% of its crude oil from the Permian Basin, via a combination of third-party and Delek pipelines. To make the most of our access to the Permian Basin, we are expanding our Big Spring crude oil gathering operations focused in this area.
