Submersible pumping plant

Journal of the Institution of Electrical Engineers, 1960
Submersible pumping units have been developed to a sufficiently high degree of reliability and efficiency to capture a large part of the field previously held by the conventional borehole pump with surface motor. The paper commences with a description of the submersible pump and the submersible motor as separate units, together with sectional drawings,

Life of Submersible-Pump Components

Russian Engineering Research, 2018
Calculations of the total life of submersible-pump components (the screw and cage) are analyzed. On the basis of Ivashkov’s recommendations, a calculation method is proposed for the screw, which is the weak link in the system.

Electrical Submersible Pump

2020
Electrical Submersible Pump (ESP) in oil and gas industry is a multistage centrifugal pump used to lift moderate or high volumes of fluids from wellbores. In other words, ESP is one of the artificial lift methods that uses a downhole pump to provide an additional energy or additional lift to fluids inside the wellbore and hence improve hydrocarbon ...

A Variable Speed Submersible Pumping System

SPE Annual Technical Conference and Exhibition, 1979
Abstract A major new artificial lift system has been developed which will enhance the economics of many waterflood projects in West Texas and other recovery operations around the world. The new lift system consists of a standard oil well submersible pump and motor, a downhole pressure and temperature monitor and a ...
