In October, Venezuelan crude oil imports to the U.S. totaled approximately 4.2 million barrels, primarily benefiting refiners like Valero, PBF Energy, Chevron, and Phillips 66. These volumes, however, represent a small fraction of the refiners' overall supply, as they also import significant quantities from countries such as Mexico, Colombia, Brazil, Ecuador, Argentina, Guyana, and Saudi Arabia. Venezuelan crude's contribution remains minor compared to these alternative heavy-crude sources.
