Calfrac makes wide use of nitrogen (N2) in its well fracturing and coiled tubing operations. We add it to acid blends and fracturing fluids to provide additional energy to assist in well clean-up. We also use it to remove fluids and solids from wellbores during clean-up operations, for purging vessels, and in our pipeline pressure-testing operations. Its inert nature makes nitrogen well-suited to purging applications.
Nitrogen’s uses are continually evolving. One of the newer applications is high-rate N2 fracturing of dry coalbeds to enhance methane production.
The inert and non-toxic nature of N2 – it forms approximately 78 percent of the Earth’s atmosphere – makes it safe to handle and use, a genuine green material.
