Oil and Gas

The oil and gas industry has two sectors: the upstream sector and the downstream sector. Workers in the upstream sector find and produce crude oil and gas. Workers in the downstream sector produce useful things from crude oil, like fuel for cars and planes.

The first step in finding oil and gas is exploration. Scientists study rocks and do scientific tests. They look for rocks that can hold hydrocarbons. Oil and gas are made of hydrogen (H) and carbon (C). So we call the hydrocarbons.

Scientists choose a good place for the next step: drilling. Drillers drill a well, and they sometimes find hydrocarbons. The production doesn’t start immediately after drilling. First the company does more tests and asks “How much oil is there?” and “Are there any problems?” If the results of the test are good, they go to the next step: development. Development means they prepare for production. For example, they build a pipeline to transport the oil. The development takes from a few weeks to many years. Then production starts. Crude oil and/or gas flow from the well and along the pipeline.

Petrochemical plants produce chemicals from hydrocarbons. This plant gets light hydrocarbons from a refinery and produces ethylene (C2H2) and other important chemicals. Many industries use ethylene: for example they use it to make plastics, detergents and car tyres. Petrochemical plants produce millions tonnes of chemicals per year.

Petrochemical plants produce millions tonnes of chemicals per year. The production is controlled by computers. But computers can’t do everything. They often need a technician to open and close the valve or check some data.

The top producers of petrochemicals are countries in North America and Europe. But this is changing. Now many countries in Asia and the Middle East are building new petrochemical plants, and petrochemical production is going up fast in these countries.

Saudi Arabia, for example, is hoping to be the number 3 producer of petrochemicals in the world in 2015.

This is good business because petrochemicals sell at higher prices than crude oil. It is good for employment too. Population in Asia and the Middle East are going up, so these countries need new jobs for their young people.

Oil and gas companies are planning to increase world gas production by 50% before 2030.

Big gas producers like Russia, Saudi Arabia, Qatar, Iran and the UAE are increasing their production fast. Gas production in Africa, Europe, Asia and the Americas is growing too.
