Heightened the petroleum productivity of an eruptive well by an electric submersible pump with a free gas separator

Analyzing Efficiency of Joint Operation of Gas Separator and Screw Pump on High-viscosity Gas-liquid Mixture

“…They did not specify an important parameter for evaluating the efficiency of ESP application -viscosity of the gas-liquid mixture, and also did not specify the condition under which they conducted a comparative evaluation, for example, the influence of the operation of the preinjection module as part of the pumping unit. It is known that ESP and ESPP can provide the same technical and technological characteristics in relation to the conditions of operation of one well, but at the same time, for example, a gas separator will be installed as part of ESP, while in the ESP arrangement there is no gas separator (25). Therefore, to choose the method of operation for hydrocarbon fields with hard-to-recover reserves, it is recommended to take into account not only the influence of the gas factor and the depth of equipment descent, but also the viscosity parameter of the gas-liquid mixture, energy indicators of the deposit (gas saturation, saturation pressure, reservoir pressure, etc.…”
