Typical Applications

Application

Enhanced Oil Recovery (EOR) - Nitrogen Flooding

Nitrogen is compressed to high pressures (30-50MPa) for injection into low-permeability reservoirs, displacing residual crude oil and increasing recovery by 10-20%. This process improves oil displacement efficiency by making crude oil more fluid.

Gas Lift Production

High-pressure nitrogen is injected into the annular space between tubing and casing, reducing liquid density and creating a pressure difference for smooth crude oil flow to the surface. Precise control of nitrogen injection ensures stable production in complex multiphase flow systems.

Workover Operations - Nitrogen Well Killing

Nitrogen is pressurized to balance well pressure during workover, preventing blowouts and not contaminating the oil layer. The compressor allows for precise pressure control based on reservoir and wellbore pressures.

Workover Operations - Nitrogen Well Washing

Compressed nitrogen mixed with well-washing fluids enhances the fluid’s carrying capacity, removing impurities and blockages more effectively than conventional methods while safeguarding long-term production capacity.

Safety - Inerting Protection

Nitrogen is supplied at the right pressures to reduce oxygen concentration below 12%, preventing fire and explosion risks in areas with explosive gas mixtures.

Safety - Fire Extinguishing

In case of fire, nitrogen compressors supply nitrogen to dilute oxygen in the combustion area, extinguishing the fire quickly with minimal environmental impact and aiding in rapid production restoration.

Pressure Testing

Nitrogen is pressurized for testing pipelines, pressure vessels, and other infrastructure, detecting leaks or structural defects based on pressure drops due to nitrogen leakage.
