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...

According to the problem of screw fracture of electric submersible pump unit in Shengtuo oilfield, the reasons for the screw fracture are analyzed from three aspects: material, strength and pretightening force. The preliminary result shows that the imbalanced pretightening force of screw is the main reason of screw fracture. By means of Ansys software, the static and modal analyses for the elec...

Quality function deployment (QFD) help to realize significant reduction in product design cost and development time. The QFD process includes ranking customer preferences, rating the competitors, and parts deployment for the new or existing product. This study is carried out to understand the QFD concepts and implement this concept into the redesign of Monoblock submersible pump according to th...

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...
