Delivering Nitrogen when and where it’s needed

At Canadian Nitrogen Services, we eliminate the challenges logistics associated with resupplying nitrogen. We utilize state-of-the-art stand-alone membrane nitrogen generators for onsite supply of N2. Without the need to haul liquid nitrogen, we are able to provide service to remote locations quickly and safely. While other nitrogen suppliers haul product to every site and convert liquid nitrogen to gas onsite, our system is already interconnected and calibrated ready to generate N2 as required.

Our mobile generation units are used for a variety of functions and applications in the construction of oil and gas wells. The applications range from UBD to the completion phase of new wells, to clean out and stimulation in work-over or intervention programs.

Nitrogen applications

An industry standard technique for the replacement of a hazardous or undesirable atmosphere with an inert dry atmosphere.

Using nitrogen offers a number of advantages for drying operations. Membrane nitrogen contains only trace quantities of moisture, making it very effective in drying operations (nitrogen gas dew point is between -80°F and -90°F [-62°C and -67°C]). 

Nitrogen provides an inert atmosphere for long-term preservation once the drying process is completed. This environment reduces oxidation and no purge is required after drying is complete. Nitrogen also provides time savings since it can be used to rapidly pressurize a system.

During refinery shutdown, it is desirable to reduce the temperature of process catalysts as quickly as possible. Large volumes of nitrogen can be pumped by CNS pumping equipment to assist in the cooling process and save valuable hours of shutdown time.

In some circumstances, when hydrostatic testing is not possible, components or systems may be tested with nitrogen. However, system design specifications must be reviewed and a detailed risk analysis completed before testing with a compressible medium.

Nitrogen is used in well applications to reduce the weight of fluid in the wellbore. Nitrogen is pumped through coiled tubing (or gas lift tubing) and discharged at the well perforations. As the nitrogen gas flows up the production casing, it expands and reduces the weight of fluid in the column, allowing the well to flow.
