Oil and gas
Nitrogen application
Enhanced oil recovery
In some of EOR projects, nitrogen can be used to flood marginal fields.
Pigging and purging
Nitrogen can be used as the driver to push the pigs through the pipe. Nitrogen can also be used to purge the pipeline after pigging has been completed.
Well stimulation
Nitrogen lifting is used to initiate production on a well following workover or overbalanced completion. A coiled tubing string is used to apply the treatment, which involves running to depth while pumping high-pressure nitrogen gas.
