Venezuelan oil is more about US refineries that can only use very heavy oil, and US wells for such oil running out. Those refineries decided it is cheaper to bribe Trump than to invest into converting their factories. They are using US tax payer dolars (in a war with Venezuela) to avoid having to invest into their own conpanies.

That makes no sense. Any US refinery that can process heavy sour can also process any other kind of crude. It isn’t the 1950s.

The US has very advanced refinery tech that can adaptively refine everything from heavy sour to light sweet. The reconfiguration for the customer is highly customizable and largely automated. It is why so many countries send their crude to the US for refining. The US refiners make money no what kind of crude you send them.

Yet this is yet another attack that happens while the oil price falls, successfully making it stop falling.

Again, I don't think the explanation is linked to oil prices.
