Chevron, the only U.S. oil company currently active in Venezuela, operates a high-capacity refinery in Pascagoula, Mississippi capable of processing 369,000 barrels per day of heavy crude. Chevron also operates two refineries in El Segundo and Richmond, California configured to process heavy crude oil with capacity of 515,000 barrels per day.

Venezuelan crude oil worth $2.8 billion could reach Texas refineries next week following Trump's announcement of 50 million barrels heading to Gulf Coast.
