Nitrogen is added to acid blends and fracturing fluids to provide additional energy to assist in well clean up or to enhance the well flow rate. nitrogen is also used for removing fluids from wellbores, purging vessels, and pressure testing operations. nitrogen services are used primarily in applications supporting Calfrac’s coiled tubing and fracturing services.

Nitrogen is often pumped into the wellbore to safely improve the recovery of introduced or produced fluids, while reducing the potential for damaging the formation. The newest application is the use of nitrogen pumped at high rates to stimulate methane production from dry coalbeds.
