Nitrogen probable use6 Mar 2020 14:15
Coil tubing:
Nitrogen generators, equipped with high-pressure booster compressors, are increasingly being used to deliver gaseous nitrogen in a growing number of coil tubing operations. Coiled tubing units have replaced conventional rotary units and readily perform well displacements, cleanouts, jetting operations, gas lift procedures, and numerous other workover techniques. Coil tubing also transports acids and reactive chemicals down the wellbore and tubing corrosion is a concern. Low density, high-pressure gaseous nitrogen is ideal for these applications.
Well completion/workovers: The low density, high pressure properties of nitrogen make it ideal for use in a variety of well completion applications such as cementing operations (including control of cement slurry weights), pressure-activated devices, well cleaning, and fluid displacements. High-pressure nitrogen can displace drilling fluids, reduce hydrostatic heads, and allow the well to resume production. The use of nitrogen in cleanout operations does little or no damage to the formation and may enhance well production and longevity.
