Question · Q3 2025
Phillip Jungwirth asked about Marathon Petroleum's planned crude slate for the Gulf Coast and Midcon, noting an expected higher percentage of sweet crude in Q4, and inquired about market observations for sourcing advantaged barrels. He also asked about the availability of dock space for waterborne refined product imports into California, and if it poses a bottleneck to future supply given refinery closures.
Answer
CCO Rick Hessling explained that GBR is advantaged to run sweet discounted crude due to its location, while Garyville toggles between sweet and sour based on economics, noting increasing looks at Iraqi barrels. He also mentioned running discounted Canadian heavy barrels. On California dock space, Rick Hessling confirmed it is a significant deterrent and headwind for waterborne imports, citing fog, delays, unexpected incidents, and high freight rates as factors that make waterborne supply less reliable than in-state refining, creating tailwinds for MPC.
