Hydraulic fracturing

Fracking fluids are sent down a wellbore at high pressure in order to create fissures in the underground formation in order to release trapped oil or gas. Nitrogen or carbon dioxide are used in foam-based fracking fluids.

Nitrogen is used as a high-pressure purging gas or to move industrial pig through a pipeline to clean out the walls. Nitrogen can also be used to pressurize pipes for transfering products and used in conjuction with helium for leak detection.
