petroleumi
Petroleumi, also known as petroleum or crude oil, is a naturally occurring, yellowish-black liquid found in geological formations beneath the Earth's surface. It is a complex mixture of hydrocarbons, primarily alkanes, cycloalkanes, and aromatic hydrocarbons, along with smaller amounts of nitrogen, oxygen, and sulfur compounds. Petroleum is believed to have been formed from the remains of ancient organisms, such as zooplankton and algae, that were deposited in marine or lake beds millions of years ago. Over time, these organic materials were buried under layers of sediment and subjected to heat and pressure, transforming them into petroleum.
The extraction of petroleum, known as oil drilling, involves drilling wells into the Earth's crust to access
