Actually all three methods are use depending on the type of oil and where it is.
Tanker cars. They'll fill up at a pipeline outlet, then be connected to a freight train which will deliver them to their destination.
The three most important modes of oil transportation from Mexico to the US include pipeline, oil tanker and railroad.
barrels are transported via tanker ships each year
Natural gas is transported through pipelines, which are typically made of steel and can run underground or underwater. Compressor stations are used along the pipelines to keep the gas moving. In some cases, natural gas can also be transported by tanker trucks or ships in its liquefied form (LNG).
Tanker trucks
The pipeline stops in Valdez Alaska. The oil then is put and an oil tanker and sent to Washington. Ever heard of the Exon Valdez? Pipeline oil.
In a fuel tanker specially built for that purpose.
The same way that gasoline gets from the refinery to the service station: it travels in refrigerated, stainless steel tanker trucks to packaging facilities (usually dairies) across the country where it is temporarily stored, packaged and distributed.
Petroleum is removed from the earth through a process called drilling. Wells are drilled into underground reservoirs of petroleum, and the oil is then pumped to the surface using a combination of pressure and extraction techniques. The extracted oil is then transported via pipelines or tanker trucks to refineries for processing.
Some common ways are to put a hole in an oil tanker ship, break an oil-carrying pipeline, overturn a a truck that carries or runs on an oil-based product, overturn a train for the same reasons, rust out an old bulk oil oil tank, turn the wrong valve at the oil refinery, and others.
Milk is usually transported in refrigerated tanker trucks to maintain its freshness and prevent spoilage. The milk is loaded into the tanker trucks at the dairy farm and delivered to processing plants or distribution centers where it is pasteurized, packaged, and distributed to stores for sale.
Petroleum is typically moved through pipelines, tanker ships, trucks, and railcars. Pipelines are the most common method for long-distance transport, while tanker ships are used for overseas shipments. Trucks and railcars are used for shorter distances and to access areas not connected by pipelines.
