How Is Oil Extracted From The Ground

How Is Oil Extracted From The Ground?

Conventional oil is extracted from underground reservoirs using traditional drilling and pumping methods. Conventional oil is a liquid at atmospheric temperature and pressure so it can flow through a wellbore and a pipeline – unlike bitumen (oil sands oil) which is too thick to flow without being heated or diluted.

How deep do oil wells go?

Back when records began oil wells were an average of 3 635 feet deep. But that was 65 years ago – and since 1949 we have used up these ‘shallow’ reserves. Oil is a finite resource meaning we now have to dig deeper to find it – with the 2008 average depth coming in at an average of 5 964 feet.

Conclusion: how long will fossil fuels last? It is predicted that we will run out of fossil fuels in this century. Oil can last up to 50 years natural gas up to 53 years and coal up to 114 years. Yet renewable energy is not popular enough so emptying our reserves can speed up.
