The world is still processing the nighttime raid on Venezuela by U.S. forces on Saturday, capturing President Nicolás Maduro and his wife, and flying them to New York to face narcoterrorism and drug conspiracy charges. President Trump stated the U.S. would run Venezuela until a transition could happen, aiming to access its oil.
Venezuela holds the world’s largest proven oil reserves at 303 billion barrels, but because it is mostly extra-heavy crude, it requires specialized refining. While the potential reopening of the Venezuelan oil market presents opportunities for major integrated oil firms, Louisiana’s Gulf Coast — home to six of the largest heavy crude refineries in the world — means it will likely see large inflows of any oil from Venezuela. The primary beneficiary, however, could be Marathon Petroleum (NYSE:MPC | MPC Price Prediction), the operator of the state’s largest heavy crude facility.
Why Heavy Crude Needs Advanced Refining
Venezuela’s oil is predominantly heavy and extra-heavy crude from the Orinoco Belt, which is thicker, denser, and higher in sulfur than lighter varieties. This makes it cheaper to buy but requires complex, high-capacity refineries — such as cokers and hydrocrackers — to profitably convert it into valuable products like gasoline, diesel, and jet fuel.
Louisiana is the ideal destination for this oil. Located on the Gulf of America, the state hosts 15 refineries with over 3 million barrels per day (bpd) of capacity — about 17% of the U.S. total — and many are specifically built for heavy sour crudes. Key facilities include:
- Marathon Petroleum’s Garyville (with capacity for 606,000 bpd)
- ExxonMobil‘s (NYSE:XOM) Baton Rouge (522,000 bpd)
- Citgo‘s Lake Charles (455,000 bpd)
These rank among the world’s largest heavy crude processors. Moreover, its proximity to deepwater ports, the Louisiana Offshore Oil Port (LOOP), Mississippi River access, and extensive pipelines make importing and distributing Venezuelan heavy crude efficient and cost-effective.
With U.S. oversight potentially restoring Venezuelan production toward 3 million bpd, Gulf Coast refineries — especially those in Louisiana — are poised to handle the increased heavy flows for diesel, asphalt, and other high-demand products.
Marathon Petroleum’s Position and Outlook
Marathon Petroleum’s Garyville refinery is Louisiana’s largest and is configured for heavy sour crudes, producing gasoline, distillates, asphalt, and propane. Because U.S. oversight of Venezuela’s oil industry could increase heavy crude flows, the refining and marketing giant may be able to continue running at high utilization — crude capacity utilization was at 95% in the third quarter — and capture more refining and marketing margins.
Third-quarter results missed analyst expectations overall, but the refining and marketing segment remained strong, generating $3.2 billion in adjusted EBITDA due to Marathon’s efficient operations and improved market conditions. Refining margins rose to $17.60 per barrel, up sharply from $14.63 per barrel a year ago, but the company faced $400 million in turnaround costs — with the Q4 forecast expected to increase to $420 million — and a $99 million renewable diesel loss.
Still, with Venezuelan supply, Marathon could capture 20% to 30% of increased exports given its scale and location.
Key Takeaway
Certainly, Chevron (NYSE:CVX), Exxon, and Citgo will all benefit from Venezuelan crude, with Baton Rouge and Lake Charles refineries equipped for heavy processing. However, the scale of Marathon Petroleum’s Garyville facility positions it to gain the most.
With Marathon’s stock trading at less than 18 times earnings, 10 times estimates, and going for a fraction of its projected projected earnings growth rate, Marathon Petroleum offers better value than Exxon or Chevron, making it one of the more attractive oil stocks to buy on this still-developing situation.
