Kendra Pierre-Louis: For Scientific American’s Science Shortly, I’m Kendra Pierre-Louis, in for Rachel Feltman.
Over the previous couple of weeks oil—particularly, Venezuelan oil—has been everywhere in the headlines.
It began late on January 2, when President Donald Trump ordered U.S. army forces to enter Venezuela and seize the nation’s president, Nicolás Maduro, which they did early the subsequent morning. Final week the nation’s inside minister mentioned the motion killed 100 folks.

Within the intervening weeks President Trump has made clear that at the very least a part of his motivation for the operation was the nation’s oil fields, that are house to an estimated 303 billion barrels of oil reserves, extra oil than Saudi Arabia or some other nation on the earth.
To dig into the scenario we spoke with Amy Westervelt, a local weather reporter and govt editor of the multimedia local weather reporting challenge Drilled. We talked to Amy about why Venezuela has a lot oil, the historical past of the nation’s oil trade and the way this obsession with oil is impacting local weather change.
Thanks for becoming a member of us.
Amy Westervelt: Thanks for having me.
Pierre-Louis: You maybe know extra about oil in South America than some other local weather reporter I’ve met. What acquired you curious about it?
Westervelt: Truly, Guyana is what acquired me [Laughs] all in favour of it. So I acquired this press launch from Exxon[Mobil] in, I wanna say, 2020 that mentioned that Guyana was going to be their best basin inside the subsequent 5 to 10 years, that it might outpace even the Permian Basin in Texas. And I assumed, “How did they go that massive that quick?”
After which shortly after that I acquired some press releases from an lawyer that had filed numerous instances in Guyana making an attempt to cease the offshore challenge and arguing that a part of the rationale that they’d moved so quick was that they’d ignored numerous environmental rules.
So these two issues form of got here in the identical week, and I assumed, “Oh, that is actually fascinating, and I haven’t actually seen a lot about it.” So I began working with a reporter in Guyana after which going backwards and forwards myself to report on this, like, new oil trade that was being created in, you already know, 2020.
Pierre-Louis: Okay, we are going to get again to Guyana, I promise.
Westervelt: [Laughs.]
Pierre-Louis: However earlier than we get there …
Westervelt: Yeah.
Pierre-Louis: As you already know the Trump administration not too long ago invaded Venezuela and captured its president, Nicolás Maduro, below allegations of drug trafficking. Your latest article in Drilled mentions entry to the area’s oil is a giant motivator of what’s taking place there. And form of focusing primarily simply on Venezuela for proper now, Venezuela has quite a lot of oil, like, an estimated 303 billion barrels of oil, in comparison with the USA, which has roughly 46 billion barrels. A really primary query: Like, why does Venezuela and that space simply have a lot oil?
Westervelt: Effectively, they’ve the Orinoco Basin, which is the world’s largest oil reserve, principally [Laughs], so Venezuela has essentially the most oil of anybody on the earth. However it’s not nice oil; it’s heavy crude. And so it’s form of on par with, like, tar sands oil in Canada.
Pierre-Louis: So what does that imply? As a result of I believe for most individuals …
Westervelt: Proper.
Pierre-Louis: We don’t actually take into consideration, like, grade of oil. We don’t usually see oil. If now we have a imaginative and prescient of what oil is, it’s like The Beverly Hillbillies …
Westervelt: [Laughs.] Sure.
Pierre-Louis: And, like, it, like, trickling out of the bottom. [Laughs.] So, so what do, like, grades of oil really imply?
Westervelt: So the Venezuelan oil is heavy crude, which suggests it’s acquired quite a lot of stuff in it, which signifies that it’s dearer to refine, which cuts into oil corporations’ margins. And it is also much less favorable for lots of various, like, sorts of engines, sorts of makes use of, which signifies that it will get a lower cost available on the market.
In order the worth of oil has come down the worth of heavy crude comes down much more as a result of what we usually consider as, like, the worth per barrel is good crude, you already know? [Laughs.] It’s, like, it’s the good things. So no matter that’s at, which is decrease, heavy crude is gonna be even decrease than that. After which on prime of that Venezuelan oil has had all these sanctions in opposition to it. Trump has been a part of that, each in his first time period and extra not too long ago.
So, you already know—’trigger I really feel just like the query is all the time like, “Why isn’t Venezuela Saudi Arabia, proper [Laughs], like, if it has this a lot oil?” And there are a number of causes, one in all which is, yeah, the standard of oil, the gap to markets for it after which the truth that it has sanctions on these markets.
Extra individuals are extra within the stuff that doesn’t burn fairly so heavy. Partly, that’s pushed by environmental rules as nicely.
However then on prime of that they’ve recognized they’d this oil for a very long time. I imply, some folks will say, like, the Spaniards knew it once they have been colonizing Venezuela and all of that, however for certain they’ve been growing it since round World Warfare I, when everybody was searching for extra oil as a result of that was the primary form of massive fossil fueled conflict.
And American corporations have been in there, like, just about since soar. So you’ve this bizarre factor that occurs in quite a lot of conditions the place U.S. oil corporations really feel, like, this attachment to the oil trade there [Laughs] and this, like, entitlement to the oil that’s there as nicely.
However, like, Venezuela began making an attempt to nationalize its oil trade in, like, the ’30s and ’40s. We discovered some paperwork from this outdated PR man who acquired despatched by Normal Oil to go attempt to, like, cease this from taking place within the ’40s and was profitable. And a giant a part of that was labor and, you already know, the truth that employees have been aggravated that, you already know, they have been being badly paid and badly handled by these overseas corporations that have been making a lot cash off of Venezuelan oil. So, you already know, at the moment, within the ’40s, it was all about form of, like, coping with the labor unions, eliminating the labor unions, getting contracts in place that, you already know, would stop that from taking place.
However they might solely form of stave it off for thus lengthy, and in 1976 Venezuela did nationalize oil, however they allowed quite a lot of joint partnerships, so it didn’t actually overly have an effect on U.S. oil corporations [Laughs]—till [then-Venezuelan President Hugo] Chávez in 2007 mentioned, “Okay, sufficient of this. Like, you could be right here, however the majority shareholder in any oil challenge in Venezuela needs to be the state oil firm. And for those who don’t prefer it, like, you will get out.” And each Exxon and ConocoPhillips refused.
And they also left, and he seized their property. Chevron stayed as, like, a minority shareholder in among the tasks there, however that has been, you already know, form of up and down in recent times due to U.S. sanctions as nicely, so Chevron’s form of been teetering. However when Exxon acquired kicked out they’d this backup plan already in thoughts ’trigger they’d been tenting out on an exploratory license in Guyana because the late ’90s.
Pierre-Louis: Yeah, and so my understanding is way of that infrastructure that Venezuela had is now fairly outdated. And so simply to summarize form of the lay of the land: Venezuela has oil, however a lot of it isn’t that nice, and it might want important infrastructure funding to actually get it pumping once more to the diploma that we appear to be speaking about, and it wouldn’t essentially command an important value.
Westervelt: To the tune of, like, tens of billions of {dollars}. Like, it’s not a small sum of money that we’re speaking about right here.
Pierre-Louis: And but proper throughout the border is Guyana, which has a ton of candy, mild crude. Are you able to speak in regards to the battle that has been taking part in out over the previous few years between Venezuela and Guyana?
Westervelt: Sure, in order that battle really goes again all the best way to, like, the late 1800s. So Venezuela and Guyana have argued over this one space that’s referred to as Essequibo. Venezuela has claimed that it’s a Venezuelan state for a very long time. Within the late Nineties—I believe it’s 1899—there was a global arbitration ruling over this dispute that mentioned, “No, that is the place the border is. Essequibo is in Guyana.” And that, you already know, was form of tremendous for some time period.
Within the early ’60s this dispute form of, like, got here up once more. Some folks assume, really, it was round oil then as nicely ’trigger there was some early exploration taking place and a few pondering that probably there was oil off the coast there. And at the moment there was one other treaty that was signed that’s referred to as the Geneva [Agreement], and it was signed by the U.Okay., Venezuela and British Guiana, which is what Guyana was on the time as a result of it had not been given …
Pierre-Louis: Independence.
Westervelt: Independence but, precisely. So it was signed, made official in 1966, after which simply, really, like, a number of months later Guyana was simply form of added to it. Like, they have been, like, made unbiased, so it’s like, “Oh, now it’s you guys,” however they by no means actually, like, agreed to any of these things.
So in 2015 Exxon introduced that they’d discovered this monumental reserve of oil offshore Guyana. And instantly, Maduro began saying, “You realize, really, that’s Venezuela.” I talked to some petroleum engineers in Guyana, and a few of them really assume that a part of the rationale Venezuela was involved in regards to the oil in Guyana was additionally that they assume the reservoirs are linked, and they also have been involved that if the oil’s getting taken out, like, over right here, it might scale back manufacturing in Venezuela as nicely.
However regardless, this complete dispute has flared up once more since 2015. And within the final two years particularly Maduro began to get actually aggressive about it. And that is the piece that I really feel like has been missed by quite a lot of the protection round Venezuela, is that, you already know, he began sending, like, navy ships to, like, patrol round this space.
[Laughs.] In December of 2023 Maduro simply, like, as soon as once more declared that Essequibo is a Venezuelan state. He had a referendum the place the folks of Venezuela voted, and, you already know, the voting system in Venezuela has been below quite a lot of scrutiny for numerous causes [Laughs] for a very long time, however he claims that Venezuelan voters overwhelmingly agreed that that is a part of Venezuela. After which in January 2025 he introduced that they might be holding elections for the governor of this Venezuelan state.
As this is occurring Guyana has now taken a declare to the Worldwide Court docket of Justice to ask them to rule on it. They’ve filed that declare in 2018. It’s been very slow-moving. However, like, the ruling has thus far mentioned, “Hey, you guys need to, like, preserve the established order till we make a remaining determination,” which hasn’t occurred but.
However then in March of 2025 Venezuela despatched [naval ship] to Exxon’s floating offshore manufacturing vessel [Laughs] and informed employees of that boat that they have been in Venezuelan waters, you already know, have been, like, aggressively asking a bunch of questions. It was a really aggressive act, and it was instantly at Exxon’s vessel, and that actually acquired the U.S. concerned. So abruptly each the U.S. State Division form of issued an announcement about it—there have been, like, numerous entities that have been saying, like, “Hey, you guys can’t do that. It’s essential calm it down.”
After which Marco Rubio really went to Venezuela in late March of 2025 and gave this press convention with Guyanese officers, the place he mentioned, like, “Venezuela’s gonna have the U.S. army to take care of if it doesn’t calm it down with these things.”
Pierre-Louis: So undergirding all of this jockeying for oil is the truth that the planet is getting hotter …
Westervelt: [Laughs.] Proper.
Pierre-Louis: Local weather change is actual …
Westervelt: Proper, yeah, uh-huh.
Pierre-Louis: And the fact is that if we wanna keep circumstances which are appropriate for human life, we have to cease utilizing oil and fossil fuels altogether. It very a lot looks like we’re in [an] early 2000s redux, however the local weather is way hotter. [Laughs.]
Westervelt: Yeah, it’s a lot worse. I imply, this, really, to me, was additionally what drew me to the Guyana story within the first place, is that [roughly] 90 p.c of the inhabitants of Guyana is on this tiny sliver of coast proper subsequent to Georgetown that shall be underwater in about 10 years.
Pierre-Louis: That’s stunning.
Westervelt: [Roughly] 90 p.c of the inhabitants wants to maneuver and but they have been going all in on this new oil trade. I used to be like, “What? What? Make it make sense.”
However the unhappy—to me, it’s, like, such an illustration of the entire failure of the worldwide neighborhood to do something about this downside, to determine, you already know, any form of local weather damages or reparations coverage. As a result of Guyana, which was additionally, like, the early poster little one for paying growing nations for carbon sinks and dealing with the World South on carbon credit and all of that stuff: like, they have been—you already know, Norway put a bunch of cash into preserving forests in Guyana for the aim of sustaining a carbon sink there. They’re one of many world’s largest carbon sinks nonetheless. They have been like, “We will’t pay to maneuver our complete nation away [Laughs] from sea-level rise with out this oil cash.” So it’s, like, the most important “robbing Peter to pay Paul” story I’ve ever heard of, and it’s simply—it’s mind-blowing that, like, they’re now on the mercy of oil corporations to pay for local weather adaptation.
Pierre-Louis: That’s actually tragic, if you consider it.
Westervelt: It’s completely tragic, yeah.
Pierre-Louis: From a local weather perspective, what do you assume is lacking from the dialog round Venezuela and Guyana?
Westervelt: Effectively, I imply, I believe the local weather in its entirety is lacking from that dialog. I really feel like the truth that each of those nations are going to be massively hit by local weather impacts is, like—it’s virtually solely lacking. Even, you already know, Guyana’s form of saying, like, “Oh, nicely, you already know, if now we have all this oil cash, then we will pay to, like, transfer everybody out of hurt’s method.” Effectively, the place is out of hurt’s method?
What occurs if there’s a blowout? Effectively, all of the Caribbean will get impacted by that. You’ve got an oil spill that hits—I imply, Exxon’s personal environmental impression report on this reveals that if such a factor have been to occur, it might impression 14 completely different Caribbean nations, 14, and all of that are at the very least considerably depending on tourism …
Pierre-Louis: Mm-hmm.
Westervelt: For his or her financial system, so as soon as these seashores are destroyed by an oil spill, how’s that gonna go? To not point out, like, meals supply …
Pierre-Louis: Yeah, fishing …
Westervelt: [Laughs.] Fishing.
Pierre-Louis: Is massive within the Caribbean.
Westervelt: Precisely. So there’s so many layers of issues right here.
And once more, I simply really feel like—once I talked to folks in Guyana, too, about, “What’s happening right here? Aren’t you guys—I assumed you guys have been so involved in regards to the setting [Laughs] and local weather and no matter,” they’re like, “Yeah, we’re, however, like, how are we gonna pay for all of these things?” And so they have been, like, a bit of bit—and I don’t assume they’re incorrect on this—“Effectively, what’s the distinction between taking cash from the Norwegian authorities to maintain our timber [and] taking cash from Exxon to drill our oil?”
Pierre-Louis: Proper, nicely, this has been—I gained’t say a beautiful dialog, nevertheless it has been …
Westervelt: [Laughs.]
Pierre-Louis: [Laughs.] An illuminating dialog …
Westervelt: Yeah.
Pierre-Louis: Thanks a lot in your time as we speak.
Westervelt: Thanks. Thanks for having me.
