Calfrac provides coiled tubing services by injecting coiled tubing into wells to perform various well servicing operations.  Coiled tubing units are often used together with the appropriate support equipment to pump nitrogen, acid or air into wells in order to remove unwanted corrosive acids, solids, gels and fluids from the wellbore and producing zone.  Coiled tubing units can also be used to set and remove tools, perform well abandonments and set siphon or velocity strings, which promote the production of natural gas without the accumulation of fluid in the wellbore. 

Since 1999, Calfrac has successfully developed innovative equipment and treating procedures required to effectively complete coiled tubing assignments, from relatively simple shallow natural gas operations to the high‑tech, deep natural gas projects.
