This seems like a much bigger deal than the news has portrayed. It seems like Trump feels like he can't do fun things (bomb Iran) because of the oil stockpile. So he is doing anything he can to try to show markets that he has oil so he can get back to doing fun.
However, "The bulk of the country’s petroleum is made up of heavy, sour crude oil—a dark, gloopy, acidic substance that is both high in sulfur and relatively difficult to recover. This type of crude oil is very useful in asphalt production, but it needs to undergo a longer refining process to be made into more lucrative products, such as gasoline and other fuels, compared with lighter crude oil" https://www.britannica.com/science/How-Much-Oil-Does-Venezuela-Have-and-How-Much-Is-Accessible
