Hello steemians Friends

Oil and crude oil consist of a complex mixture of hydrocarbons and other chemical elements, and the components vary considerably in terms of where and how they are formed. Chemical analysis of components is used to determine the source of oil. Crude oil and petroleum are similar in characteristics and components as we will explain in the article.

Where oil is located

Oil and natural gas used to supply homes, transport, factories and others are powered by a few spaces called pores between layers of buried rocks deep into the earth. For example, offshore wells are drilled thousands of feet offshore, tens of thousands of feet under sediments at the bottom The oil is then transported to the refineries and pumped into fuel or basic chemical products. Oil is produced in more than 100 countries, most of which produce oil and natural gas together.
