this paper presents the effect of high viscosity oil and two-phase foamy-oil flow on the performance of a single stage centrifugal pump. as a part of this, the applicability of a pipe viscometer to determine the foamy oil viscosity is investigated. unlike previous studies, a sealed fluid tank is used in a closed flow loop to allow conditioning the two-phase mixture to create foamy-oil. furtherm...

Case Services' software provides production optimization for a variety of different methods of artificial lift. This paper discusses the dominant factors in electrical centrifugal submersible pump design and monitoring. Emphasis is placed on three areas: • Well inflow performance behavior. • Fluid Pressure-Volume-Temperature and phase behavior. • Pump equipment performance specifications. An ex...

The electric submersible pump, also known as ESP, is a highly effective artificial lift method widely used in the oil industry due to its ability deliver higher production rates compared other methods. In principle, ESP multistage centrifugal pump that converts kinetic energy into dynamic hydraulic pressure necessary fluids at rate with lower bottomhole pressure, especially wells under certain ...

Background: Under severe operating conditions, such as lubricant contamination, elevated temperatures and high unit loads, the hydrodynamic (HD) lubrication condition in a HD bearing may degrade and be reduced to mixed and boundary lubrication conditions, which traditional pad bearing materials (Babbitt metal) are not able to sustain. For example, Electrical Submersible Pump (ESP) systems are r...

Abstract Electrical Submersible Pump (ESP) is one of the major Artificial Lift methods that reliable and effective for pumping high volume fluids from wellbores. However, ESP not recommended applications with gas liquid ratio. The presence free inside pump causes performance degradation which may lead to problems or even failure during operations. Thus, it important investigate effect on under ...
