... to churn-bubbly regime. Introduction Gas-lifting is achieved by injection of gas to the bottom of the wells to decrease the density of the fluids in the well's column, and accordingly decrease the gravitational pressure gradient without increasing much of the frictional losses. The gas-lift efficiency...
