The statistics of using downhole electric submersible pump (ESP) units in the oil fields Eurasia show that hydroabrasive wear is a common cause ESP emergency failures. authors this study theoretically and experimentally investigated peculiarities water–abrasive components. research methodology construction laboratory bench are described, results experimental studies determination changes abrasi...

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...

In an Electric Submersible Pump (ESP) lifted oil field, the ESP of each oil well should be operated inside its operating window. The total power consumed by the ESPs in the oil field should be minimized. The speed of the ESPs and the production choke valve opening should be optimally chosen for maximizing the total oil produced from the oil field. At the same time, the capacity of the separator...

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...

Electric submersible pump (ESP) is the core artificial lift equipment to production oil from underground or deep sea surface. Its energy efficiency significantly affects global market and consumption. To explore effects of impeller meridian profile on hydraulic performance, a typical multi-stage ESP with medium specific speed was taken as research object. Based statically determinate control sh...

Deep geothermal energy systems employ electric submersible pumps (ESPs) in order to lift geothermal fluid from the production well to the surface. However, rough downhole conditions and high flow rates impose heavy strain on the components, leading to frequent failures of the pump system. As downhole sensor data is limited and often unrealible, a detailed and dynamical model system will serve a...

The performance of the electric submersible pump (ESP) significantly affected by Gas Void Fraction (GVF). Thus, using of a Rotary Gas Separator (RGS) is a suitable solution for this issue. The performance of the RGS is function of different parameters such as geometry of impeller, rotating speed, boundary conditions, media viscosity and GVF. In this study, the influences of GVF, viscosity, and ...

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 ...

The availability of various koi pond pump products is marketed with kinds, types, and advantages. This diversity makes it difficult for business owners to determine a product that suits their needs. consideration the in question form an electric submersible or ESP. One method can be used selection AHP (Analytical Hierarchy Process) method. study uses assisted by expert choice software. From res...

94 Production from heavy-oil fields in the UK continental shelf (UKCS) has become possible over the past 10 years. Despite substantial reserves in the UKCS of crudes with gravitiy of 20°API and lower, most of the activity has been exploration and appraisal drilling. The main reason for restricted activity has been high uncertainty of reservoir and fluid properties. A method was developed to fin...
