Öljyntuotanto, or oil production, is the process of extracting petroleum from beneath the Earth's surface. This process involves drilling wells into underground reservoirs, where oil is trapped. The primary methods of oil production include primary, secondary, and tertiary recovery.

Primary recovery is the initial extraction of oil from a reservoir. This is typically done using natural pressure or by pumping water or gas into the reservoir to force the oil to the surface. Once the natural pressure declines, secondary recovery methods are employed. These methods involve injecting water or gas into the reservoir to maintain pressure and displace additional oil towards the well.

Tertiary recovery, also known as enhanced oil recovery, is used when primary and secondary methods are no longer effective. This can involve techniques such as injecting carbon dioxide, steam, or chemicals to further displace oil from the reservoir.

Oil production is a critical component of the global energy industry. It provides a significant portion of the world's energy needs and is used in various applications, including transportation, electricity generation, and industrial processes. However, oil production also has environmental impacts, including habitat destruction, water pollution, and greenhouse gas emissions.

The oil industry is regulated by various government agencies to ensure sustainable practices and minimize environmental harm. Technological advancements continue to improve the efficiency and environmental impact of oil production.
