Areas of effective application of submersible centrifugal pump installations with and without a gas separator

Operating modes study on the use of submersible centrifugal pumps, with and without gas separator, in wells has been performed. It showed that the use of a gas separator with a constant separation coefficient does not always lead to an increase in the well production. The study showed also that in the area of low gas content, the supply of the pump with a gas separator is slightly less than without it. While at high gas contents, the use of a gas separator leads to an increase in the well production - the greater well production, the higher the gas content at the pump inlet.
