Venezuelan Oil and the Limits of U.S. Refining Capacity


Last week, U.S. President Donald Trump’s Venezuela pitch to oil executives to invest the vast sums required to revive the country’s flagging oil sector proved largely ineffectual. Exxon Mobil (NYSE:XOM) CEO Darren Woods offered the starkest assessment, calling the South American country “uninvestable” under its current commercial frameworks and hydrocarbon laws, while ConocoPhillips (NYSE:COP) CEO Ryan Lance also gave Trump a reality check, informing him his company lost billions of dollars when it exited the country under the Chavez regime.

The serious descent of Venezuela’s energy sector into the abyss began after Hugo Chávez’s government nationalized the oil infrastructure and assets of ExxonMobil (NYSE:XOM) and ConocoPhillips (NYSE:COP) in 2007, after the companies refused to accept new terms that would give the Venezuelan state oil company, PDVSA, a majority share in their projects. The nationalization process was initiated in early 2007 through a presidential decree and a new Hydrocarbons Law.

Trump, however, scored some notable wins. To wit, Hilcorp‘s Jeff Hildebrand said his company is ready to go rebuild Venezuela’s energy infrastructure, while Chevron (NYSE:CVX) said it can ramp up its Venezuela production of 240K bbl/day “100% essentially effective immediately”.

Previously, we reported that it will take billions in infrastructure investments to return Venezuela’s oil sector to its 1970s peak production of 3.5 million barrels per day. Venezuela currently produces ~1 million barrels per day, with Chevron accounting for a quarter of that. U.S. refiners love Venezuelan crude because it provides a competitive advantage for complex refiners with substantial coking capacity that can process the heavy oil into high-value products. Merey crude from Venezuela’s Orinoco belt has among the lowest in API gravity and highest sulfur content globally, requiring specialized refinery units to break down the heaviest molecules and remove impurities.

Unfortunately, less than half of U.S. refineries have a coker, with refiners along the Gulf and East Coasts most likely to benefit from higher Venezuelan crude supplies. U.S. refiners with the highest coking capacity include Valero (NYSE:VLO), Exxon, Chevron, Marathon Petroleum (NYSE:MPC), Phillips 66 (NYSE:PSX) and PBF Energy (NYSE:PBF). 

Coking and hydrocracking are petroleum refining processes that upgrade heavy crude oil fractions into lighter, more valuable products like gasoline, diesel, and jet fuel, but they use different methods: Coking is a thermal, carbon-rejection process, essentially baking heavy oil to leave solid petroleum coke and lighter liquids. Hydrocracking uses high-pressure hydrogen and a catalyst to chemically add hydrogen, breaking large molecules into smaller ones, producing cleaner fuels with fewer solid byproducts. Highly complex refiners can achieve distillate yields of 33% compared to 30% for medium-complexity plants. Shortages of heavy oils like Venezuelan crude have forced many U.S. refineries to invest in topping units to refine lighter oils such as U.S. shale oil.
