Oil and Gas

Produce nitrogen when and where it's needed.

 


 

PCI is the leading manufacturer of integrated mobile and portable nitrogen generation equipment for the oil & gas industry. We offer both on-site gaseous and liquid nitrogen production solutions in diesel or electric drive options. Our innovative nitrogen systems are specifically designed with the operator and applications in mind - ease, efficiency, and reliability of operation.

 

Oil and Gas Nitrogen - Performance Range:

 

    DESCRIPTION FLOW (scfm) PRESSURE (psig) PURITY (% N2)
           
UNDER-BALANCED
DRILLING
(UBD)
  Drilling operation where the pressure in the wellbore and bottomhole is less than the formation, allowing for production during drilling as well as protection of the formation. Nitrogen is commonly used because of combustion issues, and to far lesser extent, corrosion issues. 1500-3000 1500-3000 95%+

UBD 
SURFACE EQUIPMENT INERTING
  During UBD operations, potentially explosive reservoir fluids are collected and processed in special four phase separator vessels and collections tanks on the surface. These tanks are inerted with N2 to prevent an explosive environment. 300 4000 95%+

COILED TUBING OPERATIONS   

Coiled tubing is a flexible coil of piping that is run down a well and used in workovers, drilling operations, and fracturing. Nitrogen is sent down the hole to stimulate production, clean out debris, etc. Can also be used for shallow drilling and UBD horizontal drilling.Â

350-3000 1000-10000 95%+

PIPELINE PURGING & DRYING   Dry nitrogen is used to displace hydrocarbons in a pipeline or push a "pig" down a pipeline during cleaning operations. N2 is also used to dry chemical pipelines to very low dew points, or for general inerting during plant turnarounds. 100-3000 300-3000 95%+

CEMENTING   Adding nitrogen to a cement slurry will reduce the cement hydrostatic pressure column but still maintain compressive strength. This is done when the formation pressure is too low to hold the hydrostatic pressure column of cement to cover and separate zones. 200-1500 1000-3000 95%+

WELL COMPLETIONS & WORKOVERS   Wells are sometimes capped off after drilling operations are concluded, and perforating the production string and displacement of the hydrostatic fluid head must be done to get the well to flow on primary pressure. Workovers are subsequent cleanouts performed on a regular basis to remove hydrostatic fluids 350-3000 1000-5000 95%+

GAS LIFT   Introducing N2 in the produced oil product lightens the fluid, and the gas helps carry the lighter fluid to the surface. This is a secondary or enhanced oil recovery technique 300-3000+ 1000-5000 95%+

NITROGEN FLOODING   Injection of nitrogen is used to push a miscible front through a reservoir which pushes banks of displaced oil to production wells. 1000-3000+ 1000-5000 95%+

RESERVOIR PRESSURE MAINTENANCE   When the primary pressure of the reservoir is gradually depleted over time, additional energy must be added to the reservoir to drive the reservoir products to the surface. N2 or natural gas is used to provide this additional pressure. 1000-3000+ 1000-5000 95%+

FRACTURING   Nitrogen is used as a carrier gas for a number of chemicals, including acids, and various proppants used to fracture a reservoir to increase the permeability and total oil recovery of the well. 1000-5000 2000-10000 95%+
