Most major oil companies are unwilling to touch Venezuelen oil with a proverbial bargepole. Not so Chevron.
America's second largest oil company has been in Venezuela since 1923, navigating or conveniently ignoring all of the many varieties of bad stuff that have happened there over the decades. Now, in response to Donald Trump's call for private development of the mess that is Venezuela's oil industry, Chevron is the only US oil company to step forward, not back.
The other companies, preferring not to be associated with Venezuela, are eschewing the country for sound financial reasons: most analysts think it will take many years of serious investment before Venezuelan oil will be profitable for them. Plus, the US government is insisting on taking a 20% cut (finders fee?)
But you have to think too that they are all too conscious of the reputational risk involved. After all, the US's involvement arose through an invasion. Trump would have us call it a "deal", because everything is a deal to him. But the reality is, America invaded Venezuela, kidnapped its elected leader (who is even now languishing in an American jail), and intimated and browbeat the interim government into granting the US de facto control over its huge oil reserves.
This, then, is blood money, spoils of war. Most sensible companies would want to distance themselves from that. But Chevron? They're all in. Now, you might want to boycott Chevron-owned gas stations: Chevron, Texaco, Caltex. I don't know whether that is already an ongoing campaign, but if it isn't, it should be. Me, I have an electric car, otherwise I would be there too.
