Thread: What Is Petroleum

Petroleum in its thickest form is called bitumen. Bitumen is mainly used for paving roads. Bitumen is also popular in waterproofing roofs. It can be mixed with sand or clay and water to produce what is known as oil sands. Oil sands are similar to tar, but the materials are naturally occurring. Bitumen is a nearly solid form of oil and is very expensive to process into gasoline or other usable fuels.] Therefore, oil sands are being mined almost exclusively to extract the oil, convert it into synthetic oil, or it is being refined for other petroleum products, such as plastic.]

Crude oil is a form of petroleum that is in a more liquid state than bitumen. It is mostly black or brown, but can also be yellow or green depending on its components. Crude oil from Sudan is black and North Sea oil is dark brown.
