Well stimulation by nitrogen injection
Nitrogen injection is an effective method for well stimulation and production enhancement. By introducing gaseous nitrogen into the well, the hydrostatic pressure of the fluid column is reduced, facilitating the flow of hydrocarbons to the surface.
Why nitrogen?
- Inert and non-corrosive gas
- Non-flammable
- Easy to generate in situ using membrane or PSA systems
- Low cost and minimal logistical requirements
- Versatile for multiple applications
Applications in oil fields
- Well stimulation in low-permeability reservoirs
- Temporary gas lift
- Cleaning of wells with high fluid loads
- Inerting of lines and equipment
- Pressure control in hydraulic fracturing operations
