How is oil transported to countries?

Oil is transported in four main ways. One of the most common ways to transport it is through the pipeline. Pipelines are one way it is transported when it goes over land, like the Alaskan pipeline that brought oil from Alaska down through Canada to the United States. That is usually the method used when transported across the land, but it requires digging up the land and areas sometimes don't like that such as when it passes through Indian Reservations and is protested like it was in the United States not so long ago.

Tankers are also used to transport oil. Sometimes that can be dangerous because they are so flammable. Rail cars, or trains, are also used to transport oil. That is an efficient way, economically but can still be dangerous. And then trucks also transport it. How oil is transported has a lot to do with where it is coming from and where it is going. If it's coming from the ocean, it is transported differently than when it comes from the land, which makes good sense.
