President Donald Trump's plan to take control of Venezuela's oil industry and ask American companies to revitalize it after capturing President Nicolás Maduro in a raid isn't likely to have a significant immediate impact on oil prices.

Venezuela's oil industry is in disrepair after years of neglect and international sanctions, so it could take years and major investments before production can increase dramatically. But some analysts are optimistic that Venezuela could double or triple its current output of about 1.1 million barrels of oil a day to return to historic levels fairly quickly.

“While many are reporting Venezuela’s oil infrastructure was unharmed by U.S. military actions, it has been decaying for many many years and will take time to rebuild,” said Patrick De Haan, who is the lead petroleum analyst at gasoline price tracker GasBuddy.

American oil companies will want a stable regime in the country before they are willing to invest heavily, and the political picture remained uncertain Saturday with Trump saying that the United States is in charge — while the current Venezuelan vice president argued, before Venezuela’s high court ordered her to assume the role of interim president, that Maduro should be restored to power.

“But if it seems like the U.S. is successful in running the country for the next 24 hours, I would say there would be a lot of optimism that U.S. energy companies could come in and revitalize the Venezuelan oil industry fairly quickly,” said Phil Flynn, a senior market analyst at the Price Futures Group.

And if Venezuela can grow into an oil production powerhouse, Flynn said “that could cement lower prices for the longer term” and put more pressure on Russia.

The price of U.S. crude oil fell .44% to $57.07 per barrel on Sunday evening. A major shift in oil prices wasn't expected because Venezuela is a member of OPEC, so its production is already accounted for there. And there is currently a surplus of oil on the global market.

Proven reserves

Venezuela is known to have the world's largest proven crude oil reserves of approximately 303 billion barrels, according to the U.S. Energy Information Administration. That accounts for roughly 17% of all global oil reserves.

So international oil companies have reason to be interested in Venezuela. Exxon Mobil didn’t immediately respond to a request for comment Saturday. ConocoPhillips spokesperson Dennis Nuss said by email that the company “is monitoring developments in Venezuela and their potential implications for global energy supply and stability. It would be premature to speculate on any future business activities or investments.”

Chevron is the only one with significant operations in Venezuela, where it produces about 250,000 barrels a day. Chevron, which first invested in Venezuela in the 1920s, does business in the country through joint ventures with the state-owned company Petróleos de Venezuela S.A., commonly known as PDVSA.

“Chevron remains focused on the safety and wellbeing of our employees, as well as the integrity of our assets. We continue to operate in full compliance with all relevant laws and regulations,” Chevron spokesman Bill Turenne said.

But even with those massive reserves, Venezuela has been producing less than 1% of the world's crude oil supply. Corruption, mismanagement and U.S. economic sanctions saw production steadily decline from the 3.5 million barrels per day pumped in 1999 to today's levels.

The problem isn't finding the oil. It's a question of the political environment and whether companies can count on the government to live up to their contracts. Back in 2007, then President Hugo Chávez nationalized much of the oil production and forced major players like ExxonMobil and ConocoPhillips out.

“The issue is not just that the infrastructure is in bad shape, but it’s mostly about how do you get foreign companies to start pouring money in before they have a clear perspective on the political stability, the contract situation and the like,” said Francisco Monaldi, who is the director of the Latin American energy program at Rice University.

But the infrastructure does need significant investment.

“The estimate is that in order for Venezuela to increase from one million barrels per day — that is what it produces today — to four million barrels, it will take about a decade and about a hundred billion dollars of investment,” Monaldi said.

Strong demand

Venezuela produces the kind of heavy crude oil that's needed for diesel fuel, asphalt and other fuels for heavy equipment. Diesel is in short supply around the world because of the sanctions on oil from Venezuela and Russia and because America's lighter crude oil can't easily replace it.

Years ago, American refineries on the Gulf Coast were optimized to handle that kind of heavy crude at a time when U.S. oil production was falling and Venezuelan and Mexican crude was plentiful. So refineries would love to have more access to Venezuela's crude because it would help them operate more efficiently, and it tends to be a little cheaper.

Boosting Venezuelan production could also make it easier to put pressure on Russia because Europe and the rest of the world could get more of the diesel and heavy oil they need from Venezuela and stop buying from Russia.

“There’s been a big benefit for Russia to see Venezuela’s oil industry collapse. And the reason is because they were a competitor on the global stage for that oil market,” Flynn said.

Complicated legal picture

But Matthew Waxman, a Columbia University law professor who was a national security official in the George W. Bush administration, said seizing control of Venezuela’s resources opens up additional legal issues.

“For example, a big issue will be who really owns Venezuela’s oil?” Waxman wrote in an email. “An occupying military power can’t enrich itself by taking another state’s resources, but the Trump administration will probably claim that the Venezuelan government never rightfully held them.”

But Waxman, who served in the State and Defense departments and on the National Security Council under Bush, noted that “we’ve seen the administration talk very dismissively about international law when it comes to Venezuela.”
