    What is Air and Nitrogen Injection?

    An Air or Nitrogen Injection application involves injecting air or nitrogen during the underbalanced drilling process.



    Air Nitrogen Injection 2

    Injection

    By using an air or nitrogen injection during underbalanced drilling; the reservoir pressure remains low, increasing production by allowing the oil and gas to flow while drilling. In addition, the drilling rate typically increases as an underbalanced condition is approached.



    Air Nitrogen Injection 3

    Drilling Fluid

    In conventional drilling, drilling fluid is pumped into the well shaft at high pressures to hold the oil in the reservoir while drilling.



    Air Nitrogen Injection 4

    Balance

    Excessive overbalance can slow the drilling process by strengthening the near-wellbore rock and limiting removal of drilled cuttings under the bit.




  • Recommendations for Air and Nitrogen Injection Applications

    Ariel offers application specific components, engineered to ensure the performance, safety, and reliability of your air and nitrogen injection applications.

    Drilling services require increasing injection pressures. Final injection pressures are often short term. As such, discharge temperatures are often allowed to increase to relatively high temperatures. Special piston ring and valve plate materials are applied for these services.
