Öljyraakaaineiden

Öljyraakaaineiden refers to crude oil in Finnish. Crude oil is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth's surface, which can be refined into various types of fuels, including gasoline, diesel fuel, and jet fuel. It also serves as a feedstock for many chemical products, such as plastics, synthetic fibers, and solvents.

The formation of crude oil is a complex geological process that occurs over millions of years. It begins with the decomposition of organic matter, primarily marine plankton and algae, that accumulates on the ocean floor. This organic material is then buried under layers of sediment, where it is subjected to high pressures and temperatures. Over time, these conditions transform the organic matter into kerogen, a waxy substance that can then be further converted into liquid petroleum.

Crude oil is extracted from underground reservoirs through drilling. Once extracted, it is transported to refineries, usually by pipelines, tankers, or rail. At the refinery, crude oil is separated into its various components through a process called fractional distillation. Different fractions have different boiling points, allowing them to be separated at specific temperatures. These fractions are then further processed to create usable products.

The global oil market is a significant factor in the world economy. Oil prices are influenced by a multitude of factors, including supply and demand, geopolitical events, and economic growth. The extraction, refining, and consumption of crude oil have substantial environmental impacts, including greenhouse gas emissions and the risk of oil spills.
