Hydrofracking or "fracking" is a stimulation technique that is used to increase the amount of natural gas that can be extracted from the shale. The technique is widely used for oil and gas in the U.S and has been used for several decades.

Good thing about hydrofracking

One of the first things I think of that is good about hydrofracking is that the method is very effective and useful. The method is cheap compared to what you get out of the method. So the raw materials to get out of it such as oil and gas. Out of the raw materials can make a variety of fuels. The method is very simple. The very resources needed for this efficient method is easy to obtain. Hydrofrackings principle consists in spraying a mixture of water (90%), sand (9.5%) and additives (0.5%) into the wellbore under high pressure.

It's also a great way to raise oil production and gas production, easily and quickly.

Hydrofracking can also be good for the Danish economy if it is going to go successful here in Denmark. If we mean to use this method in most places in Denmark will it lead that we get thousands of new jobs. It will be good for the state unemployment such surfaces. Something quite different is that if it gets really popular in Denmark, we get energy independence that is we can manage our own energy and fuel. So we are free from buying from abroad.
