What Does
Gas Injection Rate Mean?
An injection rate can be defined as the volume of fluid or gas injected into a well during pumping in which the fluid or gas is artificially lifted using a downhole pump. During gas lift operations, the oil production rate increases as gas injection rate increases. As the injection rate of gas increases, the producing oil well will experience a decrease in gravitational pressure drop while experiencing an increase in frictional pressure drop.
Trenchlesspedia Explains Gas Injection Rate
With increase in gas injection rate, the oil production rate increases till it reaches the peak and then begins to decline. During the lifespan of a well, the rate of oil production may be lesser than expected requiring the use of an artificial technique to lift it. Gaslift is a method that is reliable and simple and does not require the use of a downhole pump.
Compressed air is injected into the lower section of the tubing to enhance the productivity of the well by mixing with the liquid column and reducing the its density and viscosity, making it easier for the fluid to reach the surface.
