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...

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, ...

pressurized irrigation is a recent development that consumes more energy for the pressure produced. in thisstudy, energy consumption, waste and efficiency were investigated at a diesel and electrical sprinklerirrigation pumping plant in some fields in hamadan province during 2007-8. nebraska performance criteria(npc) were used to compare sprinkler irrigation pumping plant performance. the resul...

The purpose of this study was to describe the development a solar-powered submersible pump system without use batteries in agriculture. used solar drive run it. implementation uses combination trackers, water storage tanks, power converters, and stabilizers. results explained that trackers increased efficiency units track sun throughout day convert energy into DC electrical power.

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...

Abstract Artificial lift is a vital part of the life many oil wells worldwide. Using several artificial methods can prolong and increase recovery significantly. One most applied nowadays electrical submersible pump (ESP). This method has ability to handle large volumes hydrocarbons applicable under conditions in both offshore onshore reservoirs. Even though ESP been extensively for years, it st...
