Air Products supplies high volumes of nitrogen for coiled tubing used in workovers, drilling operations, and fracking. A flexible coil of piping is run down a well and nitrogen is sent down the hole to stimulate production, clean out debris, and other applications. As of January 2011, the Intervention and Coiled Tubing Association reported 494 coiled tubing rigs in the U.S., which represented nearly double the amount of units in 2005. Various sources estimate that the U.S. consumed 50% of the world’s coiled tubing in the past year, leading to increased nitrogen demand for this application.
We can supply nitrogen in quantities as low as 20,000-50,000 scf/job to blow out the coil after downhole use or as high as 5-15 MM scf/job for well clean-out and stimulation.
Nitrogen flow may vary between 350-3,000 scf/min and pressure may range from 1,000-10,000 psig.
